Scientists Just Found the Fastest-Growing Black Hole. Here's How Fast It 'Eats'

Researchers used newly released data from the European Space Agency's Gaia satellite to confirm that the brightly shining object is a black hole, which appears to have been the mass of about 20 billion suns when the light was released and was growing by 1 percent every million years, researchers said in a statement released today (May 15).

"This black hole is growing so rapidly that it's shining thousands of times more brightly than an entire galaxy, due to all the gases it sucks in daily that cause lots of friction and heat," Christian Wolf, an astronomer at the Australian National University and first author on the new research, said in the statement.

Luckily, though, the black hole is far enough away that it likely released its light more than 12 billion years ago, the researchers said. The energy it emits is mostly ultraviolet light, but it also releases X-rays. "Again, if this monster was at the center of the Milky Way, it would likely make life on Earth impossible with the huge amounts of X-rays emanating from it," Wolf said.

Because of its distance and the expansion of space, that light had shifted into the near-infrared during its billions-of-years journey. Wolf and his colleagues spotted the light with the SkyMapper telescope at the ANU Siding Spring Observatory. They then used the Gaia satellite to measure that the object was sitting still, thereby also confirming that it was incredibly distant and likely a supermassive black hole, the researchers said. Then, another ANU telescope measured the wavelengths released from the object to verify its composition.

Pluto does not live a lonely life
OSSOS. VII. 800+ Trans-Neptunian Objects

Abstract

The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013─2017 with the Canada─France─Hawaii Telescope, surveyed 155 deg2 of sky to depths of m r = 24.1─25.2. We present 838 outer solar system discoveries that are entirely free of ephemeris bias. This increases the inventory of trans-Neptunian objects (TNOs) with accurately known orbits by nearly 50%. Each minor planet has 20─60 Gaia/Pan-STARRS-calibrated astrometric measurements made over 2─5 oppositions, which allows accurate classification of their orbits within the trans-Neptunian dynamical populations. The populations orbiting in mean-motion resonance with Neptune are key to understanding Neptune’s early migration. Our 313 resonant TNOs, including 132 plutinos, triple the available characterized sample and include new occupancy of distant resonances out to semimajor axis a ∼ 130 au. OSSOS doubles the known population of the nonresonant Kuiper Belt, providing 436 TNOs in this region, all with exceptionally high-quality orbits of a uncertainty σ a ≤ 0.1% they show that the belt exists from a ≳ 37 au, with a lower perihelion bound of 35 au. We confirm the presence of a concentrated low-inclination a ≃ 44 au “kernel” population and a dynamically cold population extending beyond the 2:1 resonance. We finely quantify the survey’s observational biases. Our survey simulator provides a straightforward way to impose these biases on models of the trans-Neptunian orbit distributions, allowing statistical comparison to the discoveries. The OSSOS TNOs, unprecedented in their orbital precision for the size of the sample, are ideal for testing concepts of the history of giant planet migration in the solar system.

Scientists just discovered something very special about Jupiter’s lightning
Jupiter is a massive, swirling mass of towering storm clouds, and anyone who lives on Earth knows that storms are fantastic at producing lightning. When NASA sent its Voyager 1 spacecraft on its trip through our Solar System, its flyby of Jupiter revealed that Jupiter does indeed have lightning, but it wasn’t producing the same kinds of radio signals that scientists are familiar with from lightning here on Earth. Now, nearly four decades later, NASA finally knows why.

NASA researchers just published a new paper in Nature that describes how they used data from the Juno probe to solve the mystery of Jupiter’s strange lightning, and it reveals that the planet’s storms produce flashes that are both very similar and also completely different from lightning on Earth.

“In the data from our first eight flybys, Juno’s MWR detected 377 lightning discharges. They were recorded in the megahertz as well as gigahertz range, which is what you can find with terrestrial lightning emissions,” Brown explains. “We think the reason we are the only ones who can see it is because Juno is flying closer to the lighting than ever before, and we are searching at a radio frequency that passes easily through Jupiter’s ionosphere.”

