Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.

    How the perception of ET contact changes humans

    Thanks everyone for your well wishes. And thank you Darci for you know what. You shouldn’t have ! It is much appreciated !!!

    I am still crook today but have dragged myself into my study to write this. I’ve been naughty the last few days. I should have stayed away from all electronics but I haven’t. Some of that time I have been reading the Kindle re-release of John Mack’s “Passport to the Cosmos”. I first read some of John Mack’s books in the mid 90s’ and I have a feeling I read some of this book in a local library, but back then I was still coming to grips with my own experiences and some of the things that were explored in his books were outside of my conscious understanding. So now as I read this book, it’s all so easy to digest. I don’t agree with all of the insights of the so-called abductees but I can respect how they see things. I greatly admire the way that John Mack connected with their entire experience and nurtured many of them to a point of acceptance.  I think it is the best book ever written about the ET contact experience. My only wish is that John was able to connect the contact experiences and their subsequent spiritual transformations to the work of Carl Jung and the Transpersonal psychologists and anthropologists.

    So every night when I go to bed for the last 3 nights, I’ve been thinking about the contact experience and what it means to me. As a result of this I’ve had some new insights, that I’ll try share over the next few months.

    For now I’d like to say something about how the perception of ET contact changes humans.

    I’ve talked before about the contact phenomenon following a DEVELOPMENTAL CONTINUUM, where a person grows through the experience and subsequently shifts in their perception of the experience. What I haven’t said before is that everybody is different. Every body changes in their experience of ET contact but not everybody experiences a change in their perceptions of contact. Some people seem to stay fixed in their perceptions of what has been happening to them. And that to me, seems a real shame for the folks who see only bad aliens.

    What seems to happen to me, is that the experience itself changes across the life span, depending on how old we are and where we’re at psychologically and spiritually. Initially, it seems like we have no control and we experience an inability to remain conscious. We may discover that strange medical procedures were carried out on our body and strange interactions done with our mind. Gradually we become aware of our experiences and may even be conscious through part of an experience or an entire experience. During this phase we may be shown things or taught things about all manner of subjects. John Mack’s abductees all seemed to be taught about the preciousness of life on this planet and the need for us to change our ways to save Earth from mass extinctions. Later we may be taught about the true nature of reality and who the ETs are and where they come from. During either of these phases we may be given tours around the craft. Later when we have lost all fear, we are given full opportunity to interact with the sentience of craft – through enjoying a room of our own, learning from the craft, enjoying food from the craft, toileting, bathing or showering and piloting the craft. From this point onwards, contact seems evolve into a combination of opportunities and activities – which include visiting other worlds and meeting many different races (although you may meet other races at any stage). Through out all phases, you will receive regular monitoring and assessments of your physical and emotional health.

    But not everyone seems to seems to have these opportunities and if they do, they don’t perceive them as opportunities. The diagram below is a rough effort on my part to show the movement or lack of movement in perception and growth that takes place in people who have contact with beings from other worlds. I’ve attached the name of some people who you may know from this field and I’ve also attached the names of some researchers.

    DC4

    To make this diagram, I’ve had to make certain judgements and I could be wrong about my perceptions of these individuals. So what this diagram shows is my perception of the general changes in certain individuals. So take Credo Mutwa, who is well known to David Icke followers. Credo sees the ETs as parasitic aliens, who are using humans for their own benefit. He has continued to perceive contact as traumatic and painful. But while angry with the aliens who control Earth, he perceives that he has gained benefit from the knowledge they have given him. Whitley Strieber seems to be somewhere in the middle. And although he was aware of his contacts before many other people and has explored them in great depth, he still seems to see them with a degree of ambiguity, uncertainty and concern. Mike Clelland of Hidden Experience blog  http://mikeclelland.com/ / http://hiddenexperience.blogspot.com.au/, has been grappling with contact in a public way, for quite a while now and my sense is that Mike is still very suspicious of those orchestrating his contacts. Mike is open but equally uncertain. Rachel Bree, my ex -wife is at the other end of the continuum. She met Dude when she was 4 years old and has always known what the ETs are really like. Despite some discomfort with unexpected events, she has always trusted and looked up to the ETs and knows they love and care for her. (She doesn’t feel that way about humanity though !). When I spoke to my son Toa, he put himself now about 3/4 of teh way along teh continuum – suggesting he’s still a bit frightened of letting go. I place my self  now at the far end but initially when I started having conscious encounters, although I was always excited, I was admittedly a little scared. In the same group I also place Bernado Peixoto and Sequoyah Trueblood – (abductees who feature prominently in Passport to the Cosmos). And while Passport to the Cosmos contains a number of so called abductees who I would think of as embodying a very strong New Age Mythos, many of them could also be placed in the same group.

    You”ll notice that I have also added some researchers. David Jacobs, seems to have maintained the same view of contact – that humanity is dealing with an alien threat, that seeks to use and abuse us. Bud Hopkins, despite a great deal of pioneering work remains an alarmist of sorts who sees aliens as intruders who are doing terrible things to humans. John Mack, came from a place of great uncertainty and in his time, I think came to recognize the ET contact experience in the same way that many contactees do – as a form of encounter with teh divine. It seems to me, that not only do those who have contact experiences pass through some sort of Developmental Continuum (whether their is a radical shift in their perceptions or not) but those who research the subject also pass through a Developmental Continuum – which seems to reflect the same sort of inner features. This in turn seems to be reflected in the populous. And hence now, we can see a multitude of divisions that fit somewhere along the same kind of continuum.

    In a lot of the community work I did I noticed that the “squeaky wheel”, the one that most the made noise, got the most attention and sadly, I think the same is true in this field. Those who have the loudest voices are the ones declaring how insidious and bad the aliens are. If only we had another John Mack !

    What do these difference in initial and changing perceptions reflect ? I’m not sure. But I think it may reflect several things. First how willing we are to accept challenges to our world view and accept the need for change in our world view. Second, different temperaments, seem to be predisposed to being Victims and others to being Empowered by experience. Third, I suspect that Victim type personalities have a long and probably unknown/suppressed history of trauma and that Empowered type personalities have come in contact with their traumas and integrated them into who they consciously are. Fourth – the innate ability to trust, seems to be lacking in Victims. Fifth – everybody is a product of their conditioning via family systems, education, work, society, religion, ethnicity, nationality, interests etc. Those with rigid conditioning that has entrapped them in certain ways of thinking, may end up developing Victim type personalities who see ET contact as a hostile alien abduction, driven by ulterior motives. Those who can see the impact of their conditioning on their thought processes, may end up developing Empowered personalities who see ET contact as connection with the divine. Sixth – those that perceive the universe to be determined by an internal locus of control are OK with whatever happens, while those who perceive the universe to be determined by an external locus of control

    There seems to be to me a kind of feedback loop going on in the psyche of all who have encountered ET contact. If you start off as a Victim type personality, you seem to internalize the idea that you are controlled and life isn’t fair. And unless you get past that idea, you will never get to to become the Empowered type personality that seems to internalize the idea that you control how you react to everything and that life is fair. If you latch on too tightly to those dark ideas of absolutely having to have control over this body, you are going to suffer immensely. And the same is true whether you’re sick with disease and need to trust others to help heal you or care for you or whether you need to trust in what the ETs are doing. There is so much attachment to the body and those that are heavily attached, can talk all they want about spirit but unless they let go of that attachment to controlling the body, they will never understand spirit and the boundlessness of spirit. If a human abducted me and did things to me, despite my knowledge of spirit, I wouldn’t like that because I know what cruelty humans are capable of. Still I would try to relinquish the need for absolute control. But an ET can take me anytime because I trust in their intentions and can move past the challenges which come to the body.

    I think perhaps the most important thing about the contact phenomenon, is that it cracks open our perception of reality and in the aftermath of dealing with that, we have a choice about how we integrate what has happened to us and our new perceptions of reality. Do we choose to look favorably on what we have learned or do we recoil in horror ? If we look favorably we begin to see all of life as an opportunity for growth and development and feel deep connection to ALL things. If we look unfavorably we begin to see threats everywhere and life as an exhausting process of frustration and self defense. Ultimately it’s all about whether we embrace separateness or wholeness. If we embrace wholeness, we accept that separateness is am aspect of the whole. If we embrace separateness, we never accept or embrace the whole.

    So these are all generalizations. I am not saying they’re strictly true for everyone but I think there are strong correlations between those who see themselves as victims (and if they don’t they act as victims) and those that feel empowered.

