Colorado witness says UFO about 2,000 off ground
Colorado witness says UFO about 2,000 off ground
A Colorado witness at Aurora reported watching a low flying triangle UFO with multiple lights, according to testimony in Case 79832 from the Mutual UFO Network (MUFON) witness reporting database.
Witness sketch.

The witness was outside in Babi Yar Park with four friends shooting a school video project at 11 a.m. on October 16, 2016, when the object was first observed.
“I looked up for some reason,” the witness stated.“I don’t know what caused me to, but when I did I saw an object. This object looked like a B-52 bomber, but it was dark and made no noise. The object had a leading edge of 10 lights with one in the center and four on the sides of the leading edge of the wings, and appeared to be black as if painted matte black.”
The witness first thought the object looked like a B-52 bomber. Pictured: Babi Yar Park.

The witness stated that the object was flying southwest about 2,000 feet off the ground.
“I’d say I couldn’t really tell due to clouds being in the sky and no reference points, but it was moving at around 300 mph. I asked my friends to look up and immediately three of the four saw the object. My other friend did not have his glasses with him, so he could not view the object, but did claim to see a blob in the sky flying.”
The object quickly moved away.
“After a period of 15 seconds after tracking since first seeing, the object made a shallow bank southward and disappeared into the night sky probably due to blending in with the night.”
Aurora is in Arapahoe and Adams counties, with the extreme southeastern portion of the city extending into Douglas County, population 325,078. Colorado Field Investigator Jeremy Ray 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.
Two UFOs Seen Passing Earths Moon, Military Formation, Space Wars? Oct 23, 2016, Video, UFO Sighting News.
Two UFOs Seen Passing Earths Moon, Military Formation, Space Wars? Oct 23, 2016, Video, UFO Sighting News
Date of sighting: Oct 23, 2016 Location of sighting: Earths Moon This video was recorded by Richard205Maria of Youtube, using their camera attached to a telescope. His editing software allows us to see its actual shape...a perfect saucer...two of them. There is no way these disks are satellites. First off, satellites wont be side by side for risk of crashing into on another and destroy each other. Second, we don't see any arms or solar panels to collect energy or transmit messages. Therefore, these are actual UFOs, flying in military style, because they are flying with a wingman, to keep each other out of possible trouble. These two...are prepared to fight, and that worries me. Please stop by Richard205Maria and give their video a thumbs up for support. Great work there. Scott C. Waring
Eyewitness states:
Here is an old video that I recorded last year and I'm coming back to take a closer look to those very strange objects. Thank you for watching and your time Rich
Here one interesting video of a group of bright lights hovering above Surf City in North Carolina.
Witness report:
My wife and I were sitting out on our deck around 11PM on August 27, 2016. We noticed a group of orange, glowing orbs from the northeast about 10 feet above the house across the street. They floated slowly and silently towards our direction. We noticed them because we were seated facing north, so you couldn’t miss them unless you were asleep. We both observed these object with a skeptics eye at first, but it was unlike anything we had ever seen before. They made absolutely no noise. There was no frame to them (like a Chinese lantern). We saw them from the side and from directly underneath. I rushed into the house, grabbed my camera and told my daughter to come see these objects. I exited our deck into the front yard and started filming. There was 5 of them. They were hovering just above the power lines. The objects were in a line, one behind the other. As they reached our house they moved into a circular formation. They hovered above our house for about 20-30 seconds before going back into a linear formation and moving on towards the southwest. My wife then noticed that a sixth orb was hovering just 5 or so feet above our house as if it was curious of us. That’s when my dog started to bark at the object. It hovered over us for about 10 seconds before joining the other 5 orbs. As they all floated away in the distance, they seemed to just disappeared. There was no wind. There was no noise. They were always at least 15-40 feet away from us until they finally floated off and disappeared in the distance.
Watch this UFO destroying a chemtrail over Paris, France
Watch this UFO destroying a chemtrail over Paris, France
This interesting daytime footage was recorded over Paris, France on 28th September 2016.
Witness report:
I caught an extraordinary UFO sighting. I was watching an odd looking light crossing the sky at variable speeds around my house, during the sunset. To me it was just some sort of helicopter, or maybe a drone. But after 5 or 10 minutes, I began suspecting the object not to be man-made. It was performing weird maneuvers, accelerating and decelerating randomly. When the light started to accelerate towards a huge Chemtrail, I took my camcorder and tried to find it in the distance. The object stopped in front of the Chemtrail, and slowly destroyed it. Indeed, the trail was being “consumed” progressively. I was simply speechless. I still can’t believe what I caught. The Chemtrail got literally perforated! I can’t be 100% sure it’s due to the object itself, but I’m sure there’s a link between it and the Chemtrail. Such a huge trail can’t just disappear like that, for no reason! And only a small portion of the trail gets erased, justly around the object! After the UFO attacked the trail, it moved backwards and flied West, in my opposite direction. It disappeared pretty quickly. Sorry for zooming out a little bit too early, my camcorder screen is really small, and doesn’t have that much pixels… The object got so far away at the end, I simply thought it was not there anymore. What was that object? Man-made prototype to delete Chemtrails? Some extra-terrestrial technology made to protect us? (maybe a bit far-fetched, but seriously, have you ever seen that before?) I just don’t have a clue of what this is.
UFO Sighting Revealed In Leaked U.S. Security Footage
UFO Sighting Revealed In Leaked U.S. Security Footage
Another footage has made the rounds online that may have confirmed a real UFO sighting. The video that has been leaked is said to belong to the Department of Homeland Security of the U.S.
The alleged leaked video shows a UFO ascending from the sea and splitting in half. The movements of the object are so strange to everybody. The mysterious object appears to be a metallic sphere. It moves quickly above and dives into the ocean, then seems to change shape or tumble.
The Scientific Coalition for Ufology (SCU) claimed that the video was from the DHS through a whistleblower. SCU website says the UFO has different features to any known object and its characteristics can’t be explained.
Since it made available online, several others came forward to claim they also saw the UFO.
SCU just released the video recently, but they noted that it was shot back in 2013. They explained that the released of the video had been delayed to confirm its authenticity first before publishing it for the public.
According to the report, the video was shot at an airport in Aguadilla, Puerto Rico on April 25, 2013, 9:20 p.m. The DHS crew of a DHC-8 Turboprop aircraft from Customs and Border Protection of the U.S. reportedly monitored the UFO activity.
According to the report, the crew of the DHC-8 plane noticed a strange, pinkish, red light over the ocean during its routine flight. Not informed of any incoming traffic, they radioed the presence of the UFO.
The tower crew responded that they also noticed the object but could not identify it.
SCU confirmed the flight was delayed due to the UFO sighting that night. Also revealed in the report is the video of the plane circling the airport two times before taking off.
The unknown object was allegedly flying from 40 mph to 120 mph at between 3 and 5 feet. The strangest part of the incident was that it went into the ocean about half a mile before darting back up and out of the ocean and appeared to split into two.
Chunk of Lightweight Metal Is Believed To Be An Old Proof That Alien Once Visited Earth
Chunk of Lightweight Metal Is Believed To Be An Old Proof That Alien Once Visited Earth
A mysterious piece of aluminum is being considered as 250,000-year-old evidence of alien existence on Earth. The old metal was discovered in communist Romania in 1973, but it wasn’t made public at the time.
After several examinations, the object is found to have made of 12 metals and 90 percent aluminum. Romanian officials concluded it is a 250,000 years old chunk of metal.
A laboratory in Lausanne, Switzerland later confirmed the initial results.
The large chunk is being hailed as an intriguing find because humanity wasn’t producing metallic aluminum until around 200 years ago.
In 1973, three objects measuring 33 feet or 10 meters was discovered under the ground on the shores of the Mures River. Archeologists identified two of the objects as fossils. The third one is a light metal and suspected to be the end of an ax.
All objects being discovered were sent to Cluj City in the region of Transylvania, Romania. Experts quickly determined the two as large bones of an extinct large mammal that died around 10,000 to 80,000 years ago. However, they were stunned to know that the third object was a piece of lightweight metal that seemed to have been manufactured.
The object in question is 7.8 inches or 20 centimeters long, 4.9 inches or 12.5 centimeters wide, and 2.8 inches or 7 centimeters thick.
Puzzled experts concluded that the piece of metal could be manufactured as part of a more complex mechanical system because it has concavities.
Now, the results have brought speculations of UFO and alien visitations in the past.
Deputy Director of the Romanian Ufologists Association, Gheorghe Cohal, believes that there’s a big chance that the third object is an old UFO fragment because it comprises with substances that could not be combined with technology on Earth.
Meanwhile, local historian Mihai Wittenberger believes the object is just a piece of a German aircraft during World War II, particularly from the landing gear of Messerschmitt ME 262.
However, this suggestion doesn’t explain the age of the lightweight metal.
The mysterious metal object is currently on display at the History Museum of Cluj-Napoca with a description saying “origin still unknown.”

