China on track to the first-ever landing on the ‘dark side’ of the moon
China on track to the first-ever landing on the ‘dark side’ of the moon
China has made plans to launch a satellite Sunday with an ambitious goal of being the first nation to land on the ‘dark side’ of the moon.
The mission involved in the satellite launch is known as Change-4. The satellite, known as the Queqiao relay satellite, will be launched to Lagrange L2 Point where it will be able to communicate with the Earth and the far side of the moon. This is important regarding phase 2 of the mission, which is landing on the moon at a destination furthest away from Earth.
China Plans to be the First Nation to Land on the Dark Side of the Moon
Here's the launch trajectory, taking the Queqiao Chang'e-4 relay sat to the second Earth-Moon Lagrange point via a lunar swing-by, and reaching it's destination in around 8-9 days.
This is significant because we never get to view this side of the moon due to the moon being tidally locked to Earth. This tidal lock is important because it prevents direct communication. Change-4 is anticipated to change this.
Queqiao was developed by the Chinese Academy of SpaceTechnology (CAST). Communication will be attainable for Queqiao on both the moon and the Earth at an orbit in between 65,000km and 80,000km beyond the moon. This location is desired because it is considered a gravitationally stable spot in orbit.
The Netherlands Chinese Low-Frequency Explorer (#NCLE) successfully passed the last assessment by the Chinese space agency! The instrument will be launched on board the Chinese Chang'e 4 relay satellite to a position behind the Moon in May. @RadRadioLab@isis_space
Queqiao, weighing in at 425kg, will be put in the position roughly six months before its’ landing mission to test its’ functionality. Additionally, Queqiao will be carrying the Netherlands-China Low-Frequency Explorer with a purpose of finding radio signals from the early days of our universe.
Queqiao is scheduled for a May 21st lift off at 5 am eastern standard time. The launch window consists of three days. The lander and rover for the Change-4 mission were initially manufactured at the same time as the Change-3 spacecraft that landed on the moon in 2013. This was done intentionally so a backup mission for Change-4 could be initiated in case issues arise.
Change-4 is the fifth mission for China. If everything works out with the mission, China plans to put people on the lunar surface within the next twelve years.
This footage was captured on the 20th of May 2018. It was captured by a drone that carried a 4K camera. The object seems to flying over a populated area. The object looks like a small silver disc that is hoovering above the area. The camera operator only noticed the object after he reviewed the footage.
It’s long been said that “If you want something done right, do it yourself.” How long? The quote is attributed to French playwright Charles-Guillaume Étienne in the early 1800s. The saying in French is “On n’est jamais servi si bien que par soi-même,” which translates literally to the more cumbersome “One is never served so well as by oneself.” Two hundred years later, the saying resonates stronger than ever, and now it’s becoming a driving force in the world of UFOs (see Tom DeLonge). Politico, the Washington DC-based political journal, recently began a website called POLITICO Space, a “weekly must-read briefing on the policies and personalities shaping the second space age.”
To launch POLITICO Space, Politico Defense Editor and Space writer Bryan Bender held an announcement panel discussion in mid-April. Joining him were fellow space Jaqueline Klimas, President and CEO of the Coalition for Deep Space Exploration Mary Lynne Dittmar and US Congressional Representatives Ami Bera (Democrat, California) and Randy Hultgren (Republican, Illinois). This was no space junket — Dittmar is an advisor President Trump on space policy and Bera and Hultgren are members of the House Committee on Science, Space, and Technology.
When you’re doing things yourself, you don’t let the opportunity to question space heavyweights and policy makers pass you by, so Bryan Bender referred to the Pentagon UFO revelations of last December and hit them with both barrels of his photon torpedo launcher:
“You hear these reports. We have been hearing them for decades from many credible people. Other countries take it more seriously. They have government researchers who, in the open, not in secrecy, try to explain the unexplainable. Should we be doing more? Or is this just crazy sci-fi stuff that is a waste of time?”
Talk about a loaded question! It would have been easy to deflect it (after all – they’re politicians) and move to what they really want to talk about (campaign donations), but Representative Bera gave a straightforward and unexpected answer.
“I’ve actually talked to the chairman of the subcommittee, Brian Babin, as well as Lamar Smith, the chairman of the full committee. I said we ought to have a hearing on this, right? We ought to bring some folks in. Look, if you want to boost our C-SPAN ratings, a lot of people would be really interested. We don’t know what these phenomena are. Obviously, it’s important enough to allocate some funds and we ought to talk about what we can talk about.”
Bera said the magic word … “funds.” Spending money shows he’s serious. And he wants to put it on TV, which should get the president interested. Republican Hultgren agrees.
“It definitely piques interest. It gets people engaged.”
We’re already piqued and engaged — it’s time for Congress to catch up. Will government money really get allocated and spent on opening up secret files and getting new UFO research started? Will the discussions be held out in the open on C-SPAN? (Would they get more viewers on Netflix?)
Representatives Bera and Hultgren have committed and they name-dropped Brian Babin and Lamar Smith – both Republicans from Texas. Smith is retiring so Babin better get onboard. He doesn’t have to worry about the 2018 election because his only opponent is the Green Party candidate (which in Texas means he’s running unopposed). Will they follow through? Expect POLITICO to keep reminding them.
And a special thanks to POLITICO Space for reminding us once again:
“If you want something done right, do it yourself.”
Areas in the US Where You’ll Most Likely See A UFO
Areas in the US Where You’ll Most Likely See A UFO
One of the most bizarre reported UFO sightings took place in North Carolina, which has had 7,570 reported sightings of unidentified flying objects since 1940. So odd that some of the UFO sightings inspire conspiracy theories of secret military experiments that have been going on in the state.
But what could be the chances to spot a UFO right now in either of Carolinas?
Statisticians at Casino.org had finally figured that out. They divided the reported sightings in each year throughout the past 78 years into the overall population.
