Military Denies Knowledge of Mystery Aircraft Seen Circling Canadian City for Days
Military Denies Knowledge of Mystery Aircraft Seen Circling Canadian City for Days
An unidentified aircraft seen circling overhead for days has residents of the Canadian city of Kingston wondering if something strange could be afoot. Kingston sits along Lake Ontario at the mouth of the St. Lawrence river a few hours from the major metropolises of Ottawa, Montreal, and Toronto. For days now, residents have seen an aircraft with “minimal lighting” flying over the city under the cover of darkness. Even more curious, not one law enforcement agency or branch of the military has stepped forward to claim responsibility for the craft. What’s going on in the skies over Kingston?
It’s probably just another one of those shadow government planes again turning the frogs gay with chemtrail magic.
The Kingston Whig Standardreports that the news paper has received multiple emails and calls about the unidentified aircraft. According to Kingston resident Doug Stewart, the aircraft appears to circle for hours in the dead of night:
It’s a mystery. I can hear it at 2 and 3 a.m., and I’ve only heard it after dark at about 6, 7, 8 p.m. Some nights it’s constant … it seems like it’s circling.
Other witnesses have estimated that the aircraft is flying fairly low around 3,000 to 5,000 feet and appears to circle the same area every five minutes or so. Naturally, many Kingston residents assumed that the nearby Canadian Forces Base Trenton, Canada’s busiest Air Force base, was to blame. However, Public Affairs Officer Capt. Graeme Scott reports that the aircraft isn’t theirs.
Many law enforcement agencies now operate spy aircraft equipped with incredibly high-resolution video cameras.
Likewise, the Royal Canadian Mounted Police have issued a rather opaque, somewhat passive aggressive statement denying any knowledge of the aircraft:
The RCMP’s primary concern is the safety and security of Canadians. We have multiple aircraft that support our mandate in Ontario and elsewhere in the country. To maintain the integrity of our investigations and operations, the location of our aircraft is not disclosed. We therefore have no additional information to share with you at this time.
With such little information to go on, Kingston residents are left in the dark about the plane circling their homes and who it might belong to. While many see this as an invasion of privacy, deciding who owns the airspace above privately-owned homes has proven tricky for federal governments. Should undisclosed, unidentified aircraft be able to loiter in the sky despite the public’s concern or alarm?
An asteroid belt is full of asteroids, so a collision in this narrow and crowded orbiting highway of rock wouldn’t seem to generate anything more than a “Duh!” from astronomers. However, a recent crash in the main asteroid belt between Mars and Jupiter caught their attention because of its violent impact which seems to have turned one of the asteroids into a comet with an extremely long tail. Doh?
“On 9 Jan. 2019, the Central Bureau for Astronomical Telegrams issued an electronic telegram reporting that the inner main belt asteroid (6478) Gault had a tail. This made the object a very important target to monitor and we managed to get a few images on two nights.”
That electronic telegram (nice to see someone is still using telegrams) was read by The Virtual Telescope Project – an advanced service provided by the Bellatrix Astronomical Observatory in Italy providing remote Internet access to several robotic telescopes for the general public – and distributed worldwide. 6478 Gault is already somewhat famous, having been discovered in 1988 by the astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California. The Shoemakers are best known for discovering the Comet Shoemaker–Levy 9, whose collision with Jupiter in July 1994 was televised worldwide.
Asteroid Gault (named for American planetary geologist Donald Gault, a pioneer in the field of impact cratering processes – coincidence?) is part of the Phocaea family of space rocks created 2.2 billion years ago by another collision which resulted in Gault (a large asteroid 3.7 km/ 2.3 miles in diameter, countless other little space rocks and 25 Phocaea, a huge asteroid about 75 km/46 miles in diameter. Researchers with the ATLAS project (Asteroid Terrestrial-impact Last Alert System) spotted the sudden appearance of a tail on Gault in late December/early January observations.
Active asteroid 6478 Gault last night from the @INGLaPalma after discovery by @TheGenghisKen@fallingstarIfA . The ejected dust extends > 400,000 km, more than the Earth-Moon distance.
British astronomer Alan Fitzsimmonstweeted that the tail is over 400,000 km/240,000 miles long and would stretch from Earth to the Moon and then some. Astronomer Gianluca Masi posted on the Virtual Telescope Project blog that the tail was most likely created by a collision that blasted a part of Gault into the smithereens that now make up the tail. (See the pictures here.) No one seems to know which rock – if it still exists – collided with 6478) Gault somewhere in November 2018. What the astronomers do know is that an asteroid with a tail is an extremely rare condition that they still don’t seem to fully understand – as evidenced by all of the conflicting stories about whether tail-streaming ’Oumuamua is a comet, an asteroid, a space ship or something else.