    In the past and future history of this subject there will always be people like Credo Mutwa and people like me – people who see both ends of the spectrum and who avidly support what they believe to be true. You must decide for yourself what is true for you !

    I can’t tell you how you should feel about the experience of contact. All I can do is tell you what I have learned about myself, the ETs and the experience of contact. And if you go out and try to have contact and you’re successful, you may learn for yourself that the ETs mean us no harm and are here to nurture us.

    John Mack confirmed this when he in Passport to the Cosmos he said :

    “…relate their abduction experiences to a kind of cosmic game in which a lonely Creator learns Itself through a splitting of consciousness – “an explosion into the multiplicity of Self,”…Out of the primordial potential, God spawns beings who separate from Him and then choose to reconnect. But in the case of humankind, the experiment went awry, as many of us have lost connection with the creative principal altogether. The alien beings seem to play a part in reconnecting the experiencers to the Creator or Source.”

    In an interview on NBC

    (http://www.bibliotecapleyades.net/vida_alien/alien_abductionabductees25.htm) John Mack suggested :

    The purpose of doing this work,” Dr. Mack replied, “is to open us to the idea that the universe may be vastly more interesting, containing entities, energies, beings that we did not know existed. When we open that consciousness, we open to a larger reality. We’re not simply Earth-bound in our consciousness as if we were the top intelligence in the cosmos. We come more modestly to realize we are in connection with energies, beings, whatever it may be that is beyond ourselves. And that would be a very healthy development for this species, it seems to me.”

    And that to me is what the ET contact experience is about in a nutshell. Whether we see the ETs as manifestations of the Divine/Source/God is irrelevant. We’re in contact with a larger reality, that is within us and within which we co-exist. When we open up to that, we have no choice but to grow and transform our limited perceptions about reality and the nature of Self.

    How Often Do Ice Ages Happen?

    How Often Do Ice Ages Happen?
    About 700 million years ago, during the Cryogenian glaciation, runaway glaciers made Earth look like a snowball.
    Credit: NASA

    The last ice age led to the rise of the woolly mammoth and the vast expansion of glaciers. But it's just one of many that has chilled Earth throughout the planet's 4.5-billion-year history.

    So, how often do ice ages happen, and when is the next freeze expected to begin?

    The answer to the first question depends on whether you're talking about big ice ages or the little ice ages that happen within those larger periods. Earth has undergone five big ice ages, some of which lasted for hundreds of millions of years. In fact, Earth is in a big ice age now, which explains why the planet has polar ice caps. [Photo Gallery: Antarctica's Pine Island Glacier Cracks]

    Big ice ages account for about 25 percent of Earth's past billion years, said Michael Sandstrom, a doctoral student in paleoclimate at Columbia University in New York City.

    The five major ice ages in the paleo record include the Huronian glaciation (2.4 billion to 2.1 billion years ago), the Cryogenian glaciation (720 million to 635 million years ago), the Andean-Saharan glaciation (450 million to 420 million years ago), the Late Paleozoic ice age (335 million to 260 million years ago) and the Quaternary glaciation (2.7 million years ago to present).

    These large ice ages can have smaller ice ages (called glacials) and warmer periods (called interglacials) within them. During the beginning of the Quaternary glaciation, from about 2.7 million to 1 million years ago, these cold glacial periods occurred every 41,000 years. However, during the last 800,000 years, huge glacial sheets have appeared less frequently — about every 100,000 years, Sandstrom said.

    This is how the 100,000-year cycle works: Ice sheets grow for about 90,000 years and then take about 10,000 years to collapse during warmer periods. Then, the process repeats itself.

    Given that the last ice age ended about 11,700 years ago, isn't it time for Earth to get icy again?

    "We should be heading into another ice age right now," Sandstrom told Live Science. But two factors related to Earth's orbit that influence the formation of glacials and interglacials are off. "That, coupled with the fact that we pump so much carbon dioxide into the atmosphere [means] we're probably not going to enter a glacial for at least 100,000 years," he said.

    A hypothesis put forth by the Serbian astronomer Milutin Milankovitch (also spelled Milanković) explains why Earth cycles in and out of glacials and interglacials.

    As the planet circles the sun, three factors affect how much sunlight it gets: its tilt (which ranges from 24.5 degrees to 22.1 degrees on a 41,000-year cycle); its eccentricity (the changing shape of its orbit around the sun, which ranges from a near-circle to an oval-like shape); and its wobble (one full wobble, which looks like a slowly spinning top, happens every 19,000 to 23,000 years), according to Milankovitch.

    In 1976, a landmark paper in the journal Science provided evidence that these three orbital parameters explained the planet's glacial cycles, Sandstrom said.

    "Milankovitch's theory is that the orbital cycles have been predictable and very consistent throughout time," Sandstrom said. "If you are in an ice age, then you'll have more or less ice depending on these orbital cycles. But if the Earth is too warm, they basically won't do anything, at least in terms of growing ice." [Doomsday: 9 Real Ways Earth Could End]

    One thing that can warm Earth is a gas such as carbon dioxide. Over the past 800,000 years, carbon dioxide levels have fluctuated between about 170 parts per million and 280 ppm (meaning that out of 1 million air molecules, 280 of them are carbon dioxide molecules). That's a difference of only about 100 ppm between glacials and interglacials, Sandstrom said.

    But carbon dioxide levels are much higher today when compared with these past fluctuations. In May 2016, Antarctica carbon dioxide levels hit the high level of 400 ppm, according to Climate Central.

    Earth has been warm before. For instance, it was much warmer during the dinosaur age. "[But] the scary thing is how much carbon dioxide we've put in [the atmosphere] in such a short period of time," Sandstrom said.

    The warming effects of that carbon dioxide will have big consequences, he said, because even a small increase in Earth's average temperature can lead to drastic changes, he said. For instance, Earth was only about 9 degrees Fahrenheit (5 degrees Celsius) colder, on average, during the last ice age than it is today, Sandstrom said.

    If global warming causes both Greenland's and Antarctica's ice sheets to melt, the oceans will rise about 196 feet (60 meters) higher than they are now, Sandstrom said.

    The factors that caused the long ice ages, such as the Quaternary glaciation, are less well-understood than those that led to glacials, Sandstrom noted. But one idea is that a massive drop in carbon dioxide levels can lead to lower temperatures, he said.

    For instance, according to the uplift-weathering hypothesis, as plate tectonics pushed up mountain ranges, new rock became exposed. This unprotected rock was easily weathered and broken apart, and would fall into the oceans, taking carbon dioxide with it.

    These rocks provided critical components that marine organisms used to build their calcium-carbonate shells. Over time, both the rocks and the shells took carbon dioxide out of the atmosphere, which, along with other forces, helped lower carbon dioxide levels in the atmosphere, Sandstrom said.

    A shrine built over a cave that is revered as the tomb of Jesus is in danger of "catastrophic" collapse, according to a report by National Geographic.

    Repair and restoration work at the Edicule has been going on for the past year, during which the limestone bed that Jesus' body was supposedly buried on was revealed. Today (March 22), National Geographic reported that the Edicule is in danger of "catastrophic" collapse if further repairs are not undertaken soon. [Read more about the dangers at the shrine.]

    Female cockroaches don't need a mate to lay eggs, but they do like company. New research finds that virgin female cockroaches housed together are quicker to produce offspring than virgin females living alone.

    To test the effect of social milieu, the researchers put female cockroaches in different situations. In the control group, a male and a female were housed together and were allowed to mate. In other cases, females were kept with one, two, three or four other females. Other female roaches were kept with castrated males. The researchers also tested the effects of adding pheromones, chemicals that insects use for communication, to all-female cockroach groups. [Read more about the strange habit.]

    Hundreds of World War I-era liquor bottles have been uncovered at a buried British barracks in Israel.

    The excavators unearthed the foundations of an agricultural building from the Ottoman Empire — which ruled Israel from 1517 until the end of World War I — that had apparently been repurposed as housing for British soldiers during the war. [Read more about the British bottles.]

    Cancer is caused by mistakes in DNA, and a new study finds that in most cancer cases, these mistakes are completely random; they're not due to heredity or environmental factors, but rather the result of random errors.

    Scientists had thought these mutations resulted mainly from two things: Either the mutation was inherited, or it was caused by outside factors that can damage DNA, such as cigarette smoke or ultraviolet radiation, the researchers wrote. But a third cause — random mistakes — actually accounts for two-thirds of these mutations, said the new study, published today (March 23) in the journal Science.