It turns out that North Carolina has had a 1 in 135,000 chance of seeing a UFO after stepping out the door. Meanwhile, South Carolina faces a 1 in 117,300 chance with its 4,285 sightings, according to Casino.org.
When it comes to the number of actual UFO reports, North Carolina is one of the top 10 states with several reports recently in Lake Norman area and Charlotte, says National UFO Reporting Center in Davenport, Wash.
However, the calculations done by Casino.org are not based on the number of actual UFO reports as they are based on the population of the state. The smaller the community, the higher the odds.
One of the examples of Casino.org calculations is California, which has had 23,419 reported sightings, but with its vast population, people have a 1 in 168,700 chance of seeing a UFO in the state.
Among the 50 states in the Casino.org list, North Carolina was ranked at 16 and South Carolina at 21.
People are most likely to see a UFO in Wyoming, Vermont, Montana, North Dakota, and Alaska.
So, were aliens busier on earth in the 40s and 50s, or are they just better covered up now? Here's a graph to help you see just how common UFO sightings have been in the US for the last 80 years.
ESA ziet heftige laserstralen uit ruimtenevel schieten

Het wijst erop dat in het hart van de nevel wat verborgen zit.
Wie denkt aan aliens, heeft het mis. Volgens ESA ontstaat de laseremmissie doordat in deze planetaire nevel niet één, maar twee sterren te vinden zijn.
Miernevel Astronomen ontdekten de laseremissie met behulp van ruimtetelescoop Herschel. De emissie is afkomstig uit het hart van de Miernevel. Dit is een planetaire nevel die ontstaan is nadat een ster de handdoek in de ring heeft gegooid (zie kader).
Wanneer een niet al te zware ster (zoals onze zon bijvoorbeeld) door zijn brandstof heen is, stoot deze zijn buitenste lagen de ruimte in. Zo ontstaat rond de kern van de ster – die aangeduid wordt als een ‘witte dwerg’ – een vaak spectaculaire planetaire nevel.
Gas De laseremissie die Herschel heeft opgemerkt, suggereert dat rond de witte dwerg die zich in het hart van de planetaire nevel bevindt, veel gas te vinden is. De dichtheid van dat gas zou zo’n 10.000 keer hoger liggen dan in de twee ‘kwabben’ van de Miernevel. Dat is op het eerste gezicht vreemd: het gebied nabij een witte dwerg is doorgaans vrij leeg, doordat de stervende ster zijn buitenste lagen van zich heeft afgeduwd en gas dat daarbij is achtergebleven al spoedig op de witte dwerg terug zal vallen. “De enige manier waarop gas dicht bij de ster kan blijven, is door er in een schijf omheen te draaien,” vertelt onderzoeker Albert Zijlstra. De laseremissie wijst er dan ook op dat in de Miernevel zo’n gasschijf te vinden is en Herschel kijkt tegen het randje van die schijf aan. “Die oriëntatie versterkt het lasersignaal,” aldus Zijlstra.

(STScI / AURA).
Niet alleen De aanwezigheid van de schijf wijst er sterk op dat de witte dwerg in de Miernevel niet alleen is: de stervende ster moet bijna wel deel uitmaken van een dubbelstersysteem. “Want het is moeilijk om uitgestoten gas in een omloopbaan te dwingen, tenzij er een tweede ster is die het gas in de juiste richting duwt.” Het is astronomen nog niet gelukt om de tweede ster te spotten. Maar ze denken dat de massa die de stervende ster afstaat door die tweede ster wordt afgevangen en vervolgens in een schijf wordt gedwongen waarin het lasersignaal gegenereerd wordt.
Hoe het ook precies zit: het is een spectaculaire ontdekking. In de ruimte hebben onderzoekers op verschillende golflengtes en onder specifieke omstandighden nog maar enkele malen sterk gefocuste straling ontdekt. En er zijn slechts een paar kosmische ‘infraroodlasers’ bekend.

In 2017, several news organizations revealed the existence of the Advanced Aviation Threat Identification Program (AATIP), a U.S. government funded investigation into unidentified flying objects from 2007 to 2012. This secret $22 million program, however, was not the first of its kind. In fact official government UFO studies began in the 1940s with Project Sign providing some of the most credible videos of aerial phenomenon to date. The 2017 revelation that the U.S. government was actively researching UFOs reignited world interest in UFOs and aliens. Let’s revisit five of the most believable UFO sightings of the 21st century.
1. The Lights Above the New Jersey Turnpike (2001)
It takes a lot for motorists to stop alongside a highway to look towards the sky, but on July 14, 2001, drivers on the New Jersey Turnpike did just that. For around 15 minutes just after midnight, they marveled at the sight of strange orange and yellow lights in a V formation over the Arthur Kill Waterway between Staten Island, New York, and Carteret, New Jersey. Cataret Police Department’s Lt. Daniel Tarrant was one of the witnesses, as well as other metro area residents from the Throgs Neck Bridge on Long Island and Fort Lee, New Jersey near the George Washington Bridge. Air traffic controllers initially denied that any airplanes, military jets or space flights could have caused the mysterious lights, but a group known as the New York Strange Phenomena Investigators (NY-SPI) claimed to receive FAA radar data that corroborated the UFO sightings of that night.
2. The USS Nimitz Encounter (2004)
On November 14, 2004, the USS Princeton noted an unknown craft on radar 100 miles off the coast of San Diego. For two weeks, the crew had been tracking objects which appeared at 80,000 feet and plummeted to hover right above the Pacific Ocean. When two FA-18F fighter jets from the USS Nimitz arrived in the area, they first saw what appeared to be churning boiling water in an oval shape underneath the surface. Then, in a few moments, a white Tic Tac-like object appeared above the water. It had no visible markings to indicate an engine, wings, or windows, and infrared monitors did not reveal any exhaust. Commander David Fravor and Lt. Cmdr. Jim Slaight of Strike Fighter Squadron 41 attempted to intercept the craft, but it accelerated away, reappearing on radar 60 miles away—it moved three times the speed of sound and twice the speed of the fighter jets. This encounter was one of the stories reported along with the news of AATIP.