Comet or asteroid?
What is 6478 Gault now? If it keeps the tail, and astronomers will be monitoring it closely, then it’s definitely turned into some form of comet. If it loses the tail, it’s still an asteroid. If the collision knocked it hard enough to put it on a collision path with a planet (hopefully not Earth), it will make the Shoemakers famous once again.
Back in the 1970s,Paul Bennewitz– who died in 2003, in Albuquerque, New Mexico – had his own company that stood adjacent to Kirtland Air Force Base, also in Albuquerque. Its name was Thunder Scientific. All was good, as Bennewitz had a number of solid contracts with the military. And living and working so close to the base made things comfortable and handy for Bennewitz. It was the perfect relationship. Until, that is, it wasn’t. In shockingly quick time, Bennewitz’s life began to fragment in chaotic fashion. But, how and why did such a thing happen?
It’s important to note that by the late 1970s Bennewitz had been interested in UFOs not just for years but for decades. He had a large library of books on the subject and subscribed to a number of newsletters and magazines on the subject. On occasion, Bennewitz had seen – late at night and in the early hours of the morning – strange, unidentified objects flying over Kirtland Air Force Base and the nearby, huge Manzano Mountains. They could have been early drone-like craft being tested secretly. But, for Bennewitz they were alien craft.
Bennewitz’s head spun: he came to believe that aliens were in league with the U.S. Air Force, and that much of the secret program was run out of Kirtland. And he shared his views with staff at Kirtland, the CIA, the NSA, the Defense Intelligence Agency, the Pentagon, his Senator, his Congressman, and just about anyone and everyone in a position of power and influence. It was all but inevitable that by firing off lengthy letters about a secret alien-human operation at Kirtland someone would take notice. That’s exactly what they did.
While one school of thought suggests that Bennewitz was indeed tracking the movements of UFOs in the skies over Kirtland, another suggests that Bennewitz had actually stumbled on test-flights of new and radical aircraft, of the aforementioned drone kind. In the latter scenario, the government (as a collective term for all of those agencies and individuals that Bennewitz approached) decided to first politely, but quietly, request that Bennewitz bring his research to a halt. This was like a red rag to a bull. Bennewitz would hear none of it. He was primed and ready to go after the U.S. Government and to confirm what he saw as the dark and sinister truth of Uncle Sam’s liaisons with aliens. One man against the government? It was clear who was going to win; although Bennewitz couldn’t envisage such a thing at all.
Manzano Mountains
In ingenious fashion – but from the perspective of Bennewitz, in terrible fashion – a plot was initiated to, in essence, give Bennewitz exactly what he wanted to hear. So, well-placed government agents, intelligence operatives, and experts in the fields of counterintelligence and disinformation, all fed Bennewitz fictitious tales of dangerous ETs, of thousands of people abducted and mind-controlled in slave-like fashion by the aliens, of terrible experiments undertaken on people held below a huge “underground base” in the town of Dulce, New Mexico, and of a looming confrontation between the human race and the deadly creatures from another galaxy.
That the data was all coming to him from verifiable insider sources impressed Bennewitz and led him to believe their every word – which is precisely what the government was gambling on. The government then tightened the noose even tighter around Bennewitz’s neck: they fed him more and more horror-stories of the alien variety. And, slowly and bit by bit, Bennewitz’s paranoia grew. He couldn’t sleep, he became stressed to the point where he required medication, and eventually had a nervous collapse and was hospitalized. The result: he walked away from UFOs, secret projects, and cosmic conspiracies as a crushed man. Which may well have been the intent of the government, anyway.
How do you wipe out an entire species of 60 ft long giant sharks? Blow up a star, of course. According to arecent paper, supernovas may have been the cause of a number of unexplained mass extinctions throughout earth’s history, including the monstrous and fantastically named giant shark species Megalodon, a relative of the great white shark, whose mysterious extinction some 2.6 million years ago has long puzzled scientists.
There are enough out there to confidently say that stars are exploding all the time. Luckily for us, space is big and our lives are relatively short, so the chance of us getting blasted by a supernova are pretty small. Still, sometimes it happens (roughly every 100 million years) and the earth gets whacked by a cloud of radiation that once made up some other poor solar system’s sun. Scientists have been looking for evidence of how cosmic events like supernovas impact earth and the recent study attempts to discover the role that they play in the rise and fall of species here on earth and the impact that they might have had on evolution. If you guessed that an exploding star would be really good at killing things, you’re right!
Fossilized Megalodon tooth.
