Pluto might become a planet again because astronomers can’t make up their mind

Hey, remember Pluto? Of course you do! When most of us were brought up in school we learned that there were eight known planets in the Solar System, and Pluto was the one that hung out on the outskirts. Then, in 2006, everything changed and astronomers from around the world declared the Pluto didn’t meet the criteria for being called a planet.

The issue at hand was Pluto’s mass, which just wasn’t high enough to give it what astronomers claimed was necessary for all true planets: a clean orbital path around its host star. Pluto had everything except for this “clear neighborhood” requirement, since debris from the nearby Kuiper belt spilled over into Pluto’s own orbit and the much larger Neptune occasionally tugged on Pluto.

Now, over a decade after that messy list of criteria was cemented, planetary scientist Philip Metzger of the University of Central Florida in Orlando says astronomers should seriously rethink their decision to snub Pluto.

“The IAU definition would say that the fundamental object of planetary science, the planet, is supposed to be a defined on the basis of a concept that nobody uses in their research,” Metzger said in a statement. “And it would leave out the second-most complex, interesting planet in our solar system.”

Metzger’s argument isn’t that Pluto meets the stated requirements for being considered a planet — everyone agrees that Pluto doesn’t fit the description set forth by the International Astronomical Union — but rather that the list of criteria is just plain broken.

“We now have a list of well over 100 recent examples of planetary scientists using the word planet in a way that violates the IAU definition, but they are doing it because it’s functionally useful. It’s a sloppy definition,” he says.

His stance is that the one sticking point for those who wanted to strip Pluto of its planetary status — the “clear” orbit requirement — isn’t useful in determining status at all. Instead, Metzger says, the real defining feature of a planet should be whether or not it is massive enough, and creates enough gravitational force, that it becomes spherical.

“It turns out this is an important milestone in the evolution of a planetary body, because apparently when it happens, it initiates active geology in the body,” he explains.

Whether or not the IAU will take this new argument into account is anyone’s guess. Pluto is presently classified as a “dwarf planet,” but Metzger’s reasoning regarding the seemingly arbitrary definition of a planet seems pretty solid. Perhaps Pluto will once again become the eighth planet in the Solar System.

Alien signals spotted from a galaxy 3 billion light years away
11 hrs ago

Scientists searching for extraterrestrial life say they have spotted 72 mysterious signals from an alien galaxy using artificial intelligence (AI).

The researchers at the SETI (Search for Extraterrestrial Intelligence) Institute discovered the unusual signals when examining 400 terabytes of radio data from a dwarf galaxy three billion light years away from Earth.

Almost all artificial intelligence technology involves automating data analysis, combing through huge data sets to identify patterns or unusual occurrences.

The signals they spotted - fast radio bursts (FRBs) - are bright and quick pulses which were first discovered in 2007 and are believed to come from distant galaxies, although it is not yet know what causes them.

"The nature of the object emitting them is unknown," SETI said, adding: "There are many theories, including that they could be the signatures of technology developed by extraterrestrial intelligent life."

Last year, scientists at Harvard University suggested that FRBs could result from energy leaks from powerful transmitters built by alien civilisations in order to send giant light sail ships on interstellar voyages.

A light sail would use the tiny amount of pressure exerted by light to produce a small but constant acceleration which allows a spacecraft to reach a great speed.

The FRBs were detected in data collected by the Green Bank Telescope, part of the US Radio Quiet Zone, where wireless communications signals are banned to prevent interference with the telescopes.

Gerry Zhang, a PhD student at Berkeley, developed the machine-learning algorithm used to examine the 400tb of data, in which another researcher had already identified 21 FRBs.

"Gerry's work is exciting not just because it helps us understand the dynamic behavior of FRBs in more detail," said SETI's Dr Andrew Siemion, "but also because of the promise it shows for using machine learning to detect signals missed by classical algorithms."

Dr Siemion added: "These new techniques are already improving our sensitivity to signals from extraterrestrial technologies."

The results of their research have been accepted for publication in the Astrophysical Journal.