UFO sighting filmed over Pomona, California 22-Oct-2016
Check out this UFO video that was filmed on 22nd October 2016 over Pomona, California.
Witness report:
I only got the end of it before it dissappeared – It was around 8pm were having a family party theres about 100 guest present and my cousin starts filming me and notices 2 lights and in spanish he says “Oh were dead look they are coming for us” By they he meant the lights and in the video he films the lights right before they dissappear. Once they dissappeared they never appeared again
In another alien and UFO related activity, a mysterious footage has come up on YouTube that shows a supposed fleet of flying saucers over Santiago's sky in Chile, South America.
Ever since the footage surfaced, people have begun to talk about the extraterrestrial activity as a fair number of viewers think that the sighting was nothing but UFOs.
The video which has been snapped over Santiago's sky appears to show four flying saucers, reports Daily Express. At first, the glowing lights seem to be floating in the distance, making a strange formation and then they spread out only to disappear completely in seconds. The pictures were taken on Thursday at 6 p.m. local time.
Later, they were sent by the photographer to the Mutual UFO Network aka MUFON- the biggest organization in the world dedicated to UFO research and study. According to the said photographer, he did not take the pictures with the intention of capturing UFOs and they were detected later after a review of the snapshots.
On the other hand, MUFON has said that it gets so many reports on a daily basis that it is unable to investigate every case. Nevertheless, it would not take much time for the body to figure out if they are UFOs or something else. As of now, some, including one forensic investigator of UFO pictures, said that they might also be reflections of light inside the building from where the photos were taken.
Meanwhile, the social media is divided in opinion about the video of the flying saucers, reports The Daily Mail. One viewer says that he initially thought that the flying objects were Chinese lanterns tied together but they were moving at a great speed. Another said that they seemed very real. Some said that the UFO claims were false as the lights were nothing but drones flying over the city.
It may be mentioned here that Chile has witnessed many UFO sightings and one of its cities, Andean town of San Clemente has become the hub of such activities and it is known as the country's capital for flying objects.

'Spiders' on Mars: Citizen Scientists Investigate Strange Martian Terrain
'Spiders' on Mars: Citizen Scientists Investigate Strange Martian Terrain
By Samantha Mathewson, Space.com Contributor

NASA's Mars Reconnaissance Orbiter (MRO) has been surveying strange "spider-like" surface features on Mars for years, and now citizen scientists are helping the orbiter hone in on areas that require further investigation.
These prominent surface features are found near Mars' south pole, and are believed to be linked to seasonal changes. The planet's polar ice caps thaw bottom-side first in the spring, causing carbon dioxide to build up and carve deep channels in the terrain, according to a statement from NASA.
"The trapped carbon dioxide gas that carves the spiders in the ground also breaks through the thawing ice sheet. It lofts dust and dirt that local winds then sculpt into hundreds of thousands of dark fans that are observed from orbit," Meg Schwamb, a planetary scientist from the Gemini Observatory in Hawaii, said in the statement. "For the past decade, [the orbiter's instrument] HiRISE has been monitoring this process on other parts of the south pole." [Latest Photos from NASA's Mars Reconnaissance Orbiter]]
Context Camera (CTX) aboard the MRO captured the images of these spider-like cracks and crevices, which volunteer citizen scientists have analyzed using the website "Planet Four: Terrains."
With the observations from this citizen science project, NASA has added 20 new regions to the agency's seasonal monitoring campaign on Mars. The orbiter's High Resolution Imaging Science Experiment (HiRISE) camera will explore these regions in greater detail.
"It's heartwarming to see so many citizens of planet Earth donate their time to help study Mars," Candice Hansen, HiRISE deputy principal investigator, said in the statement. "Thanks to the discovery power of so many people, we're using HiRISE to take images of places we might not have studied without this assistance."
The new places of interest on Mars include some unexpected spider terrain, areas where the surface is composed of material that was ejected from impact craters. Previously, those areas were not associated with carbon dioxide ice sheets, and therefore not thought to have spider-like crevices.
The spider cracks may have formed on the material ejected from craters using a different mechanism than the ice sheets, Hansen said. "Perhaps on surfaces that are more erodible, relative to other surfaces, slab ice would not need to be present as long, or [need to be] as thick, for spiders to form. We have new findings, and new questions to answer, thanks to all the help from volunteers," Hansen added.
Roving is currently the most common way that robots on Mars get from A to B, but it isn't necessarily the most practical. Here are 10 ways that robots can move around on Mars
Credit: NASA/JPL-Caltech
1. Mars Helicopter
This proposed robotic helicopter could triple the distances that Mars rovers could drive in a day and help pinpoint interesting targets for study, NASA researchers said. The low-flying scout helicopter would travel ahead of a rover to scope out the best driving routes. Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have been testing the design, but the agency has no concrete plans to take the helicopter to Mars — yet. Read more about the Mars Helicopter here.