3. O’Hare International Airport Saucer (2006)
Flight 446 was getting ready to fly to North Carolina from Chicago’s O’Hare International Airport, when a United Airlines employee on the tarmac noticed a dark grey metallic craft hovering over gate C17. That day, November 7, 2006, a total of twelve United employees, and a few witnesses outside the airport, spotted the saucer-shaped craft around 4:15 p.m. The witnesses say it hovered for about 5 minutes before shooting upward where it broke a hole in the clouds, enough that the pilots and mechanics could see the blue sky. The news report became the most read story on Chicago Tribune’s website to that date and made international news. However, because the UFO was not seen on radar, the FAA called it a “weather phenomenon” and declined to investigate.
4. The Stephenville Sightings (2008)
The small town of Stephenville, Texas 100 miles southwest of Dallas, is mostly known for its dairy farms, but in the evening of January 8, 2008, dozens of its residents viewed something unique in the sky. Citizens reported seeing white lights above Highway 67, first in a single horizontal arc and then in vertical parallel lines. Local pilot Steve Allen estimated that the strobe lights “spanned about a mile long and a half mile wide” traveling about 3,000 miles per hour. No sound was reported. Witnesses believed the event was reminiscent of the Phoenix Lights sightings of 1997. While the U.S. Air Force revealed weeks later that F-16s were flying in the Brownwood Military Operating Areas (just southwest of Stephenville), many townspeople didn’t buy that explanation, believeing that what they saw was too technologically advanced for current human abilities.
5. East Coast GO FAST Video (2015)
Leaked in 2017 along with the news of the Advanced Aviation Threat Identification Program, was a video that revealed an encounter between an F/A-18 Super Hornet and an unidentified flying vehicle. Seen along the East Coast on a Raytheon Advanced Targeting Forward-Looking Infrared (ATFLIR) Pod, the craft was similar to that spotted off San Diego in 2004: It was a fast-moving white oval about 45-feet-long without wings or exhaust plume. The pilots tracked the object at 25,000 feet above the Atlantic Ocean as it flew away and simultaneously rotated on its axis. Whether the vehicle was a product of another country’s technology or alien airship remains a mystery.

Weird Space Rock Provides More Evidence for Mysterious 'Planet Nine'
Weird Space Rock Provides More Evidence for Mysterious 'Planet Nine'
By Elizabeth Howell, Space.com Contributor
The solar system just got a bit stranger. As astronomers continue their ongoing quest to find the elusive Planet Nine, a team found a space rock that lends credence to the idea that a huge super-Earth planet really exists in the outer reaches of our solar system.
The newfound asteroid, called 2015 BP519, adds to a growing body of evidence about little worlds in the solar system being perturbed by something big. Astronomers detailed its discovery and description in a new paper, adding that the bizarre angle of its orbit gives more weight to the idea that a big planet is out there — somewhere — tugging on the asteroid's path around the sun.
"We also consider the long term orbital stability and evolutionary behavior within the context of the Planet Nine hypothesis, and find that 2015 BP519 adds to the circumstantial evidence for the existence of this proposed new member of the solar system," read the abstract of the paper, which is available now on preprint website Arxiv and has been submitted to The Astronomical Journal. [How Astronomers Could Actually See 'Planet Nine']
Following up on the discovery,Quanta Magazine recently published an articlesurveying several astrophysicists who specialize in studying small worlds, including the discoverers of 2015 BP519. While not everybody agreed that Planet Nine was responsible for the strange orbit, the overwhelming majority agreed the new discovery gives more credence to the idea. "The second you put Planet Nine in the simulations, not only can you form objects like this object, but you absolutely do," lead author Juliette Becker, a graduate student at the University of Michigan, told Quanta. (You can look at the object's orbit onlinehere.)
It's not the first time Planet Nine was blamed for pushing an object around. Back in 2014, before Planet Nine was officially hypothesized, astronomers Scott Sheppard and Chadwick Trujillo noticed orbital irregularities in several small bodies beyond Neptune's orbit. These included dwarf planet Sedna, a newfound object called 2012 VP113, and several other trans-Neptunian objects (TNOs).
Then, in January 2016, astronomers Konstantin Batygin and Mike Brown saw more evidence of TNOs with perturbed orbits. They were the ones who first gave "Planet Nine" a name, size and distance. They suggested that the mysterious planet could be 10 times more massive than Earth, located 600 astronomical units (AU) from the sun. (One AU is the average distance between the Earth and the sun, which is 93 million miles or 150 million kilometers.)
A flood of studies followed about TNOs and how Planet Nine might have affected their orbits; the following summary is just a sampling. Not all teams were enthusiastic, with one group from the Outer Solar System Origins Survey (OSSOS) cautioning that many of these surveys could be just observational bias.
But astronomers persisted, with Sheppard and Trujillo discovering at least two new TNOs possibly affected by Planet Nine. Another study showed Planet Nine perhaps influenced the tilt of planets in our solar system. And in 2017, astronomers from the University of Madrid in Spain found peculiarities in the orbits of 22 "extreme" TNOs that orbit the sun that could also be explained by a large, distant body exerting gravitational influence. (These TNOs never get closer to the sun than Neptune — which is 30 AU away, orbiting the sun in a rough circle — and have an average distance of at least 150 AU.)
By October 2017, Batygin said, there were at least five different lines of evidence that suggest the existence of the planet. "If you were to remove this explanation and imagine Planet Nine does not exist, then you generate more problems than you solve. All of a sudden, you have five different puzzles, and you must come up with five different theories to explain them," he said in a statement.