    Stephen Hawking does not feel welcome in Donald Trump's America. The renowned physicist made this unhappy claim in a recent interview, and he expressed particular concern about how the Trump administration is treating the issue of climate change.

    Hawking, who once called Trump a "demagogue," said the new U.S. president was elected by "people who felt disenfranchised by the governing elite in a revolt against globalization." [Read more about the his fears.]

    Greek archaeologists have found the ancient military harbor of the island of Salamis — the very physical space from which the largest and most decisive naval battle ever fought in antiquity was launched.

    The survey identified remains of port structures, fortifications and other buildings dating from the Classical period (from the fifth to fourth centuries B.C.) and Hellenistic period, on all three sides — north, west and south — of the bay. (The beginning of the Hel lenistic period is usually marked by the death of Alexander the Great in 323 B.C.) [Read more about the ancient base.]

    UFO Repairmen From The Stars? No!

    Last year I wrote an article here at Mysterious Universe titled “UFOs: Extraterrestrial? Probably Not.” One of the reasons I gave for suggesting that the UFO phenomenon is far stranger than anything of an E.T. nature, is the fact that many UFO incidents seem to be staged for the benefit of the witness. As if “they” are trying to convince us they are extraterrestrials. But, they are trying way too hard. I made mention of one particular angle of the UFO phenomenon that, in my opinion, is a perfect example.

    I wrote:

    QUOTE: “There’s the nature of the entities themselves: they practically overemphasize who, or what, they claim to be. Take, for example, all those ‘soil-sampling’ aliens of the 1950s and 1960s. You know the ones: someone is working in their field, or driving down a stretch of road, when they encounter a couple of diminutive aliens collecting specimens of local plants, flowers, and vegetables. E.T. on a scientific mission, right? No, not in my view.

    “We only have to take a careful look at such cases (and there are more than a few on record – here’s a link to a number of classic cases) to see that these ‘incidents’ are clearly stage-managed. It’s a game, a scenario that has nothing to do with real soil-sampling, but everything to do with trying to emphasize the ET meme. Are we to believe that, time and time again, aliens are so stupid that they can’t collect a few of those aforementioned samples without having their cover blown? Of course, they could easily avoid us! But, here’s the deal: they want to be seen. It’s not an accident. It’s carefully planned. And it’s designed to plant an image of ‘E.T. scientists’ in the mind(s) of the witness(es).” END OF QUOTE.

    Today, I’m going to highlight another – equally absurd – aspect of Ufology. I’m talking about the many reports of people stumbling on aliens “repairing” their craft. Like the supposed extraterrestrials who endlessly take soil samples, “the repairers from beyond” are also spectacularly useless when it comes to the issue of avoiding being seen. Of course, the truth is (as per my words above) that they want to be seen. Yet again, to add weight to the E.T. meme. Let’s take a look at a few incidents.


    Richard Hall

    The late UFO researcher Richard Hall recorded a couple of such cases: “November 25, 1964 New Berlin, NY: Twelve humanoids observed at distance after two discs landed on hill; appeared to be engaged in repair operation for hours. September 18, 1978 G. Filiputti, Melaria, Porto Nogaro, Italy 3:30 P.M.: One 1-meter-tall humanoid, silver tight-fitting coveralls, almond eyes, emerged from disc with dome, appeared to be making repairs on rim.”

    Then, there is this at UFO Evidence, from March 30, 1995: “When a local farmer from Groot Marico in the western Transvaal plains region first observed the saucer-shaped object on Thursday morning, he noticed that it had a distinctly visible hole in its hull. The farmer, Mr. Jan Pienaar (45), is of the opinion that this ‘vehicle’ landed on a remote country road between Coligny and Brakspruit to have its damaged hull repaired. However, his arrival probably prompted the ‘vehicle’s’ hasty retreat and rapid ascent into the sky.”

    In 1976, John Brent Musgrave wrote an article for Flying Saucer Review magazine titled “Saskatchewan, 1933: UFO Stops For Repairs.” Musgrave said in his article: “During the summer of 1933 stories drifted into Nipawin [Canada] that some homesteaders, as well as a forest tower ranger, had been observing strange lights in the sky and near the ground. Whatever it was, they had been seeing it for the better part of a week.” Musgrave added that according to three witnesses to a landed UFO in Nipawin: “The Occupants appeared to be slightly shorter than the average man, and were all dressed in what appeared to be silver colored suits or uniforms. All appeared to be wearing helmets or ski caps, and all were busy running around ‘repairing’ the craft.”

    I could go on and on. But, you get the picture. Aliens are so advanced that they can travel the Universe, but when they come here, to Earth, they are endlessly plagued by problems of the “mechanical” kind. And when and where there just happens to be someone around to see them replacing the equivalent of a spark-plug or changing a tire. Nope. Something else is afoot. I don’t know why the UFO phenomenon plays such bizarre mind-games with us. But, it does. If we can figure out why, we may be halfway towards figuring out the real nature of the UFO phenomenon.

    'Life' is an alien horror movie that riffs on some eerily plausible science

    Warning: Some spoilers for "Life" are ahead if you haven't seen the movie.

    • "Life" is a space horror movie starring Jake Gyllenhaal, Ryan Reynolds, Rebecca Ferguson, and more.
    • The plot is about a Mars sample return mission gone terribly wrong.
    • The film's creators worked with real scientists to make it more believable.
    • NASA is actually working on getting a Mars sample to Earth and is worried about contaminating the planet.

    Big-budget science-fiction movies aren't supposed to be documentaries.

    They are, however, supposed to take us on journeys to far-flung places, immerse us in vivid alternate realities, and make us wonder "what if?"

    But reality itself is a powerful filmmaking spice that, justly applied, helps suspend our disbelief — and sometimes scream our guts out.

    Such is the case with the new movie "Life", whose makers consulted a NASA-trained medical doctor, a Mars spacecraft engineer, and a geneticist to help produce their horrifying spectacle.

    While the film, directed by Daniel Espinosa, whiffs on quite a lot of science, it does go far enough to be wildly entertaining. In fact, Business Insider's Jason Guerrasio even argues it may be a cult classic in the making.

    We join the story just as a Mars sample return spacecraft is being caught by a small crew aboard the International Space Station (ISS). With red dirt in hand, NASA astronauts go about analyzing the grit behind several "firewalls" of protection.

    After an extraterrestrial microbe is discovered in the soil, it's revived in a soup of water and nutrients. Then, to the astonishment of the crew, it springs to life. "Calvin," as the life form is soon called, quickly divides and grows into a starfish-size creature with incredible strength and intelligence.

    What could possibly go wrong?

    To understand what doses of reality went into the movie, we called up Dr. Kevin Fong ― a medical doctor, space medicine expert who's trained with NASA and ESA for about a decade, and a paid science consultant for the new Sony Pictures film.

    And to answer some of those "what if?" questions on aliens, we spoke to Catharine A. Conley, a planetary protection officer for NASA who gets paid to help humankind avert extraterrestrial disasters in the real world.

    "Life" features not one but two characters who are doctors, so filmmakers brought Fong on board to answer their pressing questions.

    A lot of the early work happened by email, he says, but soon enough Fong was invited to join the set: an elaborate and modular reconstruction of the space station inside a giant green-screen studio.

    "They paid more attention to detail than I'd seen in the space agencies," Fong told Business Insider. "Although the modules are different than what they actually are on the space station, it was very close."

    The producers occasionally asked Fong to lend his expertise in physiology and emergency care to actor Jake Gyllenhaal (who plays long-duration astronaut David Jordan), actress Rebecca Ferguson (who plays Center for Disease specialist Miranda North), and others in various scenes.

    "There are a couple of quite dense medical scenes, where I'd say, 'I'd hold this tool like that,' or 'I wouldn't hold that in the way you are,' and 'here's some terminology I'd use in this situation.' On the set, it came across as a very believable," Fong says.

    He was especially impressed with a cardiac arrest scene, saying it was "about as faithful as one could be" in a movie.

    While he hadn't seen the movie, at least at the time Business Insider interviewed him, Fong didn't walk away thinking it'd be a documentary.

    "I think it pays dividends to any movie producer to go as far as you can in suspending disbelief," he says. "But I'm not expecting 'Apollo 13.' You have to make the drama more realistic without getting in the way of the story."

    Fong also said that while there are definitely parallels to the "Alien" space horror movie franchise, "Life" is imminently more believable.