'It's all very fishy': A New Mexico solar observatory was closed without warning for a 'security threat.' No one knows why

https://www.deseretnews.com/article/900032503/its-all-very-fishy-a-new-mexico-solar-observatory-was-closed-without-warning-for-a-security-threat-no-one-knows-why.html

SALT LAKE CITY — A solar observatory in New Mexico reopened Monday after a 10-day closure for reasons that haven’t been thoroughly explained, according to CNN.

Aliens, though, weren’t involved.

What happened: On Sept. 6, the Sunspot Solar Observatory in New Mexico was shut down by its operator, the Association of Universities for Research in Astronomy, according to NPR.

- No reason was given for the closure. Later, it was reported that a security threat led to the closure. The security threat remains unclear.

-Those who work at the observatory and who live on the campus were randomly asked to leave. The location’s post office also shut down for the 10 days.

- Local newspapers reported suspicious activity at the facility involving government agents and military vehicles.


Confusion: Local officials and residents were bewildered by the sudden closure.


- “Nothing really happens here very much. And since nobody knows, it could be almost anything,” one resident told KRQE.

The Otero County sheriff told The Alamogordo Daily News he was made aware of the closure. But he didn’t receive any official reason.

- "The FBI is refusing to tell us what's going on," Sheriff Benny House told The Alamogordo Daily News shortly after the closure. "We've got people up there (at Sunspot) that requested us to standby while they evacuate it. Nobody would really elaborate on any of the circumstances as to why. The FBI were up there. What their purpose was nobody will say."

- "But for the FBI to get involved that quick and be so secretive about it, there was a lot of stuff going on up there," House added. "There was a Blackhawk helicopter, a bunch of people around antennas and work crews on towers but nobody would tell us anything."

John Varsik, a data scientist and telescope operator at California's Big Bear Solar Observatory, told BuzzFeed News that, "nothing like this has ever happened before at an observatory.”

- “It’s all very fishy," he said.

Reason for closure: AURA, the consortium and the National Science Foundation, released a statement that said a security threat led to the closure.

- "AURA has been cooperating with an ongoing law enforcement investigation of criminal activity that occurred at Sacramento Peak. During this time, we became concerned that a suspect in the investigation potentially posed a threat to the safety of local staff and residents. For this reason, AURA temporarily evacuated the facility and ceased science activities at this location.

- "The decision to vacate was based on the logistical challenges associated with protecting personnel at such a remote location, and the need for expeditious response to the potential threat. AURA determined that moving the small number of on-site staff and residents off the mountain was the most prudent and effective action to ensure their safety."

Back to normal: The observatory returned to normal operations on Monday.

NASA's New Planet Hunter Just Found Its 1st Alien World — an Evaporating 'Super-Earth'

https://www.space.com/41882-nasa-tess-first-exoplanet-evaporating-super-earth.html

by Charles Q. Choi, Space.com Contributor | September 19, 2018 07:31pm ET
NASA's newest planet-hunting mission has reported detecting its first alien world — a "super-Earth" that is likely evaporating under the heat from its star, a new study finds.


The Transiting Exoplanet Survey Satellite (TESS) launched to Earth orbit on April 18 atop a SpaceX Falcon 9 rocket. The space telescope is analyzing several hundred thousand of the brightest stars in the sun's neighborhood, looking for tiny dips in brightness caused by the passage (or "transit") of orbiting planets as small as Earth across the faces of those stars.

The scientists have used TESS data to discover a new planet around the star Pi Mensae, also known as HD 39091, which is located about 59.5 light-years from Earth in the constellation Mensa, the table. Pi Mensae is a yellow dwarf star like the sun and the second-brightest among stars known to have transiting exoplanets.

Previous research had already spotted a gas giant around Pi Mensae that's about 10 times more massive than Jupiter. This exoplanet, named Pi Mensae b, has a highly oval-shaped "eccentric" orbit that carries it up to 3 astronomical units (AU) nfrom its star. (One AU is the average distance between Earth and the sun — about 93 million miles, or 150 million kilometers.)