2. Extreme Access
Engineers at NASA's Kennedy Space Center have invented an autonomous quadcopter, or drone, to fly on Mars. The machines are fast and flexible and can squeeze into places that other Mars robots cannot. They will be able to collect soil samples and return them to a mothership, which doubles as a charging station. Read more about the Mars drones here.

3. Entomopter
Insects inspired the design for this aircraft, called an Entomopter. Conventional types of helicopters and airplanes would have a hard time maneuvering through Mars' thin atmosphere, but the rapidly flapping wings on this aircraft design make flying on the Red Planet more practical. Other aircraft have to fly at over 250 mph (or 400 km/h) to remain airborne, which means that landing or taking off from the Martian surface are out of the question. But the Entomopter can fly slowly, land, take off and even crawl! It would be able to collect samples and return to a home base (like the rover pictured in the foreground) to recharge. A team led by Anthony Colozza at the Ohio Aerospace Institute in Cleveland received funding from NASA's Institute for Advanced Concepts in 2002 to develop this design for a Mars aircraft. Watch the Entomopter in action in this video.

4. LDSD, the 'Flying Saucer'
NASA's Low-Density Supersonic Decelerator project combines a balloon with a rocket to deliver huge payloads to the Martian surface — up to 15 tons. Mars Science Lab, the Curiosity rover, weighs only 1 ton and is currently the biggest spacecraft to land on Mars. LDSD could one day even deliver something as heavy as 100 tons or more, NASA officials said. The flying-saucer-shaped balloon will help slow down the landing in Mars' thin atmosphere. Read more about LDSD here.

5. Prandtl Glider
Student interns at NASA's Armstrong Flight Research Center in Edwards, California, helped to design this prototype of an engineless Mars glider called Prandtl-m. The design for this glider was inspired by boomerangs and birds and is based on a concept developed by German engineer Ludwig Prandtl around a century ago. This glider has no rudder and a slight twist in its wings, which helps to minimize air resistance and maximize efficiency. At Mars, it would be deployed high up in the atmosphere and collect data while floating down to the surface. NASA said it hopes to see one of its Prandtl gliders hitch a ride to Mars with the upcoming Mars 2020 rover mission. Read more about the Prandtl project here.

6. Mini-Sniffer
This proposed foldable Mars airplane concept is based on the design of a craft that flew on Earth in the 1970s. Three different versions of the Mini-Sniffer were developed by NASA to fly over Earth and test the upper atmosphere for pollution. Dale Reed, a researcher at NASA's Dryden Flight Research Center in Edwards, California, earned a patent in 1977 for the proposed Mars airplane. But NASA's plans for the Mars Mini-Sniffer never got off the ground.

7. ARES Mars Airplane
Rocket-powered airplanes could be the solution to the flying problems posed by Mars' thin atmosphere. This aircraft, called the Aerial Regional-scale Environmental Surveyor (ARES), could fly over mountains, craters and volcanoes on Mars — places that terrestrial robots often cannot reach. It was developed at NASA's Langley Research Center in Virginia. A prototype has already been built and tested, and now the ARES team said it hopes to send its aircraft to Mars via NASA's Mars Scout Program. Read more about ARES here.

8. Tumbleweed Rovers
One proposed way to travel on Mars is essentially a giant beach ball that rolls around in the wind. It wouldn't need any engines — just the wind. Engineers at NASA's Jet Propulsion Laboratory said that a payload of scientific instuments would be suspended inside the ball with tension cords. If scientists decide that one of these rovers needs to stop to take a measurement, the ball can be partially deflated to keep it from blowing away. NASA has already performed field tests with tumbleweed rover prototypes on Earth, but they have yet to be tested on Mars.