    "Around the time 'Alien' was made, you needed to imagine some far-flung place," he says. But with the ISS floating just 250 miles above Earth, he added, "this is happening right on your back door."

    Fortunately for us, NASA has put decades of thought into protecting planet Earth.

    Defending the planet from real-life Martians

    At first blush, the idea of a Mars sample return mission might seem far-fetched. But NASA researchers hope to do just that in the future.

    In fact, both Congress and President Trump essentially codified that mission for the space agency by passing the NASA Transition Authorization Act of 2017 into law in March.

    The first line of defense for a Mars sample is Catharine Conley, who is NASA's sole planetary protection officer. She has worked in that role since 2006, and helps ensure Earth's microbes don't reach other worlds — and other worlds' microbes don't reach Earth, at least in an uncontained way. (And that includes keeping dead bodies off of other worlds.)

    "The phrase that we use is, 'break the chain of contact with Mars,'" Conley told Business Insider.

    Conley also hadn't seen the movie, but said if a Mars sample was flying toward Earth, it would be aimed slightly off-course from the planet. That way if something goes wrong, the capsule full of red dirt (and maybe a harmful microbe) wouldn't enter our atmosphere in an uncontrolled way, break open, and induce panic.

    Yet before such a capsule would ever leave Mars, she says,international guidelines require that an multi-governmental, multi-space agency committee convene to review the mission and make a recommendation on what to do.

    "You'd want the international community to weigh in because it's a of a high-enough concern," she said. "There's a lot of checks and balances."

    A Mars sample return mission — ostensibly to seek fossilized signs of ancient life, not actual microbes — wouldn't be the first to test the mettle of protections for Earth: Apollo 11 astronauts had to stay quarantined for three whole weeks in a trailer before emerging.

    In fact, she says, planning for a Mars sample return mission started with the nuclear-powered Viking landers of the 1970s and has been going ever since.

    Plans "got the most carefully laid out" in the early 2000s, she said, but by then, bringing a sample to the space station had long been ruled out.

    Thereason? It seemed far too expensive to ship equipment and experts into space, where they'd be ask to excel in a free-floating (and very foreign) environment). Also, containing a disastrous microbe inside the ISS seemed like a pointless step.

    "The space station is going to fall down at some point," she said.

    Instead, Conley says scientists would make sure an extra-robust capsule carefully reenters Earth's atmosphere, is quickly retrieved, and hurried away to a Biosafety Level 4 laboratory — the most high-security grade of research facility on the planet. There, scientists could meticulously analyze their invaluable prize to no end.

    "I would love to find life elsewhere," Conley said — if for no other reason than to compare it to life here on Earth, where the only organisms we know of exist. "If Earth and Mars life are related, that makes things a lot more complicated."

    Bemanning platformbevoorradingsschip ziet enorme UFO opstijgen uit Golf van Mexico

    Bemanningsleden van een platformbevoorradingsschip hebben in de Golf van Mexico een UFO gezien die ‘vijf keer’ zo groot was als hun schip.

    Men is nu op zoek naar andere getuigen die mogelijk meer informatie hebben over de waarneming.

    De UFO is dinsdagavond gezien op een kleine 130 kilometer van New Orleans, schrijft nieuwssite gCaptain.

    Vijf keer zo groot

    Een bemanningslid, de hoofdingenieur van het schip, meldde zich bij het National UFO Reporting Center (NUFORC), dat gegevens over UFO-waarnemingen bijhoudt.

    “Op 21 maart zag ik rond 19.00 uur samen met vier andere bemanningsleden een vaartuig dat vijf keer zo groot was als ons 73 meter lange schip,” liet de getuige weten.

    “Op ongeveer 800 meter achter ons bevond zich een olieplatform,” zei hij. “Dat gebruikte ik om de omvang van het vaartuig te schatten.”

    Oogwenk

    “Het tafereel duurde ongeveer 40 seconden,” vervolgde hij. “Het schip steeg op uit het water (Golf van Mexico). Er droop geen water vanaf.”

    “In een oogwenk schoot het vaartuig weg,” klonk het. “In luttele seconden was het volledig uit het zicht verdwenen.”

    De hoofdingenieur zei verder dat het schip een donkere kleur had, ovaalvormig was en geen enkel geluid maakte.

    Zeer betrouwbare getuige

    Aangezien er twee booreilanden in de buurt waren, moeten er volgens de man meer getuigen zijn geweest.

    Hij schat dat aan boord van andere bevoorradingsschepen in de buurt zo’n 50 mensen waren.

    NUFORC besloot contact op te nemen met de man en liet weten dat het hier gaat om een nuchtere, zeer betrouwbare getuige.

    Astronaut who walked on the moon makes INCREDIBLE alien revelation

    THE FOURTH man to set foot on the moon has opened up about aliens – and what he saw.

    By Rachel O'Donoghue 

    ALIEN APPEARING CLEARLY ON OLD NASA APOLLO 11 PHOTO

    Alan Bean, 85, was the lunar module pilot on Apollo 12 in November 1969 – just months after Neil Armstrong and Buzz Aldrin.

    And the time he spent up in space has led him to a fascinating theory about alien life.

    Mr Bean said he is utterly convinced that aliens are out there – despite scientists finding no real evidence of their existence.

    There must be statistically many planets around many stars that have formed life

    Alan Bean

    He told news.com.au: “There're so many billions of stars and these stars have planets around them so there must be statistically many planets around many stars that have formed life,” he said.

    “Maybe some of them are like our life was 100,000 years ago, and some of them are like we are now, and there are probably some out there that are 10,000 years in the future from where we are now.”

    However, he does not believe extraterrestrials have touched ground – just yet.

    REVEALED: Astronaut Alan Bean revealed his theory about aliens

    He said: “I do not believe that anyone from outer space has ever visited the Earth.

    “One of reasons I don’t believe they have been here is that civilisations that are more advanced are more altruistic and friendly – like Earth, which is better than it used to be – so they would have landed and said ‘we come in peace and we know from our studies you have cancer that kills people, we solved that problem 50 years ago, here’s the gadget we put on a person’s chest that will cure it, we will show you how to make it’.

    “Just like some day, say 1000 years from now, when we can go to another star and see a planet, that’s what we would do because we will know how to cure cancer, cure birth defects, so we would teach them.”

    VIDEO Gisteren is de eerste commerciële vlucht naar het zuiderlicht geland in Nieuw-Zeeland. De 134 passagiers waren op zijn zachtst uitgedrukt onder de indruk van het groene licht, vergelijkbaar met het noorderlicht, en deelden hun prachtige ervaring op sociale media.

    Ever wondered what an aurora australis looks like from 60 South from a Boeing 767? Wonder no more… 

    Het acht uur durende avontuur begon donderdagavond op het Zuidereiland, een van de twee grote eilanden waaruit Nieuw-Zeeland bestaat. De Boeing 767 vloog zuidwaarts, waar de passagiers volgens expeditieleider Ian Griffin, directeur van het Otago Museum, "een spectaculaire vertoning" kregen.

    "Niemand heeft dit ooit eerder gedaan", zegt hij aan de BBC. "Dit was een wereldprimeur in het zuidelijke halfrond." Griffin benadrukt dat de expeditie niet zo eenvoudig te organiseren valt als een normale vlucht. "Het zuiderlicht verschijnt niet zomaar op een specifieke locatie. Het beweegt in het rond, en we probeerden het achterna te jagen boven de Zuidelijke Oceaan."

    Het chartervliegtuig ging meerdere keren door het zuiderlichtgebied en vloog tot 66 graden zuiderbreedte.

    Glorious view from , Antarctic circle, Orion Nebula, beams - just has everything!

    Woah! Nice trip through the southern auroral zone tonight on  Naked eye auroras were spectacular photographically!

    Huge congrats to @iangriffin & crew for making  a reality. @FlyAirNZ is this the most impressive wing shot ever? 

    Voor de passagiers was het tripje zeer gedenkwaardig. "Onze levens zijn voor altijd veranderd door deze ongelooflijke ervaring. We zijn eeuwig dankbaar dat we deel konden uitmaken van dit opmerkelijke gebeuren", wordt Roz Charlton geciteerd door The Guardian.

    Daar moesten de deelnemers uiteraard iets voor over hebben. Een ticket voor de speciale vlucht kostte 4.000 Nieuw-Zeelandse dollar (2.600 euro) in economy en 8.000 dollar (5.200 euro) in business class. 