Now, scientists have detected a new world around Pi Mensae — one about 2.14 times Earth's diameter and 4.82 times Earth's mass. This super-Earth, h dubbed Pi Mensae c, orbits about 0.07 AU from its star, or more than 50 times closer than Mercury does the sun. (As the name implies, Super-Earths are planets a bit bigger than our own, harboring from about 2 to 10 Earth masses.)

Pi Mensae c is a super-Earth, a class of planets slightly larger and more massive than our own world.


The density of Pi Mensae c is consistent with a picture where "the entire planet is made of water," study lead author Chelsea Huang, of the Massachusetts Institute of Technology, told Space.com. However, "it is more likely to have a rocky core and an extended atmosphere made of hydrogen and helium," she said. "We also think this planet might be evaporating right now, given the intense irradiation it gets from its host star."

Future research can investigate the odd configuration of Pi Mensae's two known planets. The oval-shaped orbit of Jupiter-like Pi Mensae b stands in stark contrast to the circular orbit of Jupiter. This suggests that "something must have happened in the history of this planetary system to excite the orbit of the distant Jupiter-like planet," Huang said. "If so, how did the inner system survive? These questions still need further investigation, and understanding them will tell us a lot of planet-formation theory."

TESS follows in the footsteps of NASA's iconic Kepler space telescope, which has discovered about 70 percent of the 3,800 known exoplanets to date, also using the transit method. TESS will exceed Kepler's exoplanet haul if all goes according to plan, TESS team members have said.

The scientists detailed their findings online Sept. 16 in a paper submitted to The Astrophysical Journal Letters. You can read it at the online preprint site arXiv.org.

Spooky Skull-Like ‘Death Comet’ Asteroid To Zip Past Earth Just After Halloween
It’s also been called “The Great Pumpkin” asteroid.

https://www.huffingtonpost.com/entry/skull-asteroid-death-comet-halloween_us_5bac637be4b082030e782564?ncid=engmodushpmg00000006

There’s a different kind of Halloween sequel in the works, and it’s coming soon to the skies near Earth.

A skull-like asteroid that passed Earth in October 2015 is coming back for another visit in early November. Officially named 2015 TB145, the asteroid has been called The Great Pumpkin by NASA because of its Halloween flyby three years ago.

2015 TB145 has also been described as a “death comet” because it’s believed to be a dead comet and because of its skull shape, which was picked up on radar images from the Arecibo Observatory in Puerto Rico:

“We found that the object reflects about 6 percent of the light it receives from the sun,” Vishnu Reddy, a research scientist at the Planetary Science Institute, said in a 2015 news release. “That is similar to fresh asphalt, and while here on Earth we think that is pretty dark, it is brighter than a typical comet which reflects only 3 to 5 percent of the light. That suggests it could be cometary in origin ― but as there is no coma evident, the conclusion is it is a dead comet.”

Despite the spooky appearance and nicknames, 2015 TB145 will pose no threat to life on Earth. After flying within 310,000 miles of the planet three years ago, the closest the comet will come this time around is 24 million miles on Nov. 11, Mother Nature Network reported.

Tonight SpaceX did another twilight launch from Vandenberg. It deployed some satellites into orbit, and the first stage landed back at the launch complex.

You could see it where I was, but the sky was somewhat hazy due to smoke from a nearby fire. A buddy of mine got a good view from his house in L.A.:

Toward the end of the clip, you can see the first stage returning to Vandenberg.

They also posted a version of this on Facebook. It doesn't have the watermark, but it may not be available to everyone:

Chinese city plans 'artificial moon' to light up skies
08:22, Oct 19 2018

A city in China is hoping to launch an "artificial moon" to light up the night skies in 2020.

The southwestern city of Chengdu will be the focus of an illumination satellite, reports the People's Daily.

The artificial moon will be eight times brighter than the real Moon and will be able to light an area with a diameter of up to 80 kilometres.

It is hoped that the "artificial moon" will be ready in 2020 (file photo).

Wu Chunfeng, chairman of Chengdu Aerospace Science and Technology Microelectronics System Research Institute, made the announcement at a recent conference and said the new moon could replace some street lights.