9. Roving with Wheels
So far the most popular type of robotic Mars explorer has been the rover. These types of Mars robots are somewhat comparable to vehicles that rove around on Earth, at roughly the size of a compact sedan. Several rovers have been sent to Mars, but only two are still functioning today: NASA's Curiosity (Mars Science Laboratory) and Opportunity. Another NASA rover, named Spirit — Opportunity's twin — went silent in 2010 after one of its wheels became trapped in the Martian sand.
Though the remote-controlled rovers may be the most intuitive form of robot for humans to build and operate, they do have some drawbacks. Aside from the risk of getting stuck like Spirit did, rovers can't drive very fast on Mars. Curiosity creeps along at about 2 inches (5 centimeters) per second, or 0.11 mph (0.18 km/h). Some areas of Mars are inaccessible to rovers, like steep mountains ridges or craters. [Infographic: Mars Explored: Landers and Rovers Since 1971]

10. Hopping Bots
Someday, Mars robots could get around on the Red Planet by hopping from place to place. These vehicles would use gas from the Martian atmosphere to propel their rockets and leap around. Researchers in England have proposed a hopping robot that uses radioactive isotopes as an initial power supply to squeeze gas into thrusters and heat it up before the propulsion system can begin powering the hopping. A hopper like this could fly in 0.6-mile (1 kilometer) hops at least, the researchers said. Read more about the hopping robots here.