According to Adrian Melott, astrophysicist at the University of Kansas and the author of the new paper, the mass extinction of megafauna like the Megalodon lines up with evidence of a supernova impacting earth. Isotopes of iron-60, which is extremely rare on earth yet common in supernovas, were found on the sea floor and the surface of the moon. Dating these isotopes reveals that, if they were dropped here by a supernova, that supernova rolled through our solar system 2.6 million years ago—right about when the Megalodon checked out. According to Melott:
“A lot of things would not leave a definite residue. [Iron-60] is smoking-gun evidence of something happening.”
The blast from a supernova could end species in a few ways. Other theories on how supernovas could impact mass extinctions point to indirect causes. The blast from a supernova could strip the earth’s ozone layer, for example, leaving species vulnerable to solar radiation and destroying ocean food sources like plankton and coral reefs. Cosmic rays could also seed clouds and create a “cosmic-ray winter,” according to Henrik Svensmark of the Technical University of Denmark, which would also result in the destruction of food sources.
Melott thinks that the supernova may have been a much more direct cause of the extinction, however. Supernovas release highly charged radioactive particles called muons. Getting hit by a cloud of muons probably wouldn’t feel like much at first, but the radiation exposure would soon cause irreparable genetic damage and mutations that, depending on the species, could be catastrophic. The bigger the animal, the worse the impact would be. For an animal the size of a human, the muon storm would increase cancer rates by 50 percent. Considering that the Megalodon was about the size of a school bus, it would get hit pretty hard.
Artist’s depiction of a supernova.
As evidence for his theory, Melott points to the sudden extinction of 36 percent of ocean species 2.6 million years ago at the end of the Pliocene era and the beginning of the Pleistocene. The extinct species were largely coastal dwelling, where the impact from muon radiation would be the most devastating. Unfortunately, highly radioactive particles like muons don’t leave any record of their presence, so it’s hard to tell just how catastrophic an impact it was. Yet there does seem to be a correlation between a supernova and a mass extinction, so it is likely that there was some sort of connection.
So, if you have a fear of shark infested waters, just remember: there’s always something bigger and badder on its way (but probably not for another 97 million years).
A radar mystery that began in the skies over parts of the United States late last year has some experts questioning whether the government is involved in secret tests, while others think odd weather might be to blame.
In early December, the National Weather Service reported on what they termed an “anomaly” over parts of the midwestern United States. Here at MU Brett Tingley reported on the incident, which was observed on radar over parts of Illinois, Kentucky, and Indiana. “Whatever was on radar appeared to be as dense as a thunderstorm,” Brett wrote, “but with the night clear and temperatures low, that theory was ruled improbable.” It was determined that the likely cause of the radar traces had been chaff, a substance composed mostly of aluminum that is released from aircraft during military operations and exercises to “confuse enemy radar.” However, as Brett noted at the time, meteorologist Greg Meffert with the NWS stated that he had “never seen [chaff] quite this hot.”
A few days later, Joseph Trevithick over at The Warzone wrote about a second radar incident, reporting that similar anomalous traces had appeared over parts of Maine and Florida just two days later. The National Weather Service confirmed on their Twitter account that the new radar anomalies also resembled chaff, although Trevithick noted that the December radar blips seemed to last longer than chaff typically does.

(Wikimedia Commons).
“We have already reached out to the National Guard Bureau,” Trevithick wrote, “but at the time of writing, we have not received any additional information about this new incident over Maine. We’re reaching out to additional commands regarding the plume in Florida, as well.”
Since that time, little else was reported about the incidents. That is, until today, when Jon Webb with the Evansville Courier & Press wrote about the peculiar December incidents. While they do appear to be related to military operations involving chaff, a few questions do remain.
“Whatever it is, it’s exceedingly strange,” Webb wrote, citing an email exchange he had with a member of the Mutual UFO Network (MUFON) who told him, “We believe there is more to the story than what the FAA and military and publications such as ‘The War Zone’ are telling us.” (Does it matter to the unnamed MUFON investigator that even The Warzone’sTrevithick noted having some problems of his own with the chaff theory? Maybe they didn’t read to the end of the article… who knows.)
“More NWS hubs will get confused,” Webb concluded, “And more conspiracies will be born.”
So what was going on back in December, and does the assertion by Trevithick and others that certain aspects of the incidents didn’t resemble “typical” military exercises involving chaff amount to anything?
A pair of B-1B Lancers, 28th Bomb Squadron, deploy chaff and flares during a military exercise
(public domain).
According to a Department of National Defense study from 2008, chaff is described as “a radiofrequency countermeasure released by military aircraft (ships and ground vehicles) to confuse enemy radar.” At the time this report was produced, chaff was used in approximately 26 U.S. states.