NASA says the lightning distribution on Jupiter is “inside out” compared to Earth. The lightning originates at Jupiter’s poles, rather than distributed across its surface, and the researchers attribute that to Jupiter’s distance from the Sun. They think that, because Jupiter’s atmosphere is stable near its equator thanks to warmth from the Sun, the lightning is forming in the much less stable air rising near its poles from within the planet. Neat!

Opportunity, one of the two solar powered rovers that landed on Mars in 2004 with an expected lifetime of 90 days and a hoped-for-if-everything-goes-ridiculously-right-lifetime of two or three times that duration, is now waiting out a dust storm that threatens to end its improbably long and successful science mission.

Doug Ellison, a British multimedia producer who parlayed his interest in processing publicly available images downloaded from Mars into a rover operations job at the Jet Propulsion Laboratory, has posted a series of interesting materials on his twitter feed which provide the engineering background for understanding Opportunity's peril.

Giant Black Hole Swallows a Star and Belches Out a Superfast Particle Jet
A decade-long international effort to track a star’s death by black hole could lift the veil on galaxy formation in the early universe


Marshaling a decade’s worth of data from telescopes around the world, scientists have captured new details of a gargantuan black hole feasting on a hapless star, watching as the black hole consumed its prey and burped out a jet of material moving at a significant fraction of the speed of light. The results are published in the June 14 edition of Science, and could help researchers better understand how black holes grow and influence their galactic surroundings.

“Never before have we been able to directly observe the formation and evolution of a jet from one of these events,” says study co-author Miguel Pérez-Torres of the Institute of Astrophysics of Andalusia in Spain.

Both had been hunting for supernovae in the vicinity of Arp 299’s colliding galactic cores, a dust-shrouded region filled with clouds of gas and newborn massive stars generated by the ongoing merger. And a supernova was, at first, exactly what they thought they found. These cataclysmic stellar explosions are particularly bright in visible light and in x-rays—except in Arp 299’s murky center most of that light would be absorbed by dust and reradiated in the infrared; the remnant would then leak out as radio waves. But follow-up infrared observations with NASA’s Spitzer Space Telescope showed the source was far too bright to be a supernova, blazing with light that would outshine a typical small galaxy by several 100-fold. That suggested the source was not a supernova at all, but rather a tidal disruption event (TDE), a star being torn apart by a supermassive black hole.

In a TDE roughly half of the ripped-up star is flung away from the black hole whereas the other half plunges to its doom, piling up around the hole’s maw in a whirling disk of glowing debris that can be mistaken for a supernova. There is no mistaking, however, the other signature of a TDE: twin jets of star stuff ejected from near the black hole at nearly light-speed by intense magnetic fields twisting and breaking like rubber bands. Ramming into the diffuse gas of the interstellar medium, the jets would produce copious radio waves potentially visible from Earth. So Mattila, Pérez-Torres and 34 additional collaborators organized an international campaign using a global network of radio telescopes to obtain high-resolution radio images of the source, patiently, periodically monitoring its size and shape in search of a jet.

U.S. to resume manned space flights
By Mark Armstrong • last updated: 04/08/2018

NASA has named nine astronauts for the first manned space launches from U.S. soil since the space shuttle programme ended in 2011.

NASA
3:46 AM - Aug 4, 2018

The announcement is a milestone in the U.S. space programme, with its shift to the private sector for ferrying cargo and astronauts to the International Space Station.

Up to now, NASA has had to rely on Russia to fly them there. The new astronauts will travel on a spacecraft developed by entrepreneur Elon Musk's SpaceX and Boeing Co, crewing first the test flights, and then missions involving both Boeing's CST-100 Starliner and SpaceX's Crew Dragon.
Donald J. Trump @realDonaldTrump
NASA, which is making a BIG comeback under the Trump Administration, has just named 9 astronauts for Boeing and Spacex space flights. We have the greatest facilities in the world and we are now letting the private sector pay to use them. Exciting things happening. Space Force!