The Alien Observatory: "Signals of Extinct Extraterrestrial Civilizations --Echo Throughout the Milky Way"
The Alien Observatory: "Signals of Extinct Extraterrestrial Civilizations --Echo Throughout the Milky Way"
“The signals will be from the civilization as it was,” said Frank Drake, creator of the famous Drake Equation. “It is not a remote possibility — it is a high probability — that signals we receive will be from a "civilization that no longer exists.”
If signals from an alien civilization ever reach Earth, odds are the aliens will already be dead. In an effort to update the 1961 Drake Equation, which estimates the number of detectable, intelligent civilizations in the Milky Way, physicist Claudio Grimaldi and colleagues calculated the area of the galaxy that should be filled with alien signals at a given point in time.
“If the civilization emitted from the other side of the galaxy, when the signal arrives here, the civilization will already be gone,” says physicist Claudio Grimaldi, of the Federal Polytechnical School of Lausanne in Switzerland.
The team, reported Science News and Mercury News, which includeed Frank Drake (now a professor emeritus at the SETI Institute in Mountain View, Calif., and the University of California, Santa Cruz), assumed technologically savvy civilizations are born and die at a constant rate. When a civilization dies out and stops broadcasting, the ghostly signals it had sent continue traveling like concentric ripples on a pond.
Electromagnetic signals (blue circles) from alien civilizations shown in the image above will continue traveling through the Milky Way even after the aliens are gone. The appearance of a doughnut hole represents when a civilization dies out.
Scientists gathered at the SETI Institute in Mountain View, California this past March to chart new approaches to answering the question: are we alone? The conference, titled “Decoding Alien Intelligence”, sought to broaden perspectives and expand the methodologies applied in the effort to detect extraterrestrial technology:
“New tools are available that can enable this approach and help us decipher the evolutionary and probabilistic nature of advanced alien life,” said organizer and SETI Institute Director Nathalie Cabrol. “We can build a new roadmap that is multidisciplinary, that opens the toolbox.”
A recently released update to the Drake Equation – a framework for discussing the probability of intelligent life existing beyond Earth – is receiving a fair bit of media buzz. The Drake equation was developed during the outset of the modern SETI field to act as a framework for the scientific community to discuss the probability of advanced extraterrestrial life. The probabilistic argument was devised by pioneer in the search for extraterrestrial intelligence, Dr. Frank Drake, who participated in the new study.
According to the study, if advanced aliens exist on the furthest edge of the galaxy from us, any signals traveling at the speed of light will not reach us for quite some time. Any signals that do reach our planet will likely be vestiges of a long dead civilization.
“The signals will be from the civilization as it was,” said Drake. “It is not a remote possibility — it is a high probability — that signals we receive will be from a civilization that no longer exists.”
There’s the chance that it’s still alive “but no longer be transmitting,” Drake said. “Or it may have changed in a very big way, such as migrating from the planet to escape its expanding star.”
Senior astronomer at the SETI Institute, Seth Shostak, still sees the value in collecting such a message: “To me, it is like finding a bottle on a beach with a note in it,” said Shostak. “It may be that whoever put the note in is long gone. But at least you know there’s somebody on the other side of the world.”
It’s important to remember that determining the longevity of a potential alien race based on the still-developing example of our own survival has a limited value, as SETI Institute's Andrew Fraknoi points out: “Until we know more about our longevity, it is pure guesswork,” he said. “Every year we don’t destroy ourselves, we add one more year to what we know civilizations can do.”
If the civilization lasted less than 100,000 years — the time it takes light to cross the galaxy — then the odds of the signals reaching Earth while the civilization is still broadcasting are vanishingly small, the researchers reported February 27 at arXiv.org. Humans, for example, have been transmitting radio waves for only about 80 years, so our radio waves cover less than 0.001 percent of the Milky Way.
Surprisingly, the team also calculated that the average number of E.T. signals crossing Earth at a given time should equal the number of civilizations currently transmitting — even if the civilizations we hear from aren’t the same ones presently broadcasting. Grimaldi is now working on a paper about what it means that we’ve found none so far.
China is taking its first steps towards the dark side of the Moon.

The Chinese space agency is paving the way for its unmanned Moon landing. On Monday, the China Aerospace Science and Technology Corporation launched a Long March 4C rocket from the Xichang Satellite Launch Center. The launch, which delivered relay satellite Queqiao (Magpie Bridge), wasn’t broadcasted but went smoothly, says state news outlet Xinhua.
To boldly go
“The launch is a key step for China to realize its goal of being the first country to send a probe to soft-land on and rove the far side of the Moon,” Zhang Lihua, manager of the relay satellite project, told Xinhua.
Roughly 25 minutes after the launch, the 425kg Queqiao spacecraft separated from the rocket’s upper stage and aimed toward a halo orbit of the Earth-Moon Lagrange Point L2. It will spend the next six months undergoing tests to ensure that all onboard systems are running smoothly in preparation for its mission — relaying messages between ground control and the dark side of the Moon.
If Queqiao proves itself reliable, China will move forward with the launch of the Chang’e 4 spacecraft, scheduled for later this year. The mission — humanity’s first attempt to land on the far side of the Moon — will also include a rover intended to explore any areas of interest around the landing site.
Because the Moon’s body lies between Earth and the landing site, Queqiao will need to fly overhead and beam messages between the rover and mission control.
Apart from this, Queqiao will also carry two onboard instruments: a Dutch radio antenna, intended for the study of celestial radio signals blocked by Earth’s atmosphere, and a large-aperture laser angle reflector to measure the range between Earth and the spacecraft.
Queqiao should reach its L2 halo orbit in about eight days — fingers crossed for the little guy.
If you’ve been following the science news, you’re probably aware of the new study claiming octopuses come from outer space. “Octopuses are from space, scientists say” was one of the catchy headlines published in Australia, while The Express wrote that“Octopuses came to Earth from space as frozen eggs millions of years ago”. These aren’t two cherry-picked instances, the internet was abuzz with variations on the same theme. Unfortunately, however, this is almost certainly not the case. Let’s see what really happened.