The report states that “the effective use of chaff can be maintained only by practicing in-flight deployments during training issues.” It goes on to say that, “The release of chaff into the environment during these exercises has raised concerns among both public-interest groups and the government regarding the fate and environmental impact of chaff particles.”
Concerns about the environmental effects of chaff go back to at least 1993, resulting in a military report that indicated that there were few–if any–significant environmental risks associated with its use in military exercises. However, a 1998 report by the congressional General Accounting Office continued to argue that chaff could have negative environmental effects, in addition to potentially interfering with civilian ATC radar systems.
More recently, controversies arose over the use of chaff last year in relation to the companies that produce it, and their potential future ownership by foreign entities. Presently, Esterline Defense Technologies (also known by the name Armtec) is the only company in the United States that produces chaff for use in military activities. In 2018, it was reported that Esterline/Armtec would be acquired by the UK-based TransDigm Group Inc. The news prompted a bipartisan letter from Congress to Jim Mattis, then-U.S. Defense Secretary, calling for the U.S. government to block the deal.
“TransDigm has repeatedly purchased companies that are the sole providers of Department of Defense items and engaged in price gouging,” the letter, co-authored by California Democratic representative Jackie Speier and North Carolina Republican Walter Jones, argued. “The abuses have been sufficiently common and severe enough to warrant a DoD inspector general investigation. Unsurprisingly, Esterline is the sole DoD chaff provider and one of two flare providers. The alarm bells should be ringing.”
In essence, the controversies surrounding chaff and its use seem to have been an ongoing point of contention for decades. But in sum, do military exercises account for the odd radar returns that were occurring late last year? Also, could it be possible that the military is testing a new kind of chaff or similar substance, following the news that Esterline/Armtec could be acquired by TransDigm? There is no proof that this is the case, but if we were to speculate, it might account for some of the more unusual aspects reported with the December incidents, as well as why so many were reported around that time.
Then again, for all we know maybe the December radar incidents were just good old, Esterline/Armtec chaff that was clouding up radar systems over the Midwest and parts of the East Coast. At present, no further information about the incidents has been made available to the public, nor have any similar radar anomalies been reported… so the rest is left (as per usual) to our imaginations.
Brian Hanley who has published the UFO footage on January 9, 2019, states: I usually cover politics, but when Sam Chortek and Jimmy Chappie came to me with this exclusive UAP footage, I had to break the story.
At first there was a lot of doubt whether the recording was real or faked on which Brian Hanley decided to release the raw footage which was recorded by a DJI Inspire Drone over Beaver, Utah, just a couple of hours (by car) from Area51.
The first original footage shows the object that moves at an incredible speed. The second footage shows the object in slow motion making it easily recognizable.
I do not exclude that the object is of extraterrestrial origin but since this UFO fastwalker has been filmed near Area51 it is quite possible that the object, which is very similar to other fastwalkers that fly through our atmosphere, belongs to one of their secret projects.
New England has been dumped with snow due to winter storms that also brought bone-chilling cold this week. However, the occurrences have been shrouded with a strange ice formation to one Maine river.
In Westbrook City in Maine, around 20-minute drive east of Portland, a mysterious disk of ice has appeared in the Presumpscot River.
City officials estimated the disk to be around 300 feet wide and about the size of a football field.
UFO enthusiasts who saw the disk formation believe the disk is an alien spaceship disguising itself as a natural phenomenon caused by winter storms. They said that the disk was spinning on a frozen river signifying that it was conducting an activity under the river.
City officials went the extra mile with the use of a camera drone to capture stunning images of the disk from above.
According to the official explanations, the varying currents of the river formed the disk. Part of the river flows in a rapid straight line movement, but currents near the other bank flow slowly in a semi-circle. That portion of the river freezes because of the slower currents. The formation of the ice disk is due to the clockwise motion.
However, UFO enthusiasts argue that the formation is a perfect disk and aliens operating under the river have something to do with it. They said that it could be extraterrestrials carrying out a mission under the river.

Last week, astronomers working with the ATLAS project in Hawaii announced an astonishing change to asteroid 6478 Gault. The space rock had sprouted a tail. It is now gliding through the asteroid belt giving every appearance of being a comet. On Jan. 9th, Damian Peach of Selsey UK photographed the 6478 Gault and its 400,000 kilometer-long tail:
And continues:
Gault's tail may be a result of a recent collision. Researchers with the ATLAS project have looked at images of Gault in Dec. 2018 and Jan. 2019. Extrapolating its appearance backwards in time, they suggest that Gault hit another object in the asteroid belt in Nov. 2018.
Active asteroid 6478 Gault last night from the @INGLaPalma after discovery by @TheGenghisKen@fallingstarIfA . The ejected dust extends > 400,000 km, more than the Earth-Moon distance.