    Geïnteresseerden kunnen alvast beginnen sparen, want gezien het succes plannen de organisatoren volgend jaar een nieuwe expeditie.

    Dirk Frimout vertrok 25 jaar geleden als eerste Belg naar de ruimte - HLN.be

     Bron: Belga

    VIDEO Op 24 maart 1992, vandaag/vrijdag precies 25 jaar geleden, werd Dirk Frimout aan boord van het Amerikaanse ruimteveer Atlantis de eerste Belg in de ruimte. Hij wentelde 143 keer rond onze planeet, goed voor een missie van 8 dagen 22 uur 9 minuten 28 seconden. Waarnemers hadden het over een "Amerikaans-Belgische vlucht", want nagenoeg de helft van het wetenschappelijk lab Atlas-1 in de vrachtruimte van de shuttle was (co-)Belgisch. Onder de instrumenten was er onder meer een rasterspectrometer die Frimout als wetenschapper van het Belgisch Instituut voor Ruimte-Aëronomie mee had ontwikkeld. Overigens kreeg de West-Vlaamse burggraaf het instrument na een panne tijdens de missie weer aan de praat.

    Frimout, geboren te Poperinge op 21 maart 1941, maakte geen deel uit van het astronautenkorps van het Europese Ruimtevaartbureau ESA. Precies door zijn wetenschappelijke bagage bovenop een reeks toevalligheden kon Frimout zijn droom waarmaken. Dat hij alsnog als wetenschappelijk astronaut kon vliegen, was naar zijn zeggen "niet het winnen van een lot in de tombola, maar het resultaat van 25 jaar voorbereiding en hard werken", plus blijven volhouden. 

    Tot nu toe is geen enkele Belg via de geijkte procedure in de ruimte geraakt. Zo werd bijvoorbeeld Frank De Winne later "heropgevist" nadat hij niet voor de tweede "astronautenklas" van ESA was geselecteerd. Frimout schrijft deze gang van zaken toe aan het feit dat de selectiecriteria voor astronauten bijzonder streng zijn terwijl er zeer veel - valabele - kandidaten zijn. "Het zijn de besten" die uiteindelijk effectief de aarde van bovenaf gaan bekijken, beklemtoont hij. Tegelijk stipt de astronaut aan dat er wel degelijk "subjectieve" elementen (voor een selectie) kunnen meespelen, zoals "ondersteuning door een land". 

    Dat een geselecteerde astronaut soms lang moet wachten op een vlucht, is dan ook weer geen zeldzaamheid, leerde Frimout uit gesprekken met astronauten. "Je moet volhouden, zelfs bezeten zijn".

    Zelfmoord

    Wat Frimout het meest is bijgebleven van zijn historische missie, is het moment dat de hoofdmotoren van de shuttle uitfloepten, het moment dat hij voelde net in de ruimte te zijn aangekomen en dus de gewichtloosheid te voelen. "Dat is uniek", zegt hij. "Het is de droom die je had en hij begint dan nog maar", aldus Frimout, die aangeeft dat de in 1986 ontplofte shuttle Challenger op dat moment ook wel in zijn hoofd zat. 

    Zijn zes collega's heeft hij - ondanks de "speciale band" die zij met elkaar hadden - voor het eerst weer samen ontmoet bij het vieren van de twintigste verjaardag van hun missie. Onder hen zijn gezagvoerder Charles Bolden, die later en tot voor kort hoofd van het Amerikaanse ruimtevaartbureau NASA was. Onder Bolden maakte de NASA een grote transformatie door, door de privésector uitdrukkelijker bij de ruimtevaart te betrekken. 

    Frimout zegt dat deze transformatie "zeer positief" is uitgedraaid. De inbreng van bedrijven als SpaceX was een "boost" voor de ruimtevaart. 

    Gevraagd of een privé-initiatief als Mars One, waarbij gegadigden een enkele reis naar de Rode Planeet zouden kunnen maken, geldklopperij is, beaamt hij. "Dit is niet ernstig, er zit niets achter, ze hebben zelfs nog geen raket", aldus Frimout die de "zelfmoord" van de kandidaten ook "ethisch niet verantwoord" vindt. "Dit geeft een verkeerd beeld".

    Budget

    Hij juicht toe dat er wel ernstige programma's zijn om naar analogie van het Apollo-Maanproject een mens veilig naar Mars te brengen en te laten terugkeren. Frimout verwelkomt in dit verband ook de inbreng van de privé-sector, want bijvoorbeeld de NASA "kan dit niet alleen". Dat er in 2040 voor het eerst een mens voet op Mars kan zetten, acht hij haalbaar. Maar daarvoor "zijn er nog de nodige inspanningen vereist".

    ESA schrapte in 1992 de plannen voor zijn eigen ruimteveer Hermes waarmee Europa de facto geen autonome bemande toegang tot de ruimte kreeg. Frimout wijst de mening af dat dit een onjuiste beslissing was. Hij wijst erop dat het Europese ruimtevaartbudget bijvoorbeeld maar een zevende van het Amerikaanse bedraagt en dat Europa wellicht niet te middelen heeft voor autonome bemande ruimtevaart. Toch heeft ESA wat bemande ruimtevaart betreft volgens de Belg "zeer goed werk" gedaan, bijvoorbeeld via de onbemande Europese cargo's voor het Internationaal Ruimtestation ISS en de servicemodule die het heeft ontwikkeld voor de toekomstige bemande capsule Orion.

    Weinig aandacht

    Frimout betreurt dat er in de media weinig of geen aandacht voor wetenschappen en ruimtevaart is. "De mensen hebben de indruk dat er niets meer gebeurt, maar dat is niet zo", beklemtoont hij. 

    De eerste Belg in de ruimte hekelt dat er in het middelbaar onderwijs bij wijze van spreken "geen woord valt" over ruimtevaart en dat die geen deel uitmaakt van de eindtermen voor het secundair onderwijs in Vlaanderen. Hoewel er initiatieven zijn van bijvoorbeeld ESA om ruimtevaart tot in de scholen te brengen, is Vlaanderen "een van de enige" onder de lidstaten die daaraan niet meedoen. Wel zijn er veel leraars die enthousiast zijn om initiatieven te (willen) nemen, en merkt Frimout zelf bij bezoek aan scholen hoe leerlingen geboeid zijn. Maar een omkadering is er niet.

    De pogingen van zijn eigen Euro Space Society om heuse "space teachers" in de Vlaamse scholen te lanceren, botsen ook op een institutioneel obstakel en een "gebrek aan openheid van geest": ruimtevaart is federaal, onderwijs is een bevoegdheid van de gemeenschappen.

    Vierde man ooit die op de maan wandelde: "Zo weet ik dat aliens nog nooit naar de aarde kwamen" -HLN.be

    Bron: news.com.au

    Alan Bean maakte deel uit van het tweede team astronauten dat naar de maan gestuurd werd. Hij hoort ook bij het selecte clubje van amper twaalf leden die ooit voet hebben gezet op de maan. De nu 85-jarige Bean zegt in een interview met news.com.au dat aliens nog nooit onze planeet aandeden. En waarom hij dat denkt.

    De Apollo 12 had maar drie crewleden aan boord toen het ruimtetuig op 14 november 1969 aan zijn missie begon. Tien dagen later landde de toen 37-jarige piloot van de maanlander, Alan Bean, terug op aarde en had hij als vierde man ooit op de maan gewandeld. De twee maanwandelingen die hij samen met zijn collega Charles 'Pete' Conrad had volbracht, duurden in totaal 7 uur 45 minuten 18 seconden.

    Vanuit zijn ervaring heeft Alan Bean zo zijn eigen theorieën als het over buitenaards leven gaat. "Ik denk niet dat er ooit iemand vanuit de ruimte de aarde heeft bezocht", zegt hij aan news.com.au. "Een van de redenen waarom ik dat denk, is dat beschavingen die meer geavanceerd zijn ook altruïstischer en vriendelijker zijn - zoals de aarde zelf vandaag beter is dan ze ooit was. Als ze dus hier zouden landen, dan zouden ze zeggen: 'Wij komen in vrede en we weten dat jullie moeten afrekenen met de ziekte kanker die mensen doodt. Wij hebben dat probleem 50 jaar geleden opgelost. Dit is het apparaatje dat wij op iemands borst plakken en dat kanker geneest. We zullen jullie leren hoe je het moet maken'."