The Red Spider Nebula welcomes Halloween with its eerie lobes and ghostly shine.
Large ripples constitute the expansive lobes of the Red Spider Nebula. The two lobes of the nebula represent a typical expression at the end of a star's life, with material from the star gushing into space at high speeds. [Haunting Photos: The Spookiest Nebulas in Space]
The nebula, thousands of light years from Earth in the constellation of Sagittarius, contains one of the hottest known stars which creates waves 100 billion kilometers (62.4 billion miles) high with its powerful cosmic winds. The speed of the waves arise from supersonic shocks forming from local gas compression, heating and rapid expansion in the lobes. Atoms trapped in the the shock create the dazzling radiation seen here.
The Hubble Space Telescope captured using the Wide Field and Planetary Camera 2 (WPFC2) in September pf 1997. The WPFC2 uses five different filters and light from the different elements are colored differently — sulfur ions in red, nitrogen ions in orange, ionized hydrogen in green, atomic oxygen in light blue and ionized oxygen in dark blue.
Hubble has been returning images of the deep recesses of our Universe to us since April of 1990. After being repaired and upgraded with five separate Space Shuttle missions, with the last in 2009. While Hubble could operate into the 2030s, its successor, the James Webb Space Telescope (JWST) is scheduled to launch in 2018.
UFO Rods Seen Moving Past Volcano Live Cam On Oct 24, 2016, Video, UFO Sighting News
Moving Past Volcano Live Cam On Oct 24, 2016, Video, UFO Sighting News
Date of sighting: October 24, 2016 Location of sighting: Popocatepetl, Mexico Here is a great example of rods. They were caught yesterday on a live volcano cam. There rods following each other side by side. Also in the distance a unknown craft moves closer to the volcano, but the video ends so we could not see if it emerges or not from the other side. Its rare to catch one, but to see three fly side by side. Wow, very exciting video. Scott C. Waring
Normaal gesproken gaat zo’n stofschijf hooguit zo’n 30 miljoen jaar mee, maar deze schijf is al 45 miljoen jaar oud!
We zien het vaak rond jonge sterren: een gas- en stofschijf. Materiaal in de schijf botst op elkaar en klontert samen en kan zo planeten vormen.
Oud Astronomen hebben nu – met behulp van het publiek – een rode dwerg ontdekt die ook zo’n stof- en gasschijf bezit. Maar wat deze rode dwerg zo bijzonder maakt, is dat deze zijn stofschijf zo lang heeft weten vast te houden. “Dit soort schijven verdwijnen meestal binnen 30 miljoen jaar,” vertelt onderzoeker Steven Silverberg. Maar er zijn sterke aanwijzingen dat deze ster – en dus ook de schijf eromheen – al veel ouder is: zo’n 45 miljoen jaar.
Leeftijd Het vaststellen van de leeftijd van een ster is doorgaans vrij lastig. Maar deze rode dwerg lijkt tot een groep sterren te behoren die allemaal ongeveer even oud zijn. En dat maakte het vaststellen van de leeftijd van de ster een stuk gemakkelijker. “Meer observaties zijn nodig om te bepalen of de ster werkelijk zo oud is als we denken,” vertelt onderzoeker Jonathan Gagné.
Planeten Grote vraag is natuurlijk of er in de stofschijf rond de oude ster ook daadwerkelijk planeten aan het ontstaan zijn. Het zou zeker kunnen. De meeste exoplaneten die tot op heden zijn aangetroffen zijn voortgekomen uit een schijf zoals we die nu rond deze rode dwerg zien. Daar komt nog eens bij dat deze ster qua type vergelijkbaar is met de ster die het dichts bij de aarde staat – Proxima Centauri – en waarvan onlangs werd aangetoond dat deze eveneens een planeet bezit.
De ontdekking van deze ster en stofschijf vloeit voort uit het Disk Detective-project. Dit project is gericht op de ontdekking van nieuwe stof- en gasschijven rond jonge sterren en put uit gegevens verzameld door onder meer de Wide-field Infrared Survey Explorer (WISE). Nu is het natuurlijk onbegonnen werk voor een handvol onderzoekers om al die gegevens door te spitten en dus deden ze een beroep op het publiek. Met succes, want sinds januari 2014 zijn al zo’n 30.000 mensen in de gegevens gedoken. “Zonder hun hulp zouden we dit object nooit gevonden hebben,” stelt onderzoeker Marc Kuchner. “De WISE-missie alleen al spotte 747 miljoen objecten, waarvan enkele duizenden naar verwachting een stofschijf bezitten.”
Sommigen weten het zeker: nieuwe beelden van Curiosity onthullen dat het leven op Mars helemaal klaar is met onze aanwezigheid daar.
Op internet is een opmerkelijk filmpje opgedoken dat diep inzoomt op één van de foto’s die Marsrover Curosity onlangs heeft gemaakt. De focus ligt daarbij op het wiel van Curosity. En daar is – na langdurig inzoomen – iets geks te zien. “Een klein wezentje in het wiel van Curiosity,” zo schrijft de maker van het filmpje op YouTube. En dat wezentje kijkt – SMILE! – toevallig recht in de camera van Curiosity.