Earth’s North Magnetic Pole's 'Erratic Motion' Forces Geologists To Unprecedented Move
Earth’s North Magnetic Pole's 'Erratic Motion' Forces Geologists To Unprecedented Move
Something is happening with Earth’s magnetic field and scientists can’t figure it out.
At the very top of theworldsits Earth’s north magnetic pole. Recently, however, something very strange is happening to it. Driven by liquid iron sloshing around within the Earth’s core, the north magnetic pole has been edging away from Canada and towards Siberia. The world's geomagnetism experts have been forced into doing something very rare due to the fact that the magnetic pole is moving so quickly.
What are the scientists doing?
Due to the magnetic poles erratic movements, on January 15th the experts are set to update the World Magnetic Model. This is quite a big deal because this a model which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones. The model wasn't meant to be changed until at least 2020 as the latest version only came out in 2015, however due to the movement being so severe, the model has to be changed now as the error is only getting larger and larger.
What causes this?
There isn't just a single cause, there are several. The problem lies partly with the moving pole and partly with other shifts that occur deep within the planet. The liquid churning in Earth’s core, which was mentioned earlier, generates most of the magnetic field, which varies over time as the deep flows change. For example, in 2016 part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean. This is just another example of how quickly the magnetic pole can change. The historical changes can be seen in the diagram below.
In 2018, the pole crossed the International Date Line into the Eastern Hemisphere and is currently moving in a direction headed towards Siberia.
The geometry of Earth’s magnetic field magnifies the model’s errors in places where the field is changing quickly, such as the North Pole. The fact that the pole is traveling so fast makes this region more prone to large errors.
What’s next?
The magnetic pole will continue to move in the future and in any direction is possible. No one knows where it will go next as it's completely random. Therefore the magnetic pole will definitely be keeping geomagnetic experts busy over the next few years and there will be no shortage of work for them.
It is definitely an interesting development and I for one will be keeping an eye on new publications to see where it goes next and what will happen in the future!
A three-year-old startup is trying to launch rockets into space that are almost entirely 3D printed. And it just got permission from the U.S. Air Force to launch from thehistoric Launch Complex 16at Cape Canaveral in Florida.
Relativity Space — a rocket-building company founded by SpaceX and Blue Origin alumni — revealed a new contract with the U.S. Air Force this week that would allow it to launch from a site that has been unused since 1988, according to Quartz. If the company manages to regularly launch rockets from the site, it could be able to extend the contract into a 20-year exclusive agreement with the Air Force.
Giant Rocket Printers
Relativity Space has ambitious plans: it wants to 3D print an entire rocket with its groundbreaking, building-sized Stargate metal 3D printer, then launch it into orbit. Its long term plans are also enormous — the company wants to eventually 3D print rockets on Mars, according to its official website.
3D printing a rocket would be simpler and allow for more efficient designs, fewer moving parts, and faster construction. The company’s first planned launch vehicle called Terran 1 would only take 60 days to print, and would have a max payload of 1,250 kg (2756 lbs) to low-Earth orbit — at least if everything works out as planned.
Growth Spurt
Relativity Space is going through a growth spurt right now. Its number of employees rose from 14 to 60, co-founder Tim Ellis toldArs Technica. It’s also planning a test launch of the Terran 1 rocket in 2020, with commercial missions starting in 2021.
Using 3D printing technology to blast off into space is an exciting idea, and could make building rockets faster and cheaper. But the proof is in the pudding — or rocket fuel.
Here's something you don't see every day — the glint of freshly fallen rain on the surface of an alien world.
NASA's Cassini spacecraft spotted a big reflective feature near the north pole of Saturn's huge moon Titanin June 2016, a new study reports.
Cassini discovered numerous lakes and seas of liquid hydrocarbons on Titan's frigid surface during the probe's pioneering 13 years in the Saturn system. But this newfound bright patch — which covered 43,330 square miles (120,000 square kilometers), about half the combined surface area of the Great Lakes here on Earth — isn't one of them.

The feature disappeared relatively quickly, study team members said, suggesting that it was a big puddle of methane rain that evaporated away.
"It's like looking at a sunlit wet sidewalk," lead author Rajani Dhingra, a doctoral student in physics at the University of Idaho in Moscow, said in a statement.
The likely rainfall event signals that summer weather had arrived in Titan's northern hemisphere by mid-2016, the researchers said. That's a little later than climate models had predicted.
"Summer is happening," Dhingra said. "It was delayed, but it's happening. We will have to figure out what caused the delay, though."
Saturn and its many moons take 29.5 Earth years to complete one lap around the sun, so seasons in the ringed-planet system each last nearly 7.5 years. Cassini arrived at Saturn in mid-2004, during the southern summer, and saw clouds and rainfall in Titan's southern hemisphere.