    Kanker genezen
    Bean gaat verder: "Net zoals wij zouden doen als we pakweg over 1.000 jaar naar een andere ster kunnen reizen en een planeet zien, omdat wij zelf dan weten hoe we kanker en aangeboren afwijkingen moeten genezen en we het hen willen aanleren."
    Lees hieronder waarom hij zeker is dat aliens bestaan

    De voormalige astronaut - sinds 1981 overigens voltijds kunstenaar met de maan als thema - twijfelt er wel geen seconde aan dat aliens bestaan. "Er zijn miljarden sterren met allemaal planeten errond, dus statistisch gezien moeten er vele planeten zijn rond heel wat sterren waar er leven is", meent Bean. "Sommige zitten misschien in het stadium waar wij 100.000 jaar geleden zaten, andere staan dan weer waar wij nu staan en waarschijnlijk bevinden nog andere zich 10.000 jaar verder in de toekomst ten opzichte van ons." 

    Schilder
    Alan Bean, net 85 geworden, schildert vandaag nog altijd dagelijks. Hij werkt met maangereedschap en gebruikt onder meer "stukjes van Apollo-ruimtetuigen en een snuifje maanstof" voor zijn kunstwerken. Die gaan van de hand voor tienduizenden - soms zelfs honderdduizenden - dollars. "Ik ben dan ook de enige op aarde die dit soort schilderijen met levensechte ervaring kan maken", zegt hij.

    UFO Reported in Gulf of Mexico: OSV Engineer Says He Saw Large Craft Hovering Near Rig

    shutterstock_61875832-1
    Dramatization

    A crew member of an offshore supply vessel in the Gulf of Mexico claims he saw a UFO ‘fives times’ the size of his vessel and UFO trackers are now looking for more witnesses to come forward with any information possibly related to the sighting.  

    The UFO sighting reportedly occurred on Tuesday in the Gulf of Mexico approximately 80 miles southeast of New Orleans.

    The sighting was submitted to the National UFO Reporting Center, which apparently tracks UFO sightings and data, by the chief engineer of an OSV working the Gulf of Mexico on Thursday afternoon. According to the eyewitness report:

    “Close to 7:00 pm on March 21st, just before dusk, myself and 4 of the crew members aboard our vessel saw a craft that appeared to be five times our 240 ft vessel in length. My line of sight was about 1/4 mile from our vessel. There was a rig behind the craft about a 1/2 mile. i used this to help gauge size of craft. Sighting was approximately 80 miles SE of New Orleans, Louisiana.

    The scene lasted about 40 seconds. The craft rose up out of the water (Gulf of Mexico) about 40 feet, no water was dripping from the craft. Within a split second the craft disappeared at a 30 degree angle into the sky. Speed appeared to faster than speed of a light turning on in a room. Within seconds it had disappeared completely.

    I can say for sure that the craft was dark colored, oval in shape and made no sound whatsoever.

    With as many rigs (2), there has to be more witnesses than just the four on our vessel.

    The NUFORC has even highlighted the sighting as being of particular interest among the 246 reports of UFOs received in March alone. And after speaking with the witness by phone, the NUFORC said the report seems legit and has urged more witnesses to come forward. 

    “We spoke via telephone with this witness, and he seemed to us to be unusually sober-minded,” NUFORC wrote in a note added to the original report. “We suspect that he is a very capable, and very reliable, witness. He estimates that upwards of perhaps 50 people, who were aboard nearby vessels, may have witnessed the event, as well. We would urge those other witnesses to submit reports of what they had witnessed.”

    So, did you see a UFO in the Gulf of Mexico earlier this week?

    West Country Experiences Sudden Increase In UFO Sightings

    UK-UFO

    It appears that aliens have taken a renewed attention in the paranormal hotspot of the West Country. The increases in sightings and strange events in the part of the country have also gotten the interest of regional media as they reported the latest development in mysterious happenings, crop circles, and legends. Crop circles, in particular, are allegedly created or caused by alien visitors.

    Regional media recorded two UFO sightings in just weeks after the news of an alien being spotted in country town Yeovil in Somerset broke off.

    In December, there were reports of an alien being observed wearing a Stetson Hat close to Yeovil College vicinity.

    Just recently, two more unexplained sightings have been reported over the internet.

    A witness said to have seen a UFO in the sky above Lysander Road and the A3088 on March 4 in Yeovil.

    The witness, who chose not to be named, said he did not notice anything at the time when he took a photo of the scenery around Lysander Road. He described the environment as so bright that he could not see anything.

    He just noticed something strange in the photo when he got home. He saw an object that he thought was flying towards west.

    Another witness reported his sighting on February 21 at around 6:30 in the morning over Yeovil. The person managed to get a video recording using a static camera in his garden.  He stated in his report that he caught eight strange lights flying in an east to southeasterly direction.

    People in Gloucestershire also reported bizarre incidents.

    A video shows a mysterious light reportedly filmed above Gloucester at around 5 am on March 13. It is the second one showing unusual lights in the sky over the city.

    A day earlier, a video by Rob Wheatman shows an unknown light above Elmbridge. The witness said that it was sparkling like a star from the garden in Elmbridge.

    He also saw an orange light from it and flew at speed. He used his video camera with 40x zoom to get images of the light.

    Disc UFO over New Jersey was ‘football field’ size, claims witness

    A New Jersey witness at Lakehurst reported a 2014 incident where a disc-shaped object the size of a “football field” moved overhead and then quickly moved away, according to testimony in Case 82734 from the Mutual UFO Network (MUFON) witness reporting database.

    The object was seen hovering over Joint Base McGuire–Dix–Lakehurst. (Credit: Wikimedia Commons)

    The witness was driving home from work on December 10, 2014, when the incident began.

    “At the end of this one long, hilly road, you come to a four way stop,” the witness stated.“Diagonally, there is a large, empty field. And beyond that is the base. Once I got to the stop sign there was another car in front of me and we simultaneously saw something in the sky and hit the brakes immediately in the middle of the road.”

    The object was as large as a football field. (Credit: Google)

    The witness described the object.

    “There were 12 or more lights lined up in an oval shape larger than a football field. It could have been much bigger if it was further way. Similar to the Phoenix Lights. I just found that real quick as an example. But the oval shape was more pronounced. The ring or halo of lights were almost tilted on an angle. The lights lit up in a row. The oval sped up quicker and quicker until it vanished completely without a trace. The reason why I decided to write about this now is because I was driving past that field the other day and realized you can see stars everywhere in the sky, except for where those lights were above the base.”

    The object moved away very quickly. Pictured: Lakehurst, NJ. (Credit: Google)

    Lakehurst is a borough in Ocean County, New Jersey, population 2,654. Lakehurst Maxfield Field, sitting just north of the city, is the naval component of Joint Base McGuire-Dix-Lakehurst, a United States Air Force-managed joint base headquartered approximately 25 miles (40 km) east-southeast of Trenton in Manchester Township in Ocean County, New Jersey, United States. It is primarily the home to Naval Air Warfare Center Aircraft Division Lakerhurst, although the airfield supports several other flying and non-flying units as well.

    New Jersey MUFON Chief Investigator Ken Pfeifer is investigating. Please remember that most UFO sightings can be explained as something natural or man-made. The above quotes were edited for clarity. Please report UFO activity to MUFON.com.

    Euclid: ESA's Search for Dark Matter & Dark Energy

    Euclid is a mission planned by the European Space Agency (ESA) that aims to learn more about the parts of the universe we can't see — specifically, dark energy and dark matter. These form most of the universe and are thought to be responsible for phenomena such as the acceleration of the universe's expansion.

    Euclid is expected to launch in 2020 from French Guiana aboard a Soyuz rocket. It will take roughly 30 days for Euclid to make its way to its planned location in space, which is a gravitationally stable area known as a Lagrange point. Euclid will be at L2, which lies about a million miles from Earth but in the opposite direction of the sun. At this point, with the Earth, moon and sun behind it, a spacecraft can get a clear view of deep space.

    As a survey mission, Euclid will last at least six years and cover 15,000 square degrees of sky. Its survey will be performed as a "step and stare," meaning that the telescope will do measurements on about 0.5 square degrees of the sky at a time.

    The ESA's current guideline for science missions is called Cosmic Vision 2015-2025. In 2007, a proposal process for Cosmic Vision resulted in two missions that were intended to measure the geometry of the universe: DUNE (Dark Universe Explorer) and SPACE (Spectroscopic All Sky Cosmic Explorer.) 