12:43 AM - Aug 4, 2018
President Donald Trump said in a tweet that they had the " the greatest facilities in the world and are now letting the private sector pay to use them."

NASA says its critical to understanding the challenges of long-duration space flight, for a sustainable presence on the Moon and for deep-space missions, including to Mars.

Why This Year’s Perseid Meteor Shower Promises to Be Especially Dazzling

AUGUST 8, 2018

If stargazing had a Billboard Hot 100 chart, the Perseids would be the Beatles. But while the Perseid meteor shower always knows how to put on a show, NASA meteor expert Bill Cooke recently told Sarah Lewin of Space.com that this year, the Perseids will be treating viewers to, essentially, Liverpool Cavern Club-caliber performances.

In part, astronomers can thank a fortuitously timed moon cycle that will leave the skies darker than usual. When the Perseids peak this weekend, they will offer crisp views of about 60-70 shooting stars every hour. While the best time to catch them in the act will likely be late into the evenings of August 11 and 12, Cooke tells Lewin, some speckles will be visible as early as August 9.

Ancient ‘Monster Galaxy’ Is Forming Stars a Thousand Times Faster Than the Milky Way

Chile’s Atacama Large Millimeter/submillimeter Array (ALMA) has observed a galaxy that looks nothing like what researchers expected. It’s forming stars at an absolutely incredible rate.

The “Monster Galaxy”, also known as COSMOS-AzTEC-1, formed just 2 billion years after the Big Bang, and it turns more than a thousand Suns worth of gas into stars each year. Scientists still don’t understand these early galaxies very well, but now they have some new information that can shed light on why they form stars so blisteringly fast.

Essentially, the clumpy gas inside the galaxy has a stronger gravitational pull on itself than the force of the galaxy’s rotation or repulsion from stars and supernovae, according to the observations published today in Nature.

Scientists discovered galaxies like AzTEC-1 only two decades ago, according to the paper, and have studied them to try and understand extreme starburst events. By extreme, I mean the galaxy is forming stars a thousand times faster than the Milky Way does. These ancient galaxies are thought to be the ancestors of today’s elliptical galaxies, according to a press release.

While there are, rightly really, conspiracy theories spinning around this story, I am very curious to see the outcome:
Unexplained 'Security Issue' Keeps National Solar Observatory Facility Shuttered
By Mike Wall, Space.com Senior Writer

It's been more than a week, and a National Solar Observatory (NSO) facility in New Mexico is still closed for an undisclosed "security issue."

The NSO's Sunspot Solar Observatory, on Sacramento Peak in the southern part of the state, was evacuated last Thursday (Sept. 6), as was a nearby post office, according to the Albuquerque Journal. FBI agents have reportedly been investigating the site, and they're apparently keeping local law-enforcement personnel in the dark.

The Association of Universities for Research in Astronomy (AURA), which manages the Sunspot observatory with funding from the U.S. National Science Foundation, hasn't said much, either. The organization released a statement saying that AURA "is addressing a security issue" at Sunspot "and has decided to temporarily vacate the facility as a precautionary measure until further notice." AURA "is working with the proper authorities on this issue," the statement adds, without specifying who those authorities are.

And we may not get answers anytime soon. At 2 p.m. EDT (1800 GMT) today (Sept. 14), AURA Corporate Communications Coordinator Shari Lifson sent out an email update, which stated that AURA "has decided that the observatory will remain closed until further notice due to an ongoing security concern."