IFLScience reports that "the moon would be a satellite with a special coating that would reflect the light of the Sun onto Chengdu during the night".

There are concerns that the light will affect animal behaviour.

However, Kang Weimin, director of the Institute of Optics, School of Aerospace, Harbin Institute of Technology, said the light would be similar to dusk and that it shouldn't upset animal routines.

Exact details about the new moon and the launch date haven't been released, but Wu said scientists have been working on the idea for years and that technology has finally matured.

more info on the super massive black hole

New image shows signs of supermassive black hole
22:47, Nov 03 2018

Image
ESO
This visualisation uses data from simulations of orbital motions of gas swirling around at about 30 per cent of the speed of light on a circular orbit around the black hole.

Astronomers have gained an image of the tell-tale signs of Sagittarius A*, the supermassive black hole at the centre of our galaxy.

The new image was produced from data got by combining the infrared light measured by four telescopes in Chile, part of the European Southern Observatory's (ESO) Very Large Telescope.

ESO was able to to observe flares of infrared radiation coming from gases very close to the black hole's event horizon, the point of no return beyond which anything, including light, is sucked into the monster.

The black hole's huge gravitational pull forces the gases and other material close to the event horizon to rotate around it at astonishing speed.

"New observations show clumps of gas swirling around at about 30 per cent of the speed of light on a circular orbit just outside its event horizon - the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole," a statement from ESO said.

"The observed flares provide long-awaited confirmation that the object in the centre of our galaxy is, as has long been assumed, a supermassive black hole."

Sagittarius A*, like other supermassive black holes, was probably formed during the earliest days of the universe.

It was about 4 million times as hefty as the sun but only 18 times as large, and it sat on space-time like a bowling ball on a trampoline, warping everything around it.

Under these extreme conditions, the laws of physics are pushed to their limits: Gravity is twisted; light is torn apart; matter is made to vanish from existence.

As Sagittarius A* slurps up matter from the boiling buffet of gas, dust and bits of stars swirling around it, it flings huge amounts of material back into space: X-rays, radio waves, jets of ultrahot gas.

Paradoxically, all this activity makes the black hole one of the brightest things in the Milky Way - and further obscures the darkness inside.

Pluto explorer to bring in the new year exploring the most distant world yet
20:53, Dec 29 2018

The spacecraft team that brought us close-ups of Pluto will ring in the new year by exploring an even more distant and mysterious world.

Nasa's New Horizons spacecraft will zip past the scrawny, icy object nicknamed Ultima Thule (TOO-lee) soon after the stroke of midnight (about 6.30pm NZ time).

1.6 billion kilometres beyond Pluto and an astounding 6.4b km from Earth, Ultima Thule will be the farthest world ever explored by humankind. That's what makes this deep-freeze target so enticing; it's a preserved relic dating all the way back to our solar system's origin 4.5 billion years ago. No spacecraft has visited anything so primitive.

"What could be more exciting than that?" said project scientist Hal Weaver of Johns Hopkins University, part of the New Horizons team.

Lead scientist Alan Stern of Southwest Research Institute in Boulder, Colorado, expects the New Year's encounter to be riskier and more difficult than the rendezvous with Pluto: The spacecraft is older, the target is smaller, the flyby is closer and the distance from us is greater.

NEW HORIZONS

Nasa launched the spacecraft in 2006; it's about the size of a baby grand piano. It flew past Pluto in 2015, providing the first close-up views of the dwarf planet. With the wildly successful flyby behind them, mission planners won an extension from Nasa and set their sights on a destination deep inside the Kuiper Belt. As distant as it is, Pluto is barely in the Kuiper Belt, the so-called Twilight Zone stretching beyond Neptune. Ultima Thule is in the Twilight Zone's heart.

Image
NASA
A combination of images of Pluto's surface captured by the New Horizons spacecraft on its maiden voyage in 2015.

ULTIMA THULE

This Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote. In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world. When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.

ARE WE THERE YET?