    DUNE was supposed to image the sky across a wide field to study dark energy and dark matter. Its primary measurement method was weak gravitational lensing. SPACE was supposed to create a 3-D evolutionary map of the universe across 10 billion years, by measuring galaxy redshifts and spectra. However, after an assessment study those two missions were combined into one: Euclid. (Euclid is named after an Ancient Greek mathematician who is sometimes called the "father of geometry.")

    In 2011, ESA selected Solar Orbiter and Euclid as the first two of its medium-class or M-class missions, among several proposals. Solar Orbiter is expected to launch in 2018, and Euclid in 2019.

    In 2013, NASA signed a memorandum of understanding with ESA to provide 20 detectors for Euclid's near-infrared instrument. NASA also nominated 40 U.S. scientists to join the Euclid consortium, which builds the instruments and will later parse the mission's science data. Later that year, Italy's Thales Alenia Space was selected as prime contractor for the mission. Euclid passed its preliminary design review in 2015, and the first parts of the flight hardware — four detectors for the visible imager – were delivered to ESA in early 2017.

    We can only see a fraction of the known universe. Ordinary matter makes up about 4 percent, while dark matter makes up 20 percent and dark energy makes up 76 percent. Understanding more about dark matter and dark energy could help scientists, for example, learn why the universe is accelerating in its expansion. There is not enough "ordinary" matter to account for the acceleration.

    Euclid will show scientists more about the dark universe. One of its main goals is to accurately map galaxy redshift, which occurs when an object moves away from us. The light shifts to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter. The mission will look back to galaxies that formed as early as 10 billion years ago, or more than double the solar system's age. In its prime mission, Euclid will map about half of the sky.

    Specifically, Euclid's detectors are supposed to conduct two cosmological probes. One will study weak gravitational lensing, which happens when a concentration of matter bends light as light travels toward the observer. This is useful for mapping dark matter and for inferring dark energy by measuring how much galaxy images are distorted by the lensing.

    The other probe will study baryonic acoustic oscillations (BAO), which measures the spatial distribution of galaxies. Across very large scales, galaxies tend to cluster in pairs separated by a standard distance. This standard distance is linked to sound waves in plasma (supercharged gas) from the early universe; the sound waves propagated from dark matter halos, or concentrations of dark matter associated with galaxies. BAOs are therefore a standard ruler to measure the universe's expansion, and dark energy as well.

    Euclid's science will be performed by two instruments, and the spacecraft's 1.2-meter mirror will split light between them for analysis:

    • A visible imager (VIS), which will include dozens of charge-coupled devices specially formulated for the mission. ESA said the devices will include high efficiency, low noise and good radiation tolerance. The field of view of VIS is a little larger than the area covered by two full moons.
    • The Near-Infrared Spectrometer and Photometer (NISP), which will provide near-infrared photometry of galaxies. The aim is to combine NISP's and VIS's observations to show the galaxy redshift observed by Euclid.

    The overall goals of Euclid (in ESA's words) are:

    • Investigate the properties of the dark energy by accurately measuring both the acceleration as well as the variation of the acceleration at different ages of the universe;
    • Test the validity of general relativity on cosmic scales;
    • Investigate the nature and properties of dark matter by mapping the 3-dimensional dark matter distribution in the universe;
    • Refine the initial conditions at the beginning of our universe, which seed the formation of the cosmic structures we see today.

    Dark matter is still a relatively young science, but there have been some observations by other space missions to assist with Euclid's work.

    The Fermi Gamma-ray Space Telescope launched in 2008. One of its science goals is to look at dark matter, specifically by probing phenomena such as excess gamma-rays from the Milky Way's center. In 2014, NASA announced that the excess emission seen in that area "is consistent with some forms of dark matter." In 2017, observations of the nearby Andromeda Galaxy revealed the same phenomena.

    Other space missions have glimpsed dark matter, even though it wasn't in their primary missions. One example is a 2015 study of 72 galaxy cluster collisions that used data from both the Hubble Space Telescope and the Chandra X-Ray Observatory. At the time, scientists said the study helped set limits on the nature of dark matter. "Astronomers can map the distribution of dark matter by analyzing how the light from distant sources beyond the cluster is magnified and distorted by gravitational effects," the Harvard University Chandra X-Ray Observatory page said in a press release.

    Hubble also performed a survey that helped map out the distribution of dark matter in the universe, NASA said in a 2007 press release.

    ESA's Gaia mission launched in 2013 to create the most accurate map of star locations in the sky. It is thought that charting their movements will reveal more information about the nature of dark matter, and how it influenced the universe's history.

    Gliese 581c: Super-Earth Exoplanet

    Gliese 581c is a super-Earth planet that was discovered in 2007. It resides in the Gliese 581 system, which at 20 light-years from Earth is relatively close to our planet (in celestial terms). While early research suggested that Gliese 581c may have liquid water on its surface because it resides in its star's "habitable zone," more recent research suggests it may have a Venus-like environment.

    The existence of Gliese 581c was announced in 2007 in the journal Astronomy and Astrophysics. The paper was led by Stephane Udry, an astronomer at Geneva Observatory. Gliese 581c was one of two super-Earth planets his team found, both at the edge of the star's habitable zone. 

    Gliese 581c was found using the radial-velocity method, meaning that it was detected through tugs on its parent star. The instrument that made the discovery was the HARPS spectrograph on a 3.6-meter telescope managed by the European Southern Observatory in Chile. (HARPS is one of the more prolific planet-hunting instruments available to astronomers today.)

    At the time, the researchers said Gliese 581c is "the known exoplanet which most resembles our own Earth" because it was only five times the mass of our planet. (Subsequent searches have found many planets much closer to our Earth's mass.)

    While Gliese 581c was classified as Earth-like, the researchers cautioned that actual conditions on the planet may be very different than our own. The surface temperature, for example, would depend on the composition and thickness of the atmosphere. The atmosphere also determines how much light is reflected off the planet, and the magnitude of the greenhouse effect.

    The parent star of Gliese 581c, called Gliese 581, is an M-class dwarf star. It's cooler than the sun, which means its habitable zone would be closer in than our own solar system. M dwarfs are favored for planetary searches because they are dimmer, meaning that planets passing across the star would be easier to see. There also is a smaller relative size between the planet and the star, making their gravitational effects more obvious.

    Researchers examining Gliese 581 have had different opinions over the years about how many planets were there; one example was the discovery of Gliese 581g in 2010. Signatures of the planet did not show up in independent searches, and today most astronomers in that field consider that the planet does not exist. 

    Not knowing the number of planets exactly makes it difficult to determine the radius of Gliese 581c. The planet has not been seen directly passing across the face of its star, so astronomers can only learn about its characteristics from Gliese 581c's influence on other planets and the star. The radius would in turn determine such matters as whether the planet is closer to an Earth-like planet (with a smaller atmosphere) or closer to a Neptune-like planet (with a much thicker atmosphere). 

    Gliese 581c takes about 13 days to orbit its parent star. (By contrast, Mercury's orbit around our much larger sun takes about 88 days.) Because Gliese 581c is so close to its star, a common belief is that the planet is tidally locked. This means that as it orbits, the planet always keeps the same side toward the sun. This phenomenon is common among moons of Jupiter and Saturn in our own solar system. Earth's moon is also tidally locked to our own planet.

    If a planet is tidally locked, this means that one side (the star-facing side) is always warmer than the other side (which always faces away from the star.) Any considerations of habitability would have to take this into account. The only firm example of a habitable planet that we know of – our own Earth – has a regular day-night cycle in most areas of the planet, except the poles. Over billions of years, lifeforms have adapted to this cycle. It's unclear how life would survive in an area of perpetual day or perpetual night, but studies are ongoing.

    A 2007 follow-up paper in Astronomy and Astrophysics, led by Werner von Bloh at the Potsdam Institute for Climate Impact Research, suggested that Gliese 581c is too hot to support life because it is so close to its parent star. This means that the planet may have more of a Venus-like environment, with an extremely hot surface and a runaway greenhouse effect under a thick atmosphere. This was confirmed in a 2011 study in Astronomy and Astrophysics led by Y. Hu, who is with Peking University's laboratory for climate and ocean-atmosphere studies.

    While Gliese 581c has not been discussed much in scientific literature in recent years, astronomers are working more generally to improve their models of planets that are close in to their parent stars. An example is a 2013 article published in the journal Nature, in which a team led by Jeremy Leconte examines the conditions under which runaway greenhouse effects happen on Earth-like planets. This line of research is receiving increased attention again after the discovery of Proxima Centuari b, a potentially habitable planet just four light-years from Earth, in 2016.