What the study says
The new study, penned by over 30 researchers, essentially rehashes the theory of panspermia — the idea that life on Earth emerged in outer space, hitching a ride on meteorites or other objects that crashed into Earth at one point, something often referred to as the Hoyle-Wickramasinghe (H-W) thesis of cosmic biology.
The research starts from the Cambrian Explosion an event approximately 541 million years ago, during an age called the Cambrian period. The Cambrian Explosion was an age of extreme diversification of life, during which most major animal phyla started to emerge. The study’s authors question whether that happened naturally, with just the elements existing on Earth.
“One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. Such viruses are known to be plausibly associated with major evolutionary genomic processes. We believe this coincidence is not fortuitous but is consistent with a key prediction of H-W theory whereby major extinction-diversification evolutionary boundaries coincide with virus-bearing cometary-bolide bombardment events,” the study reads.

In other words, what they’re saying is that life didn’t just emerge on its own, it was “seeded” from life-bearing comets that pummeled our planet at various times throughout history. These comets could have brought a myriad of novel life-forms from other planets, including viruses. This is one of the main assumptions of the H-W thesis — that small bodies such as asteroids and comets can protect the “seeds of life”, including DNA and RNA. So far, so good; this is a plausible idea, that has been investigated since the 1970s and continues to be analyzed by various groups. There’s not much evidence to say that it did happen, but with what we know so far, it might have happened.
Then, the authors make a big leap: if you’re not convinced by the panspermia theory, you need not look farther than the octopus. Octopuses have very complex nervous systems and big, specialized eyes — two unprecedented features.
“A second focus is the remarkable evolution of intelligent complexity (Cephalopods) culminating in the emergence of the Octopus,” the study continues.
This is where it starts to get thorny. Cephalopods, the group in which octopuses belong, did emerge in the Cambrian — the fossil records clearly suggest so. But the early cephalopods were Nautiloids, a very diverse group of creatures which exist to this day. But Nautiloids look completely different to octopuses, and they don’t share many of their impressive features. In fact, octopuses didn’t emerge until the Devonian, 323 million years ago. This means that there’s a window of over 200 million years from the Cambrian explosion to when the first true octopuses emerged, which is plenty of time to selectively develop specialized features (there are studies which say octopuses developed a bit earlier, but not significantly in this context).
Artistic depiction of Orthoceras — an early nautiloid.
Furthermore, when the octopus genome was mapped in 2015, it was shown that the nervous system genes split from the squid’s only around 135 million years ago — again, long after the Cambrian explosion. In all practicality, the evolution of the octopus was never really regarded as a mystery requiring additional explanation. This is an ancient group with some remarkable features, but these features didn’t appear in the earliest creatures, developing gradually over the course of hundreds of millions of years.
Occam’s Razor
Instead, what the new study suggests is that fertilized octopus eggs hitcher a ride aboard an icy comet and crashed into the sea at the onset of the Cambrian explosion. Alternatively, researchers write, an extraterrestrial virus infected a population of early squid, causing them to evolve in this unusual way. The genes responsible for the octopus evolution, they say, don’t appear to have come from their ancestors.
“The transformative genes leading from the consensus ancestral nautilus to the common cuttlefish to squid to the common octopus are not easily to be found in any pre-existing life form,” the study, published in Progress in Biophysics and Molecular Biology, claims.
“It is plausible then to suggest they seem to be borrowed from a far distant ‘future’ in terms of terrestrial evolution, or more realistically from the cosmos at large.”
Again, this is technically possible. It might have happened. But that doesn’t mean it did. Occam’s razor suggests that the simpler explanation is usually the better, and this is probably the case here — there’s no reason to go and speculate about extraterrestrial origins.
It’s noteworthy that in his review of the paper, medical researcher Keith Baverstock from the University of Eastern Finland, concedes that there’s a lot of evidence that plausibly aligns with the H-W thesis, such as the curious timeline of the appearance of viruses — and yet, herein lies the problem: plausibility does not mean probability. Basically, just because something can happen doesn’t mean it did. The new paper goes to great lengths to prove that it could happen, and to open some interesting discussions. Make no mistake, this is not an amateurish study published in a predatory journal. However, the scope of the paper is oversold, and as Ken Stedman, a virologist and professor of biology at Portland State University, told Live Science, the authors didn’t carefully review existing literature, and they make extremely speculative claims.
Of course, mainstream media was all over this. The idea that life on Earth came from outer space is terribly appealing — particularly when we’re talking bizarre creatures like octopuses, and everyone gasped at the idea of an alien octopus. Unfortunately, that’s probably not the case. Octopuses are fascinating creatures, and I hope we can cherish them even if they’re not aliens.

The immigrant in case is an asteroid. Currently nestled in Jupiter’s atmosphere, it’s the first interstellar object that resides in our solar system.

Not a tourist
Last year, a different asteroid made headlines after it became the first interstellar object we’ve found in our solar system. But that was just a tourist, a passer-by — whereas this new asteroid, given the catchy name 2015 BZ509, is here to stay.
We’ve seen the object for quite some time, but its origin was only now explained. All the planets (and most of the other objects) in our solar system rotate around the Sun in the same direction — but 2015 BZ509 is different: it moves in the opposite direction, something called a ‘retrograde’ orbit.
“How the asteroid came to move in this way while sharing Jupiter’s orbit has until now been a mystery,” explains Dr Fathi Namouni, lead author of the study. “If 2015 BZ509 were a native of our system, it should have had the same original direction as all of the other planets and asteroids, inherited from the cloud of gas and dust that formed them.”

Namouni and his colleagues used the current orbit of the asteroid to extrapolate its whereabouts and movement 4.5 billion years ago — during the early age of our solar system, when planets were still forming. They found that even then, 2015 BZ509 was moving the same way — meaning that it couldn’t have possibly formed in our solar system, and instead came from somewhere else.
In other words, 2015 BZ 509 emigrated from its parent star and settled around the Sun in a similar environment.