Mysterious Evacuation Of Solar Observatory Overlooking White Sands Smells Like Espionage
The bizarre incident has spurred outlandish theories, but based on what we know and the location, there are more plausible explanations.
BY TYLER ROGOWAY AND JOSEPH TREVITHICK SEPTEMBER 13, 2018
:snippity:

It seems more plausible that a foreign operative or an operative working on a foreign government's behalf might have been able to install an antenna/sensor apparatus onto the top of a structure that is part of the facility and within line-of-sight of the valley below without anyone noticing. This could allow them to persistently gather electronic intelligence on whatever might be happening on, around, and over White Sands and at Holloman. With the capabilities of modern electronics and batteries, it's possible that such a system wouldn't even need to be hard wired.

For instance, check out this 360 photo of a publically accessible viewpoint and weather station adjacent to the main solar telescope tower up at Sacremento Peak. The small building is covered with antennas and electronics which have a perfectly clear line of sight to the valley below. Clandestinely placing a sensor package here that is able to collect certain emissions while blending in with the clutter seems like a relatively rudimentary task—hiding in plain sight if you will.

This is just one area of a fairly large complex of observatories and other buildings, many of which are in disuse, but which may already be adorned with antennas and other electronics and have an unobstructed line-of-sight towards White Sands. Otero County Sheriff House's comment in which he states there were officials and workmen inspecting towers and antennas could indicate that there were looking for just such a device.

Individuals looking to spy on Holloman or White Sands could have been using the local post office to send copies of that information to their handlers or to an intermediate location, as well. A suspect could even work or live up there. As such, the FBI or other agencies could have decided to temporarily shut down its operations in order to comb it for evidence, even just as a basic precaution.
:snippity:
The incident is very strange, to say the least. It sounds more like the opening of an '80s science fiction adventure film than something that is actually happening and it has begun to trigger all types of outlandish theories. These include that the telescope identifying a world-changing solar flare or spotted proof of alien life in our solar system. Both of these suppositions seem to have been shot down by the director of the telescope facility, who said his team would gladly release the data the telescope was collecting before feds arrived.

But something is going on out of the ordinary up there, and based on what we do know, it seems like espionage is a real possibility.

The FBI referred all questions to the group that manages the site, the Association of Universities for Research in Astronomy. Officials there say they're working with authorities.

The association said in an update Friday that it has "decided that the observatory will remain closed until further notice due to an ongoing security concern. The rest of the National Solar Observatory facilities remain open and are operating normally."
The vagueness continued to fuel speculation on social media.

Yes... by making the sun hotter they're making us think it's C02 so we stop burning oil so they can take it... like Trump wants to take Iraq oil.. so Trump must be colluding and it's a big coverup to protect him because the telescope has the proof.

Disclosure is imminent!! Or, a crazy Q-anoner saw a pizza slice in a sun image...
(Statement from AURA)
On September 6th the Association of Universities for Research in Astronomy (AURA) and the National Science Foundation (NSF) made the decision to temporarily vacate the Sunspot Solar Observatory at Sacramento Peak, New Mexico as a precautionary measure while addressing a security issue. The facility closed down in an orderly fashion and is now re-opening. The residents that vacated their homes will be returning to the site, and all employees will return to work this week. AURA has been cooperating with an on-going 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 vacated 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. In light of recent developments in the investigation, we have determined there is no risk to staff, and Sunspot Solar Observatory is transitioning back to regular operations as of September 17th.
Given the significant amount of publicity the temporary closure has generated, and the consequent expectation of an unusual number of visitors to the site, we are temporarily engaging a security service while the facility returns to a normal working environment. We recognize that the lack of communications while the facility was vacated was concerning and frustrating for some. However, our desire to provide additional information had to be balanced against the risk that, if spread at the time, the news would alert the suspect and impede the law enforcement investigation. That was a risk we could not take.

This has bothered me from the start. We knew that the facility was shut and there was an ongoing investigation and so did the "suspect/s" .... so why not disclose for the start it was about the observatory's internet be used for child porn? ...
The mysterious 11-day closure of a New Mexico solar observatory stemmed from an FBI investigation of a janitor suspected of using the facility’s wireless internet service to send and receive child pornography, federal court documents showed on Wednesday.
I don't buy it.