Doofpot Een geweldige ontdekking, zou je denken. Waarom heeft NASA deze dan niet van de daken geschreeuwd? Simpel, zo weet de maker van het filmpje. NASA wil ook dit weer in de doofpot stoppen. “NASA heeft vele tactieken voor het in de doofpot stoppen van anomalieën op Mars, zo hebben ze deze foto bijvoorbeeld donkerder gemaakt dan hun foto’s doorgaans zijn en wanneer ze dat doen, weet ik gewoon dat ze iets proberen te verbergen.” In dit geval dus een drie centimeter hoge alien die probeert om het wiel van Curiosity te saboteren.
Brein Een beetje vergezocht? De maker van het filmpje kan er weinig aan doen. Zo werkt zijn brein nu eenmaal. Wij mensen zijn geneigd om zelfs in heel onduidelijke beelden iets van betekenis te zien. En dan natuurlijk het liefst ook iets wat aan onze eigen verwachtingen voldoet of deze overtreft. Dus: stel je gelooft heilig in buitenaards leven en bent ervan overtuigd dat NASA het woord ‘doofpotaffaire’ heeft uitgevonden, dan gaan de beelden van Mars als je er maar lang genoeg op inzoomt je gedachten uiteindelijk vanzelf bevestigen. Dankjewel, hersenen!
Geen drie centimeter hoge aliens op Mars dan? Naahh, waarschijnlijk niet. Maar zeg nooit nooit.
Nieuw onderzoek trekt versnelde uitdijing van universum in twijfel
Nieuw onderzoek trekt versnelde uitdijing van universum in twijfel
Caroline Kraaijvanger
Het bewijs voor de versnelde uitdijing – dat drie astronomen in 2011 de Nobelprijs opleverde – is bij nader inzien toch niet zo overtuigend.
Aan het eind van de jaren negentig kwamen drie astronomen tot de conclusie dat het universum versneld uitdijde. Ze baseerden zich op een analyse van supernova’s van type Ia en mochten jaren later – in 2011 – een Nobelprijs in ontvangst nemen voor hun ontdekking. De wetenschappelijke wereld heeft de uitdijing van het universum inmiddels omarmd en zelfs een mysterieuze substantie in het leven geroepen die de drijvende kracht zou zijn achter de versnelde uitdijing: donkere energie.
Dunnetjes Maar misschien moeten we nog eens goed nadenken over de versnelde uitdijing, zo suggereren onderzoekers van de universiteit van Oxford in het blad Scientific Reports. Het bewijs ervoor is – bij nader inzien – namelijk wat dunnetjes.
3 sigma De onderzoekers trekken die conclusie nadat ze 740 supernova’s van type Ia bestudeerden. Dat zijn er ongeveer tien keer meer dan de Nobelprijswinnende astronomen in de jaren negentig van de vorige eeuw analyseerden. “En we ontdekten dat het bewijs voor versnelde uitdijing hooguit een 3 sigma is, zoals natuurkundigen dat zeggen,” zo vertelt onderzoeker Subir Sarkar. “Dat is veel minder dan de “5 sigma-standaard” die nodig is om een ontdekking van fundamentele betekenis te claimen.”
Over sigma Sigma vertelt iets over hoe zeker wetenschappers van hun zaak zijn. Wanneer ze spreken over 5 sigma dan is de kans dat hun gegevens op toeval berusten één op 3 miljoen. Hebben ze het over 3 sigma dan is de kans dat hun gegevens op toeval berusten 1 op 1000. “Een vergelijkbaar voorbeeld is de recente suggestie dat er met behulp van de Large Hadron Collider een nieuw deeltje ontdekt was met een massa van 750 GeV,” legt Sarkar uit. “In eerste instantie had het een 3.9 en 3.4 sigma-meting in december. Maar nieuwe gegevens lieten in augustus zien dat de significantie gedaald was naar minder dan 1 sigma. Het was gewoon een statistische fluctuatie en het deeltje bestaat niet.”
Constante uitdijing En ook over de versnelde uitdijing van het universum zijn de onderzoekers dus nu iets minder zeker. Sterker nog: het nieuwe onderzoek wijst erop dat het universum heel constant uitdijt. Het zou goed kunnen verklaren waarom we maar geen grip kunnen krijgen op de aard van donkere energie – de hypothetische drijvende kracht achter de uitdijing – want als het universum niet uitdijt, is er ook geen donkere energie.
Kosmische achtergrondstraling Maar hoe zit het dan met al die andere gegevens die het idee van een sneller uitdijend universum onderschrijven? Je moet dan bijvoorbeeld denken aan de kosmische achtergrondstraling. “De kosmische achtergrondstraling wordt niet direct beïnvloed door donkere energie,” merkt Sarkar fijntjes op. Hij wijst er tevens op dat veel vervolgonderzoek uitgevoerd is met de gedachten dat het universum versneld uitdijt en dat donker energie daar achter zit, in het achterhoofd.
“Natuurlijk moet er nog veel meer werk verzet worden om de natuurkundige wereld hiervan te overtuigen, maar ons werk laat zien dat een belangrijke pijler van het standaardmodel van de kosmologie vrij wankel is. Hopelijk leidt het tot betere analyses van kosmologische data en inspireert het theoretici om genuanceerdere kosmologische modellen te bestuderen.”
Foto’s van ruimtesonde Cassini onthullen dat ook Saturnus met de wisseling van de seizoenen een nieuwe trendkleur kiest.
De blauwige, sombere gloed die in 2012 nog over de noordpool van de gasreus hing, heeft plaatsgemaakt voor een gouden gloed. Dat blijkt uit beelden van ruimtesonde Cassini.