“Asteroid immigration from other star systems occurs because the Sun initially formed in a tightly-packed star cluster, where every star had its own system of planets and asteroids,” comments Dr Helena Morais, the other member of the team. “The close proximity of the stars, aided by the gravitational forces of the planets, help these systems attract, remove and capture asteroids from one another.”
The finding isn’t just remarkable in itself, but also sheds some important light on how our solar system form, and perhaps, how life itself emerged. Understanding exactly how and when 2015 BZ509 arrived and settled in the Solar System provides clues about the Sun’s original star nursery, and about the potential enrichment of our early environment with components necessary for the appearance of life on Earth.
The article “An interstellar origin for Jupiter’s retrograde co-orbital asteroid”, by F. Namouni & H. Morais, was published in the Monthly Notices of the Royal Astronomical Society: Letters (2018), in press (DOI: 10.1093/mnrasl/sly057).
In the school scene in Alfred Hitchcock’s terrifying 1963 classic, The Birds, a flock of black birds rapidly multiplies, steadily filling a spooky, silent playground. Imagine that, but multiply it by thousands and whip it into a swirling funnel hundreds of feet high. That’s what an intrepid photographer captured in the stormy sky over a placid countryside in an otherworldly photo posted to Reddit’s r/WTF thread this week. The photo has been dubbed by at least one useras a “birdnado.”
Unlike the premise of Sharknado, however, this is not a flock of birds unwittingly swept up into an actual tornado. Rather, it’s far more likely to be a flock of thousands of starlings flying together in a formation known as a murmuration.
Starlings, birds common to North America and Europe, are famous for forming immense flocks, sometimes containing up to 4 million individuals. Despite their otherworldly appearance, murmurations form naturally through an oddly specific organizational mechanism that scientists laid out in a 2013 PLOS Biologypaper.
Murmurations, the scientists write, are made possible by an individual starling’s ability to track the movements of exactly seven of their neighbors at any one time while flying in a flock. In the past, scientists had already determined that flock formation is beneficial for birds for a number of reasons, like easing the amount of energy required to travel and offering protection from predators. But the nature of how a flock forms — and stays together — was not clear. The team, focusing on starlings, knew that the birds had to strike a “balance between group cohesiveness and individual effort.”
The starlings in this birdnado manage to stay together because focusing on only the six or seven individuals in their immediate vicinity allows them to optimally “manage uncertainty” in highly uncertain environments. In other words, if a random disturbance causes the flock to shift suddenly, the flock will be optimally cohesive if every member pays attention to only the movements of its six or seven closest neighbors.
The birdnado may not be an actual natural disaster, but it can certainly be considered a storm — especially to the people who have to clean up the copious amounts of shit they’re known to leave behind. As Inversereported previously in an article on murmuration, starling guano has proven to be especially hard to deal with in Rome, where they are known to pass through:
The biggest issue is that they poop everywhere, covering streets, buildings, Vespas, and trees with thick layers of foul guano. Since the starlings feast in the copious olive groves outside of Rome, their poop is also especially oily.
Fortunately, in this apocalyptic photo, the birdnado seems to be forming over some desolate-looking fields. It’s scary-looking stuff, but fortunately, it’s far less threatening than actual tornados — though the mess it leaves in its wake likely smells far worse.
Scientists have reported the discovery of a “Trans-Neptunian object” whose orbital movements are highly unusual. Researchers suggest this strangely behaving rock could be orbiting a larger planet in deep space, bringing astronomers one step closer to finding Planet Nine.
A team of astronomers representing 35 universities and institutions announced the detection of the mystery rock this week, dubbed 2015 BP519, and have observed its eccentric orbital stability with new insight. The researchers published their dynamical analysis this week and describe the mystery rock within the context of the Planet Nine Hypothesis. The published data suggests that 2015 BP519 “adds to the circumstantial evidence for the existence of this proposed new member of the Solar System.”
The team, led by Juliette Becker of the University of Michigan, discovered 2015 BP519 by using data from the Dark Energy Survey, an ongoing project that seeks to map parts of space beyond what is known. The team had not expected to find orbiting objects in the data, let alone an object that orbits at a different angle than the known eight planets in the Solar System.
Whereas the known planets move along the same orbital plane due to the sun’s gravitational pull, Becker’s team says 2015 BP519 is tilted 54 degrees from that plane. This could mean that the object is influenced by a separate gravitational pull, such as a giant “ghost planet” that 2015 BP519 orbits much like a planet’s moon.
Astronomers have been searching for Planet Nine since early 2016, when astronomers Konstantin Batygin and Michael Brown from the California Institute of Technology found a group of distant objects orbiting the sun at an axis different from the known planets. These Kuiper Belt Objects (KBOs) created eccentric orbital patterns, leading Batygin and Brown to suggest they were being pulled by something much larger than Earth and lurking somewhere farther from the sun than Neptune.
Becker’s paper expounds on these concepts and presents new data to support the Planet Nine Hypothesis, but will still need to be peer-reviewed and formally published. While the strange orbital behavior of 2015 BP519 may not confirm the existence of Planet Nine just yet, it offers a glimpse of how little is known about deep space and will serve as an asset to the scientists actively looking for the contested ghost planet.
WETENSCHAP In sciencefictionfilms worden al tientallen jaren herinneringen getransplanteerd. Nu zijn wetenschappers er voor het eerst echt in geslaagd bij slakken.
Amerikaanse onderzoekers konden herinneringen van de ene slak transplanteren naar een andere door ribonucleïnezuur (RNA), een vorm van genetische informatie vergelijkbaar met DNA, uit het zenuwstelsel te halen en over te plaatsen.
Een eerste groep Californische zeehazen, een soort zeeslak, was getraind om een verdedigingsreactie te ontwikkelen. De wetenschappers gaven de diertjes lichte elektroshocks aan de staart, waarop de slakken in elkaar doken. Als de onderzoekers de slakken vervolgens een tikje gaven, deden ze hetzelfde en bleven ze gemiddeld zo’n 50 seconden ineengedoken liggen. Bij de slakken die niet getraind waren, duurde dat amper een seconde.