Titan is the only world beyond Earth known to have stable bodies of liquid on its surface. But this moon's weather system is very different than that of Earth's: The rain, rivers and seas of Titan are all composed of liquid hydrocarbons.
Cassini studied Saturn, its rings and many moons until September 2017, when the low-on-fuel spacecraft plunged intentionally into the planet's thick atmosphere. Mission team members ordered the death dive to ensure that Cassini never contaminated Titan and fellow moon Enceladus with microbes from Earth. Scientists think both of these satellites may be capable of supporting life as we know it.
Cassini captured the rainfall-glint image with its Visual and Infrared Mapping Spectrometer instrument, which was able to peer through Titan's thick, obscuring atmospheric haze.
The Cassini orbiter traveled with a European lander called Huygens, which touched down on Titan in January 2005, pulling off the first-ever soft landing on a moon in the outer system.
New Horizons zoomed within just 2,200 miles (3,500 kilometers) of Ultima Thule in the wee hours of Jan. 1, pulling off themost-distant planetary flyby in spaceflight history. Ultima Thule lies more than 4 billion miles (6.4 billion kilometers) from Earth — 1 billion miles (1.6 billion km) beyond the orbit of Pluto, which New Horizons encountered in July 2015.
The video, which mission team members released Tuesday (Jan. 15), captures 7 hours during New Horizons' final approach, just before the probe buzzed the snowman-shaped Ultima Thule. During those 7 hours, New Horizons closed the gap between itself and its target from 310,000 miles (500,000 km) to 17,100 miles (28,000 km), mission team members said. [New Horizons at Ultima Thule: Full Coverage]
And Ultima Thule gets sharper as it looms larger in the frame.
"The original image scale is 1.5 miles (2.5 km) per pixel in the first frame, and 0.08 miles (0.14 km) per pixel in the last frame," New Horizons team members wrote in a description of the new video.
"The rotation period of Ultima Thule is about 16 hours, so the movie covers a little under half a rotation," they added. "Among other things, the New Horizons science team will use these images to help determine the three-dimensional shape of Ultima Thule, in order to better understand its nature and origin."
The brief video also shows why New Horizons didn't detect any brightness variations from Ultima Thule during the approach phase, a surprising development that initially puzzled the mission team. The lack of such a "light curve" is expected for spherical objects, which don't shift from a viewer's perspective as they rotate, but early data indicated that the 21-mile-long (34 km) Ultima Thule was highly elongated.
As we can now see, it was all about New Horizons' orientation to Ultima Thule. The object's pole of rotation was pointing directly at the approaching spacecraft, so New Horizons didn't see any appreciable changes in the light bouncing off Ultima Thule.
We should expect more cool imagery and data from the flyby in the coming weeks. But be patient: Because of low data-relay rates, it'll take about 20 months for all the flyby information to come down to Earth, mission team members have said.
And Ultima Thule may not be New Horizons' last flyby target. The probe is in good enough health, and has enough fuel left, to potentially perform yet another deep-space encounter, if NASA approves another mission extension. (The probe's original mission centered on the Pluto flyby, and the Ultima Thule encounter was the focus of a mission extension that runs through 2021.)

Scientists think that they've spotted a rare, Jupiter-sizeblack holecasually strolling through theMilky Way galaxy.
Of course, scientists can't see any black holes directly — but new research tracking a celestial cloud structure saw strange behavior that may have been caused by just such an invisible object. That data came courtesy of theAtacama Large Millimeter/submillimeter Array(ALMA), a set of 66 telescopes scattered across the Atacama Desert in northern Chile.
"When I checked the ALMA data for the first time, I was really excited because the observed gas showed obvious orbital motions, which strongly suggest an invisible massive object lurking," lead author Shunya Takekawa, a physicist at the National Astronomical Observatory of Japan, told New Scientist.
Takekawa and his colleagues were using ALMA to study two gas clouds, which the team nicknamed Balloon and Stream for their shapes, during a two-day period in May 2018. During that time, they watched the gas moving strangely, seeming to spin around a center.
That movement allowed the team to calculate that 30,000 times the mass of our sun was packed into an object the size of Jupiter at the center of the movement. Those characteristics, combined with the lack of light coming from the location, suggest that the culprit is medium size for a black hole.
Scientists think tiny black holes and supermassive black holes are pretty common, but that there aren't a whole lot of medium-size black holes. Astronomers believe they've spotted two other black holes in this size range near the heart of the Milky Way. All three, if future observations continue to see evidence for them, may be escapees from the giant black hole at our galaxy's center.