Seizoenen Wetenschappers zoeken momenteel uit waarom de noordpool van kleur verandert, maar aangenomen wordt dat het alles te maken heeft met de wisseling van de seizoenen. Het zou met name samenhangen met fotochemische reacties – reacties waarbij de atmosfeer en zonlicht een rol spelen. Nu de noordpool het hoogtepunt van de zomer nadert, ontstaan er steeds meer fotochemische nevels in de atmosfeer boven de noordpool.
Nevels Als je goed kijkt, zie je dat op de noordpool een zeshoek pronkt. Dit is een straalstroom. Aangenomen wordt dat deze voorkomt dat deeltjes die buiten de zeshoek geproduceerd worden, de zeshoek binnendringen. Tijdens de zeven jaar durende winter op Saturnus namen de aerosolen die door fotochemische reacties ontstaan, af. Sinds augustus 2009 baadt de atmosfeer boven de noordpool continu in zonlicht en worden er ook in de zeshoek weer aerosolen geproduceerd, waardoor de noordpool van de gasreus vandaag de dag weer rijk is aan nevels.
Naast fotochemische reacties zijn er waarschijnlijk nog wel meer factoren die een rol spelen in de transformatie van de noordpool van Saturnus. Zo denken onderzoekers dat ook de winden in de poolgebieden onder invloed van zonnewarmte veranderen.
Astronomers have noted a change in the color scheme of Saturn's hexagonal storm from a bluish color to a more golden hue.
NASA experts assert this may be due to the increased production of photochemical hazes in the atmosphere as the north pole approaches summer solstice in May 2017.
A WHIRLWIND OF COLORS
The mysterious hexagon on Saturn’s north pole has just changed colors, as shown in recently released photos taken by NASA’s Cassini spacecraft. Discovered roughly 30 years ago, the geometric figure on Saturn’s northernmost area is actually a storm, which has been raging for decades, or even centuries.
The six-sided figure spans about 32,000 km (20,000 miles) in diameter, and extends for 100 km (60 miles) into the gas giant’s atmosphere. Each point in the hexagon rotates at its center at almost the same rate Saturn rotates on its axis. The perpetual hurricane in middle of the hexagon is constantly blasted by a jet stream of air at 321 km/h (200 mph).