Na de ingreep waarbij het RNA uit het zenuwstelsel van de eerste groep slakken werd overgeplaatst naar de niet-getrainde slakken, gedroegen die laatsten zich echter alsof ze hetzelfde proces ondergaan hadden. Na een tikje van de onderzoekers doken ze in elkaar en bleven zo gemiddeld 40 seconden liggen.
Een gelijkaardig effect werd vastgesteld wanneer de onderzoekers hun studie herhaalden met sensorische zenuwcellen in een petrischaaltje.
Geheugenonderzoek
Onderzoeker David Glanzman van de universiteit van Californië in Los Angeles (UCLA), die benadrukt dat de slakken tijdens het experiment geen pijn voelden, zegt dat het is “alsof we het geheugen van de slakken hebben getransplanteerd”. De studie, die gepubliceerd is in het vakblad eNeuro, kan nieuwe inzichten verschaffen over het geheugen. Meestal wordt aangenomen dat lange-termijnherinneringen opgeslagen worden in de synapsen in de hersenen, de verbindingspunten tussen zenuwcellen. “Maar dan zou ons experiment nooit hebben kunnen werken”, zegt Glanzman. De UCLA-professor heeft een eigen theorie, namelijk dat herinneringen worden opgeslagen in de kern van zenuwcellen en dat RNA een rol speelt bij geheugenvorming.
‘Het is alsof we het geheugen van de slakken hebben getransplanteerd’
David Glanzman, onderzoeker
Volgens de onderzoekers zijn de cellen en moleculaire processen bij zeeslakken vergelijkbaar met die van mensen, al heeft de slak ongeveer 20.000 zenuwcellen in zijn centraal zenuwstelsel en de mens zo’n 100 miljard. Dat het onderzoek daadwerkelijk zal leiden tot geheugentransplantaties bij mensen, is echter klein. De onderzoekers zien deze resultaten eerder als een belangrijke stap in het onderzoek naar ziektes als alzheimer en post-traumatisch stresssyndroom.

Al gehoord van ‘laze’? Lava bereikt kust van Hawaï en dat leidt tot nieuw gevaar - HLN.be
Al gehoord van ‘laze’? Lava bereikt kust van Hawaï en dat leidt tot nieuw gevaar -HLN.be

Lava stroomt de oceaan in.
MILIEUDe autoriteiten van Hawaï maken zich grote zorgen over de hete lavastromen van de uitgebarsten vulkaan Kilauea. Die hebben intussen de Stille Oceaan bereikt en dat brengt een nieuw gevaar met zich mee. Wanneer de lava in contact komt met het koude water, ontstaat namelijk een schadelijk product.
De combinatie wordt in het Engels ‘Laze’ genoemd, een samentrekking tussen ‘lava’ en ‘haze’ (nevel). Het gaat om een bijtend product, waarbij zoutzuurgas en vulkanische gasdeeltjes in de lucht terechtkomen.
Het product kan irritatie veroorzaken aan de longen, de ogen en de huid. Bij een vorige uitbarsting in het jaar 2000 kwamen zelfs twee mensen om het leven door de lavanevel. De inwoners van het eiland krijgen daarom de raad om zo ver mogelijk weg te blijven van plaatsen waar lava de oceaan instroomt.
Lava op been
De vulkaan Kilauea, een van de meest actieve vulkanen ter wereld, liet al een spoor van vernieling achter. Tientallen huizen werden opgeslokt en nog tientallen andere worden bedreigd.
Intussen is ook sprake van één zwaargewonde. Een man kreeg een klonter lava op zijn been toen hij op zijn balkon zat. De lava kwam terecht op zijn scheenbeen, en verbrijzelde alles vanaf daar tot onderaan zijn been. De man werd naar het ziekenhuis gebracht.

Tot wel 8000 buitenaardse megastructuren in het heelal. Deze astronomen speuren naar raadselachtige Dysonbollen
Tot wel 8000 buitenaardse megastructuren in het heelal. Deze astronomen speuren naar raadselachtige Dysonbollen
Een team astronomen heeft aanwijzingen gevonden dat er in het heelal tot wel 8000 buitenaardse megastructuren rond verre sterren zijn gebouwd.
Ze analyseerden gegevens die zijn verzameld door ruimtesonde Gaia van de Europese ruimtevaartorganisatie ESA en vonden mogelijke tekenen van enorme structuren die Dysonbollen worden genoemd.
Deze Dysonbollen zouden worden gebouwd om energie aan sterren te onttrekken.
Meerdere zoektochten
Astronomen van de Universiteit van Uppsala in Zweden en de Universiteit van Heidelberg in Duitsland schreven: “De energie kan vervolgens worden gebruikt voor supercomputers, het aandrijven van vaartuigen of lange-afstandscommunicatie.
De onderzoekers merken op dat er al meerdere zoektochten zijn opgezet naar Dysonbollen, maar dat ze nog niet zijn gevonden.
Het zou veel tijd in beslag nemen om zo’n enorm object te bouwen.
8000
De astronomen zochten niet naar één gigantisch object rond sterren, maar naar een zwerm satellieten, waarbij iedere satelliet een klein deel van de straling absorbeert.
Tijdens het analyseren van de gegevens stuitten ze op duizenden kandidaten, hoewel het onwaarschijnlijk is dat ze allemaal zijn gemaakt door een buitenaardse beschaving.
Volgens de wetenschappers voldoen 8000 van de onderzochte sterren aan de criteria om omringd te kunnen worden door een Dysonbol.
Meest interessante
Een ster genaamd TYC 6111-1162-1 bleek de meest interessante individuele kandidaat te zijn voor verder onderzoek, wat betekent dat de kans het grootst is dat daar een Dysonbol kan worden gevonden.