    Dwarf Planet Ceres' Water-Ice Deposits Tied to Its Changing Tilt

    The location of newfound water-ice deposits on Ceres is linked to wild swings in the dwarf planet's tilt over the eons, a new study suggests.

    Ice on Ceres — the largest body in the main asteroid belt between Mars and Jupiter — survives in permanently shadowed regions that don't receive sunlight. But these regions change drastically over a period of just 24,500 years, researchers determined. 

    Ceres' tilt relative to the plane of its path around the sun changes tenfold, from 2 degrees to about 20 degrees, in that time. The dwarf planet's current tilt, also known as obliquity, is 4 degrees; by contrast, Earth's tilt (which is responsible for the seasons) is 23.5 degrees. [Amazing Photos of Dwarf Planet Ceres]

    "We found a correlation between craters that stay in shadow at maximum obliquity, and bright deposits that are likely water ice," study lead author Anton Ermakov, a postdoctoral researcher at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a NASA statement. "Regions that never see sunlight over millions of years are more likely to have these deposits."

    The last time Ceres reached its maximum tilt was 14,000 years ago. When the tilt of Ceres is at a minimum, which is close to the conditions happening right now, there are large portions of the dwarf planet — roughly 800 square miles (2,000 square kilometers) — that don't receive direct sunlight, most of which are near the poles, study team members said.

    This animation shows how the illumination of Ceres' northern hemisphere varies with the dwarf planet's axial tilt. Shadowed regions are highlighted for tilts of 2 degrees, 12 degrees and 20 degrees.

    But when Ceres' tilt gets closer to 20 degrees, the regions protected from sunlight diminish to just 0.4 to 4 square miles (1 to 10 square km). Those regions that remain in shadow even during maximum obliquity could be the same areas that maintain surface ice, the researchers said.

    The new study used data from NASA's Dawn spacecraft, which has been orbiting the 590-mile-wide (950 km) Ceres since March 2015, to take measurements of the dwarf planet's shape and gravity, and to try to reconstruct its history. It focused on polar craters and looked at how the shadowing shifts in these regions as Ceres' axial tilt changes.

    The researchers found that, in the northern hemisphere, only two of the persistently shadowed regions that exist today will still be dark when Ceres reaches a 20-degree tilt. Both regions have bright deposits today, which could indicate water ice. Two persistently shadowed regions are also present in the southern hemisphere, and one of those regions has a bright area, the researchers said.

    In 2016, a study that analyzed Dawn data indicated that there is bright material in 10 craters on Ceres. Dawn's Visible and Infrared Mapping Spectrometer determined that one of these regions contains water ice.

    Ceres isn't the only spot in the solar system known to have permanently shadowed regions on its surface; Mercury and Earth's moon also have these zones. However, Ceres has much more variability in its tilt because it is not stabilized by the sun (as Mercury is) or a planet (as Earth's moon is), the researchers said.

    While scientists believe that Mercury and Earth's moon both received most of their surface water from small, impacting asteroids and comets, there is more debate regarding Ceres. The European Space Agency's Herschel Space Observatory detected a tenuous water atmosphere around the dwarf planet in 2012 to 2013. This means that the ice could come from water falling back from Ceres' atmosphere, scientists have said, though the stuff could also come from small impactors.

    "The idea that ice could survive on Ceres for long periods of time is important as we continue to reconstruct the dwarf planet's geological history, including whether it has been giving off water vapor," study co-author and Dawn deputy principal investigator Carol Raymond, also of JPL, said in the same statement.

    The new study was published in the journal Geophysical Research Letters.

    'Life' Brings Alien Terror to the International Space Station

    No science-fiction movie that takes place at the International Space Station has been quite as terrifying as "Life," a new space thriller that comes out in theaters today (March 24).

    In the film, a Mars sample-return mission delivers the first proof of alien life to a group of astronauts at the International Space Station (ISS). What is at first a harmless, single-celled organism sealed inside a box in the lab grows bigger, stronger, smarter and bloodthirsty. When it breaks out of its container and comes after the astronauts, all hell breaks loose. ['Life' Movie Brings Terrifying Space Thrills (Photo Gallery)]

    The all-star cast who play the astronauts in "Life" do not disappoint. Jake Gyllenhaal stars as a doctor who has spent more than 473 days aboard the ISS. Rebecca Ferguson plays a microbiologist whose job it is to protect everyone at the station and on Earth from possible contamination by the alien. Ryan Reynolds plays the role of a spacewalk specialist and provides some necessary comedic relief to this gruesome story.

    The plot of "Life" is a bit of a mashup between the movies "Gravity" and "Alien." Just like in the "Alien" saga, the extraterrestrial in "Life" (which is nicknamed Calvin after school children on Earth won a naming contest) is out to kill every living thing aboard the spacecraft — in this case, the ISS. As the astronauts fight for their lives, they demolish the ISS. Though Calvin is the reason for their panic, the astronauts create more problems trying to kill it. 

    At times, the astronauts do things that would be considered foolish in real life, such as using fire to try to kill Calvin. (Starting fires is strictly forbidden at the ISS.) However, watching Ryan Reynolds blast flames at an octopus-like monster while chasing it around the ISS was worth the slight technical inaccuracy.

    Astronauts find the first proof of life on Mars in a sample brought to the space station. The creature, which they named Calvin, seems harmless at first before growing into a bloodthirsty monster.

    While the film is more of a horror flick than a science-driven narrative about extraterrestrial life and the International Space Station, there's plenty of real space science throughout the story to keep even hard-core space geeks entertained. The ISS is accurately and brilliantly rendered, and space-savvy viewers may recognize some of its features, such as the Canadarm robotic arm, the Cupola window and the docked Soyuz crew capsules.

    Despite the superb acting and production that went into the making of this film, the story left me feeling a bit unsettled and unsatisfied near the end. For a group of highly intelligent astronauts at the space station, the astronauts made a lot of bad decisions that only make matters worse. I would have expected better from a group of trained professionals with "the right stuff." Then again, it's hard to guess how astronauts in the real world would deal with a situation as crazy as this. After all, they are still humans.

    Overall, the film is worth a watch for anyone who's into space, horror, or both. But if you're expecting a heroic story of six brave astronauts who save the day, you might be disappointed with the ending.

    "Life" is rated R (for violence, gore, terror and profanity) and opens in theaters nationwide today (March 24).

    Breaking the 'Speed Limit': Simulation Shows Monster Black Holes' Rapid Growth

    They grow up so fast: A new simulation shows how supermassive black holes could have gotten so large, so quickly in the early universe — by taking a shortcut via a star.

    Supermassive black holes form the cores of many galaxies, including the Milky Way, and researchers have found evidence of them dating to very early in the universe's history. In fact, seemingly too early — supermassive black holes take a long time to form, and researchers have been searching for explanations of how they were able to grow so massive (several billion times the sun's mass) within the first billion years after the Big Bang, surpassing their apparent "speed limit" on growth.

    According to a new simulation, black holes can only grow so fast, but stars can expand to incredible size even faster in certain conditions before collapsing down into a black hole. That way, the energetic galactic centers can form earlier than expected. The researchers also explained their simulation in a new video.

    "It turns out that while supermassive black holes have a growth speed limit, certain types of massive stars do not," Joseph Smidt, a researcher at the theoretical design division of Los Alamos National Laboratory and the first author on the new work, said in a statement. "We asked, what if we could find a place where stars could grow much faster, perhaps to the size of many thousand suns; could they form supermassive black holes in less time?"

    The researchers compared their models to the most distant known energetic galactic center, called a quasar, and one of the most massive of those objects, which is also ancient, to see whether that method could have quickly grown them to full size. If ultralarge stars are born in the right environment — one with the ideal combination of rapidly incoming material and local conditions — they could indeed collapse and form quasars of that mass and age, the researchers found.

    The simulation also ended up accurately modeling star formation and other phenomena that happen around black holes, the distribution of galaxy densities, gas temperature changes and ionization, the researchers said in the statement.

    A new simulation from Los Alamos National Laboratory suggests how supermassive black holes might have formed extra quickly in the early universe.

    "This was largely unexpected," Smidt said. "I thought this idea of growing a massive star in a special configuration and forming a black hole with the right kind of masses was something we could approximate, but to see the black hole inducing star formation and driving the dynamics in ways that we've observed in nature was really the icing on the cake."

    The new work has been submitted to The Astrophysical Journal, and it is currently available online at arXiv.org.