Baffled scientists can only point to one probable explanation. According to NASA,
“The color change is thought to be an effect of Saturn’s seasons. In particular, the change from a bluish color to a more golden hue may be due to the increased production of photochemical hazes in the atmosphere as the north pole approaches summer solstice in May 2017.”
MYSTERIOUS LIKE MOST
Researchers believe the hexagon’s sides act like barriers, preventing haze particles from outside to enter. This likely explains why the hexagon turned blue sometime between November 1995 and August 2009, during a polar winter night. Presumably, while it was devoid of sunlight, Saturn’s north pole became clear of aerosols produced by photochemical reactions.
After Saturn’s equinox in August 2009, the planet’s polar atmospheres have been bathed in sunlight. Photochemical reactions in the atmosphere were triggered, producing aerosols that make the north pole’s hexagon hurricane hazy and appear golden in the recent Cassini photo.
It shouldn’t really come as a surprise that we don’t understand much of what’s going on in our giant gas neighbor. The mysteries of space continually baffle us, until technological advancescatch up and explain the previously unexplainable.
At that point, we’ll no longer be amazed. We’ll be mesmerized.

IN BRIEF
NASA donated a humanoid robot to MIT’s CSAIL to give students the opportunity to develop algorithms that could be used as part of NASA’s Space Robotics Challenge.
The challenge, which aims to create robots that could assist, or even potentially replace, human astronauts on extreme space missions, offers a $1,000,000 prize.

ONE SMALL STEP FOR A (SORT OF) MAN
By the time a human is finally ready to set foot on Mars, he or she could have a team of autonomous humanoid robots walking beside them.
Last November, NASA donated a humanoid robot, Robonaut 5 (R5), to MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL). They wanted to give students the opportunity to test the robot and develop algorithms for it that they could then use as part of NASA’s upcomingSpace Robotics Challenge. The challenge aims to create “dexterous autonomous robots” that could assist, or even potentially replace, human astronauts on “extreme space” missions.
“Precise and dexterous robotics, able to work with a communications delay, could be used in spaceflight and ground missions to Mars and elsewhere for hazardous and complicated tasks, which will be crucial to support our astronauts,” said Monsi Roman, program manager of NASA’s Centennial Challenges, in a press release. “NASA and our partners are confident the public will rise to this challenge and are excited to see what innovative technologies will be produced.”
ROBOTS. IN. SPACE.
Artificially intelligent robots capable of assisting human astronauts could become invaluable as we continue to push the boundaries of space exploration. Unlike current robots that must be controlled by human operators, autonomous humanoid robots would be able to work independently. They could be sent on missions prior to human astronauts deploying, remain behind to look after equipment, and generally free up crew members to do more complex and less dangerous work.
While expanding humankind’s knowledge of space is a reward in and of itself, the million dollar prize for the team that wins NASA’s Space Robotics Challenge is great additional motivation for MIT’s team to make sure its bot comes out on top.

Writing on his “Answers in Genesis” blog, Ham attempted to respond to Scottish astronomer Duncan Forgan, who has been running computer simulations about the possibility of alien civilizations.
“Jesus did not become the ‘GodKlingon’ or the ‘GodMartian’!” he wrote at the time. “Only descendants of Adam can be saved. God’s Son remains the ‘Godman’ as our Savior.”