The research is described in an article posted to the preprint server arXiv.org on Dec. 27.
New research led by members from the University of Southampton has identified a black hole spinning around its axis near its maximum possible speed.

The study involved an international team of astronomers. Starting from observations taken with state-of-the-art sensors, the researchers found evidence that 4U 1630-472, a stellar-mass black hole in our galaxy, is rotating really, really fast — around 92% to 95% of a black hole’s theoretical maximum rotational speed.
Material keeps falling into this black hole as its spinning, being subjected do immense gravitational stress and temperatures. The environment is so violent that this matter shines brightly in X-rays, the team reports, which they used to establish that 4U 1630-472 is rotating and calculate its speed.
So fast it’s glowing
If a black hole is rotating rapidly enough, it should — according to the general theory of relativity — distort space-time around it differently than a non-rotating black hole, the team explains. Such distortions would leave a measurable trace on the radiation emitted by the matter it’s absorbing.
Therefore, researchers can look at a black hole’s emission spectra to determine the rate it’s spinning at.
“Detecting signatures that allow us to measure spin is extremely difficult,” says lead author Dr. Mayukh Pahari from the University of Southampton. “The signature is embedded in the spectral information which is very specific to the rate at which matter falls into the black hole.”
“The spectra, however, are often very complex mostly due to the radiation from the environment around the black hole.”
Dr. Pahari says the team was “lucky” to obtain a spectral reading directly from the matter falling into the black hole, sans the background noise. Armed with that data, it was “simple enough to measure the distortion caused by the rotating black hole,” he says.
The findings from this study are significant, as this is one of only a handful of times we’ve managed to accurately measure a black hole’s spin rate. Only five other black holes have shown high spin rates, the team adds. Astronomical black holes can be fully characterized by mass and spin rate. Therefore, measuring these two properties is key to understanding some extreme aspects of the universe and the fundamental physics related to them.
Scientists measure the spin rates of supermassive black holes by spreading the X-ray light into different colors.

Titan has seas, lakes, and rivers — and now, researchers have found, it also has rainfall and seasonal variation.

If you’d picture a place that has an atmosphere and liquids on its surface, it probably wouldn’t be Titan. This frigid moon is only 50% larger than Earth’s moon and mostly consists of ice and rocky material. It features a young and smooth geological surface, with few volcanic or impact craters, and remarkably, it has not only an atmosphere, but also geological features dunes, rivers, lakes, seas, and even deltas. But there’s a key difference.
Unlike Earth’s seas, which consist of water, Titan’s seas consist of hydrocarbons such as methane and ethane.
Conversely, Titan features a nitrogen atmosphere and has a nitrogen cycle analogous to Earth’s carbon cycle, something which stunned astronomers when it was first discovered. The Cassini mission, which landed a probe on Titan in 2005, first revealed a surface which seemed to be shaped by fluids.
But Titan has far from shared all its secrets. Recently, astronomers have analyzed images suggesting that intense rainfall occurs on Titan, indicating the start of “summer” in the northern hemisphere. It’s something researchers were expecting for a long time, especiallyas rain had been previously observed in the southern hemisphere.
“The whole Titan community has been looking forward to seeing clouds and rains on Titan’s north pole, indicating the start of the northern summer, but despite what the climate models had predicted, we weren’t even seeing any clouds,” said Rajani Dhingra, a doctoral student in physics at the University of Idaho in Moscow, and lead author of the new. “People called it the curious case of missing clouds.”
New research provides evidence of rainfall on the north pole of Titan, the largest of Saturn’s moons, shown here. The rainfall would be the first indication of the start of a summer season in the moon’s northern hemisphere, according to the researchers.

The image was taken in 2016, by the near-infrared instrument on the Cassini probe, which offered the bulk of what we know about Titan. The instrument spotted a reflective feature covering approximately 46,332 square miles, which did not seem to appear on any other images of Cassini. The analyses suggest that this reflective feature represents a wet surface.
“It’s like looking at a sunlit wet sidewalk,” Dhingra said.
So we have a strong confirmation that seasons are happening on Titan, which confirms the predictions astronomers made. However, this poses a new question that researchers will have to answer.
“We want our model predictions to match our observations.” Dhingra said. “Summer is happening. It was delayed, but it’s happening. We will have to figure out what caused the delay, though.”
The study was published in Geophysical Research Letters.
Hundreds of miles beneath our feet, floating molten liquid is churning away, driving the planet’s magnetic field like a huge electromagnet. It creates our planet’s north and south magnetic poles. These poles do not correspond to the geographic poles, which mark the ends of Earth’s axis of rotation. In fact, their location changes — daily. What’s more, the magnetic poles even flip from time to time.