New Horizons will make its closest approach in the wee hours of January 1 - 12.33am EST (6.33pm NZ time). The spacecraft will zoom within 3500km of Ultima Thule, its seven science instruments going full blast. The coast should be clear: Scientists have yet to find any rings or moons around it that could batter the spacecraft. New Horizons hurtles through space at 50,700 kph, and even something as minuscule as a grain of rice could demolish it. "There's some danger and some suspense," Stern said at a fall meeting of astronomers. It will take about 10 hours to get confirmation that the spacecraft completed - and survived - the encounter.

POSSIBLY TWINS

Scientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, it's likely 32km long at most. Envision a baked potato. "Cucumber, whatever. Pick your favourite vegetable," said astronomer Carey Lisse of Johns Hopkins. It could even be two bodies connected by a neck. If twins, each could be 15km to 20km in diameter.

MAPPING MISSON

Scientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth. As for colour, Ultima Thule should be darker than coal, burned by eons of cosmic rays, with a reddish hue. Nothing is certain, though, including its orbit, so big that it takes almost 300 of our Earth years to circle the sun. Scientists say they know just enough about the orbit to intercept it.

COMPARING FLYBYS

New Horizons will get considerably closer to Ultima Thule than it did to Pluto: 3500km versus 12,500km. At the same time, Ultima Thule is 100 times smaller than Pluto and therefore harder to track, making everything more challenging. It took 4 hours, each way, for flight controllers at Johns Hopkins' Applied Physics Lab in Laurel, Maryland, to get a message to or from New Horizons at Pluto. Compare that with more than six hours at Ultima Thule.

WHAT'S NEXT?

It will take almost two years for New Horizons to beam back all its data on Ultima Thule. A flyby of an even more distant world could be in the offing in the 2020s, if Nasa approves another mission extension and the spacecraft remains healthy. At the very least, the nuclear-powered New Horizons will continue to observe objects from afar, as it pushes deeper into the Kuiper Belt. There are countless objects out there, waiting to be explored.

Nasa boldly goes where no-one, except Mork, has gone before
MARCIA DUNN·08:19, Jan 02 2019

Nasa's New Horizons spacecraft has survived the most distant exploration of another world, a tiny, icy object 4 billion miles away that looks to be shaped like a peanut or bowling pin.

Word of success came 10 hours after the middle-of-the-night encounter, once flight controllers in Maryland, US received word from the spacecraft late Tuesday morning. Cheers erupted at Johns Hopkins University's Applied Physics Laboratory, home to Mission Control, as mission operations manager Alice Bowman declared: "We have a healthy spacecraft.''

A huge spill-over crowd in a nearby auditorium joined in the loud celebration, cheering each green, or good, status update. Scientists and other team members embraced, while hundreds of others gave a standing ovation.

"I don't know about all of you, but I'm really liking this 2019 thing so far,'' lead scientist Alan Stern of Southwest Research Institute said to applause. "I'm here to tell you that last night, overnight, the United States spacecraft New Horizons conducted the farthest exploration in the history of humankind, and did so spectacularly.''

New Horizons zoomed past the small celestial object known as Ultima Thule. Scientists said it will take nearly two years for New Horizons to beam back all its observations of Ultima Thule, a full billion miles (1.6 billion kilometres) beyond Pluto. At that distance, it takes six hours for the radio signals to reach Earth.

Guests cheer as the New Horizons team members receive signals from the spacecraft that it is healthy.

Scientists did not want to interrupt observations as New Horizons swept past Ultima Thule - described as a bullet intersecting with another bullet - so they delayed radio transmissions. The spacecraft is believed to have come within 2200 miles (3500km) of Ultima Thule.

Weary from dual countdowns late Monday and early Tuesday, the New Horizons team members were visibly anxious as they reassembled in late morning. "Happy New Year again,'' they bid one another. But the hundreds of spectators went wild nonetheless when the good news came in.

New Horizons' 2015 encounter with Pluto was the most distant exploration until Tuesday. The Ultima Thule rendezvous was more complicated, given its 4 billion-mile (6.4 billion-kilometre) distance from Earth, the much closer gap between the spacecraft and its target, and all the unknowns surrounding Ultima Thule.