Eerder stelden astronomen dat het vreemde gedrag van de ster KIC 8462852 kon worden verklaard door een buitenaardse megastructuur.
In 2016, Google Maps – the gift that keeps on giving when it comes to images of things that look paranormal or jsut plain weird – gave the world a strange photograph of what appeared to be a round island in a slightly larger round body of water that appeared to circling around the edge in an unexplainable manner. That island in a remote Argentine forest was dubbed “The Eye” by Argentine producer and film director Sergio Neuspiller, who found it while looking for a location to shoot a horror movie about UFOs. Although locals were familiar with the site and reported seeing bright flashes of light emitting from it that they thought might be related to a nearby Indian burial ground, the film crew was unable to hack its way through the vegetation to view it firsthand. A Kickstarter program was set up to raise the money for an expedition. That was two years ago. This week, it was reported that “new studies” found that the circular island and pond could be an “extraterrestrial base.” Did Neuspiller make it through the jungle and meet some aliens?
“The phenomenon is real and would explain several of the supernatural stories connected with the presence of UFOs in the area and other paranormal aspects.”
UFO Spain seems to be the source of the story on what it claims are new studies and new talks of an extraterrestrial base. It includes a depiction of what the base might look like and the coordinates of The Eye (34 ° 15’07.8’S 58 ° 49’47.4 “W ) so anyone can see it on Goggle Maps for themselves. (To save you some time, here’s the link. You’re welcome.)
What’s a little jungle when you’re hunting for an ET base?
The Eye is clearly visible – as is the lack of any paths through the jungle leading up to it. No roads, no fallen trees, no machete-cut paths. It’s been two years since the discovery and the Kickstarter campaign. What happened?
$9,698 pledged of $50,000 goal 157 backers 0 seconds to go Funding Unsuccessful This project’s funding goal was not reached on October 10.
Cry for Argentina because it’s definitely not Hollywood, where $50,000 is not a movie budget, it’s a bar tab. Why were these filmmakers and their proposed team of scientists and ufologists unable to raise even 20% of the funding needed to make and film their expedition to The Eye? Is The Eye or whatever is behind it somehow preventing them from further investigation? And what were the “new studies”?
“The legends told by the residents of this area of Buenos Aires leave anyone who listens to them speechless. From stories of souls in pain that roam the surroundings, to lights of extraterrestrial ships that enter the island.”
Apparently, the “new study” consisted of talking to more people in the area to get their stories and opinions on The Eye. Really? Here’s a better idea. If you can raise $10,000, that sounds like enough to rent a helicopter and fly over The Eye. Maybe even dangle a camera directly over it or drop some instruments into it. If you’re that interested in The Eye, wouldn’t you try some other ways to poke a finger into it?
Unless you truly believe it’s an ET base based solely on native legends and fear that approach would be dangerous. Then again, is it any more dangerous than showing up on the ground armed with machetes?
This isn’t Antarctica … it’s Argentina. It’s time for a better examination of The Eye.
94-year-old mathematician and theoretical physicist Freeman Dyson is the mind behind many groundbreaking mathematical concepts and theoretical technologies related to harnessing the potential of outer space. Dyson proposed the Dyson tree, a genetically-engineered plant capable of growing inside a comet, producing a breathable atmosphere and allowing humanity to transform comets into natural space stations. Dyson is perhaps more famous for his Dyson sphere concept, a hypothetical megastructure which completely surrounds stars, harnessing 100% of its radiant energy. Such a structure was suspected in the strange saga of Tabby’s Star which played out throughout 2016 and 2017.
Still kickin’ out the jams at 94.
Dyson is back in the news this year with a new proposed technology the English-born visionary believes could seed life throughout the universe. Dyson calls his idea the “Noah’s Ark Egg” and describes it as a “way of making space colonies highly cost-effective.” In an interview with influential science fiction author Neal Stephenson and Robbert Dijkgraaf, Director of the theoretical research center Institute for Advanced Study, Dyson outlined his vision for sending the eggs out into the cosmos in order to spread the Earth’s biodiversity to distant exoplanets and speed up the colonization process:
The Noah’s Ark Egg is an object looking like an ostrich egg, a few kilograms in weight. But instead of having a single bird inside, it has embryos — a whole planet’s worth of species of microbes and animals and plants, each represented by one embryo. It’s programmed then to grow into a complete planet’s worth of life. So it will cost only a few million dollars for the egg and the launch, but you could have about 1,000 human beings and all the life support, and all the different kinds of plants and animals for surviving. The cost per person is only a few thousand dollars, and it could enlarge the role of life in the universe at an amazingly fast speed.
Dyson says the technology to design these “eggs” may only be a hundred years away or so, but that many advances in embryology and robotics are needed before the eggs could be developed.
As far-fetched as the idea might sound, more and more evidence points to the idea that life on Earth may have come from space. It’s no stretch, then, to assume that it }also work the other way. Could humans seed life throughout the universe using technologies similar to Dyson’s proposed Noah’s Ark Eggs? It makes me wonder: what if one of these eggs went through a wormhole in the future and is caught in a causal loop? Could we have seeded life on Earth ourselves from the future as our planet dies around us? Has this all happened before and will it all happen again?
Nah, probably not. We all know a wizard in the sky made us with his powerful magic. Now close your eyes and thank him for your Hamburger Helper before he sends down more cancer to punish us.
Fire in the sky: Multi-colored UFO cloud appears over São Paulo, Brazil
Fire in the sky: Multi-colored UFO cloud appears over São Paulo, Brazil
A rare sky phenomenon above the state of São Paulo, Brazil has delighted people.
The multi-colored glow appeared in the sky on May 19, 2018 and it was likely a fire rainbow, which occurs when sunlight refracts through ice-crystal clouds.
Others have said it could have been cloud iridescence, which happens when water droplets or crystals scatter light, or could it be an earthquake light? Anyway it remains a very strange phenomenon.