Scientists have known this for quite a while and have tracking magnetic pole migrations with high precision for well over a century. This means you shouldn’t be worried about click-bait headlines that announce magnetic pole shifts as something out of the ordinary or even potentially catastrophic. It’s all totally harmless. But what seems to be happening in the last decade is an acceleration in the rate at which the North magnetic pole is moving towards the direction of Siberia and away from Canada.
True North is relative
Historically, researchers recalculate the position of the magnetic North Pole every five years, which is then synced with global navigation systems, such as GPS. The World Magnetic Model is supervised by NOAA and the British Geological Survey, and its most recent update was supposed to happen on January 15 — but it didn’t. The reason behind it is tat NOAA, a US federal agency, is currently inactive due to the ongoing government shutdown.

For most of the previous century, the pole has moved around nine miles each year. However, since the 1990s, the migration has sped up to 35 miles a year. Over the last 150 years, the magnetic pole has crept north over 1,000 kilometers. It’s not clear why this acceleration is occurring due to gaps in our knowledge of how the planet’s core behaves. One leading hypothesis suggests that liquid molten iron under Canada is being dragged toward Siberia. In the meantime, the magnetic South Pole has barely moved, which is another mystery.
What’s more, a geomagnetic pulse occurred beneath South America in 2016. That was right after a 2015 update to the World Magnetic Model, prompting scientists to schedule a revision earlier than the planned 2020 update. This update should have been online this week were it not for the government shutdown. In the meantime, those engaged in navigation requiring great precision around the North Pole will have to wait — and it’s anybody’s guess for how long.
The new model has the North Pole a good 25 miles away from the one previously predicted. This gross discrepancy means that updates in the future will have to be made much more often than before, preferably yearly. Yet normal folks shouldn’t be too worried since the error gets smaller and smaller the farther away you get from the North Pole. If you live in the United States, your compass should be pointing northward as before with reasonable accuracy.
WETENSCHAPIn het Zwitserse Genève bevindt zich nu al de grootste deeltjesversneller ter wereld, maar de natuurkundigen van het Europees Centrum voor Deeltjesonderzoek (CERN) hebben een nog veel groter project in petto. Ze willen een ‘Future Circular Collidor’ (FCC) bouwen, die vier keer groter is dan de de huidige LHC-cyclotron en 24 miljard euro zou kosten. Dat blijkt uit een conceptstudie.
De nieuwe deeltjesversneller zou bestaan uit een 100 kilometer lange tunnel, die deels onder het meer van Genève loopt. De huidige tunnel is 27 kilometer lang. De nieuwe onderzoekscapaciteit zou tegen ten laatste 2040 operationeel moeten zijn.
In een deeltjesversneller worden geladen deeltjes waaruit een atoom bestaat gigantisch versneld – zelfs tot de snelheid van het licht – om fundamenteel onderzoek te doen naar bijvoorbeeld het ontstaan van het heelal. Het CERN heeft momenteel de grootste deeltjesversneller ter wereld, maar andere landen zoals Japan en China hebben eigen bouwplannen.
In het FCC-project, dat in verschillende fases zou worden opgebouwd, zou tot tien keer meer energie kunnen worden geproduceerd dan vandaag, waardoor bijvoorbeeld de omstandigheden van vlak na de oerknal kunnen worden gesimuleerd en mogelijk nieuwe materie kan worden ontdekt.
Een internationaal panel moet wel nog het licht op groen zetten voor de bouw van de Future Circular Collidor.
WETENSCHAPHet katoenzaadje dat in een laboratorium op de maan was ontkiemd, heeft een hevige temperatuurdaling niet overleefd. Volgens de Britse krant The Guardian deed een temperatuur van 170 graden onder nul het plantje, dat aan boord van een Chinese ruimtesonde ontkiemde, de das om.
Het plantje kwam tot leven in een luchtdichte cilinder met dank aan zonlicht op het maanoppervlak. Wetenschappers omschreven de groei van het zaadje als een mijlpaal.
Het zaadje volgde als primeur op een andere historische eerste keer: begin december landde een Chinese sonde op de achterkant van de maan. China doet met behulp van sonde Chang’e 4 onderzoek naar het maanoppervlak. In de cilinder zitten naast het katoenzaadje ook aardappelzaad, gist, en fruitvliegeitjes. Het onderzoeksteam had gehoopt op een mini-ecosysteem.
Volgens professor Xie Gengxin, de Chinese leider van het experiment, had zijn team verwacht dat het zaadje het niet zou overleven. Het is nu nacht op de maan en dat de temperaturen dan sterk dalen, is bekend. Nacht op de maan duurt ongeveer twee weken. Tijdens die periode neemt Chang’e 4 even pauze.