Based on rudimentary pictures snapped just hundreds of thousands of miles (kilometres) before the 12.33am close approach, Ultima Thule is decidedly elongated -about 22 miles by 9 miles (35km by 15km). Scientists say there are two possibilities: Ultima Thule is either one object with two connected lobes, sort of like a spinning bowling pin or peanut still in the shell, or two objects orbiting surprisingly close to one another. A single body is more likely, they noted. An answer should be forthcoming Wednesday, once new and better pictures arrive. The best colour close-ups, though, won't be available until later in January and February.

The icy rock has been in a deep-freeze preservation state since the formation of our solar system 4.5 billion years ago. Scientists hope to learn about those origins through New Horizons' observations deep inside the so-called Kuiper Belt, or frozen Twilight Zone, on the fringes of the solar system.

New Horizons will continue to zoom farther away. The hope is that the mission, now totaling US$800 million, will be extended yet again and another target will be forthcoming sometime in the 2020s.

Ultima Thule is the first destination to be reached that was not even known until after the spacecraft's launch. New Horizons rocketed from Cape Canaveral, Florida, in 2006.

Astronomers accidentally find a tiny galaxy that is nearly as old as the universe itself

Scientists have accidentally found a tiny, ancient "living fossil" galaxy – and it was hiding surprisingly close to us.

The compact collection of stars is almost as old as the universe itself, according to the astronomers who found it. And it could offer an opportunity to look back into the beginning of the cosmos.

The tiny galaxy is only 30 million light-years away but is so dark and distant that it was only found while astronomers were looking for something else entirely.

Scientists made the discovery while they were using the Hubble Space Telescope to look at the white dwarf stars in a globular cluster known as NGC 672. They had hoped to use those stars to measure the age of the cluster.

But as they did so they spotted the small set of stars on the edge of the area they were observing. After analysis, they found the stars did not belong to the cluster they were looking at – a part of the Milky Way – but were in fact millions of light-years away from it.

The new discovery has been nicknamed Bedin 1 and is a small but long galaxy. It measures only 3000 light-years across even at its longest point, making it just a fraction of the size of our own Milky Way.

It is dark as it is feint. Together, those properties led astronomers to classify it as what is called a dwarf spheroidal galaxy.

Such galaxies are defined by their small size and dim light, as well as their lack of dust and old stellar populations. Researchers have found 36 galaxies of this kind in our nearby area, 22 of which are satellite galaxies around our own Milky Way.

Dwarf spheroidal galaxies are not uncommon, but the newly discovered one is strange in a number of ways. It is extremely isolated, about 30 million light-years from the Milky Way and two million light-years from its nearest possible host – making it the most isolated of any small dwarf galaxy ever found.

From studying its stars, scientists found that the galaxy is around 13 billion years old, making it nearly as old as the entire universe. Because it is so distant from any other galaxies – and so has been left largely undisturbed – as well as its old age, the astronomers refer to Bedin 1 as a fossil from the beginning of the cosmos.

NASA denies scientists have discovered how to transform the class of thermochemical reactions once known as "irreversible processes" so as to actually reverse them.
C. Counterfly, 2-1-19

An anonymous "visitor" from an unspecified time in the future has been quoted: "Once we acquired the technique, the whole problem became trivial. We are here among you as seekers of refuge from our present-your future-a time of worldwide famine, exhausted fuel supplies, terminal poverty-the end of the capitalistic experiment. Once we came to understand the simple thermodynamic truth that Earth's resources were limited, in fact soon to run out, the whole capitalistic illusion fell to pieces. Those of us who spoke the truth were denounced as heretics, as enemies of the prevailing economic faith. Like religious dissenters of an earlier day, we were forced to migrate, with little choice but to set forth upon that dark fourth-dimensional Atlantic known as time."

It is by way of visual conduits that they cross over, for brief periods, to our own time and space. It's our innocence that they are after. They have descended on our shores to capture our innocence, and take it away with them into futurity. A NASA spokesperson was quick to deny the claims and reminded us of the great advances being made here on Earth in the field of space photography.
