Scientists to announce "groundbreaking result" in black hole telescope project
BY BRIAN PASCUS

Astronomers say a major announcement is on the way based on findings from the international Event Horizon Telescope project, which experts believe could be the first-ever photographs to show the surroundings of a black hole. On Wednesday, April 10, the Event Horizon Telescope team will be holding multiple press conferences around the world to announce a "groundbreaking result" in their study of black hole environments.

The Event Horizon Telescope is an international collaboration that aims to capture images of black hole areas by linking up various radio dishes from around the world that together create a virtual telescope roughly the size of planet Earth. The project began capturing data in 2006.


Scientists from the U.S., France, and the Netherlands will be making their announcement Wednesday at the National Press Club in Washington, D.C, while related press conferences will occur simultaneously in Brussels, Santiago, Shanghai, Taipei, and Tokyo.

Telescope project aims to generate enough magnifying power to bring black hole environments into focus, allowing for the study of their characteristics. Because black holes do not emit light, they cannot be seen and are technically invisible. Instead, the Event Horizon Telescope looks to study areas surrounding a black hole, namely the gas which radiates around it due to its intensely strong gravity pull, in an attempt to capture images of its general dynamics.

Black holes are regions within the fabric of outer space that have such strong gravitational pulls that nothing, whether it be mass particles or light waves, can escape from it. The point within the black hole which nothing can escape from is called its event horizon. Scientists believe black holes form out of the remains of recently collapsed stars, which pull in all mass and light from its surrounding areas to grow bigger, and that supermassive black holes form the center of most galaxies, creating gravitational forces that link the various stars together.

Einstein was right: Scientists detect gravitational waves in breakthrough
The size of any black hole is always proportionate to its mass, so some may only be a few times the mass of our sun, which are called stellar black holes, while others are millions or billions of times the mass of the sun — supermassive black holes believed to anchor the constellations of galaxies.


The Event Horizon Telescope project has pinpointed two supermassive black holes to study: Sgr A*, which lays at the heart of our Milky Way galaxy, and M87, a giant elliptical galaxy located in the constellation Virgo.

Eureka! Black Hole Photographed for 1st Time
By Mike Wall 10 April 2019


Black holes have finally been dragged out of the shadows.

The Event Horizon Telescope, a planet-scale array of eight ground-based radio telescopes forged through international collaboration, captured this image of the supermassive black hole in the center of the galaxy M87 and its shadow.

Black holes have finally been dragged out of the shadows.

For the first time ever, humanity has photographed one of these elusive cosmic beasts, shining light on an exotic space-time realm that had long been beyond our ken.

"We have seen what we thought was unseeable," Sheperd Doeleman, of Harvard University and the Harvard-Smithsonian Center for Astrophysics, said today (April 10) during a press conference at the National Press Club in Washington, D.C.

Doeleman directs the Event Horizon Telescope (EHT) project, which captured the epic imagery. These four photos, which were unveiled today at press events around the world and in a series of papers, outline the contours of the monster black hole lurking at the heart of the elliptical galaxy M87.

The imagery is mind-blowing enough in its own right. But even more significant is the trail the new results will likely blaze, researchers said.

"There's really a new field to explore," Peter Galison, a professor of physics and the history of science at Harvard, said in an EHT talk last month at the South by Southwest (SXSW) festival in Austin, Texas. "And that's ultimately what's so exciting about this."

Galison, who co-founded Harvard's interdisciplinary Black Hole Initiative (BHI), compared the imagery's potential impact to that of the drawings made by English scientist Robert Hooke in the 1600s. These illustrations showed people what insects and plants look like through a microscope.

"It opened a world," Galison said of Hooke's work.

The project has been scrutinizing two black holes — the M87 behemoth, which harbors about 6.5 billion times the mass of Earth's sun, and our own galaxy's central black hole, known as Sagittarius A*. This latter object, while still a supermassive black hole, is a runt compared to M87's beast, containing a mere 4.3 million solar masses.

Both of these objects are tough targets because of their immense distance from Earth. Sagittarius A* lies about 26,000 light-years from us, and M87's black hole is a whopping 53.5 million light-years away.

From our perspective, Sagittarius A*'s event horizon "is so small that it's the equivalent of seeing an orange on the moon or being able to read the newspaper in Los Angeles while you're sitting in New York City," Doeleman said during the SXSW event last month.

What it all means
The EHT project has two main goals, Psaltis said: to image an event horizon for the first time ever and to help determine if Einstein's theory of general relativity needs any revisions.

Before Einstein came along, gravity was generally regarded as a mysterious force at a distance. But general relativity describes it as the warping of space-time: Massive objects such as planets, stars and black holes create a sort of sag in space-time, much as a bowling ball would if placed on a trampoline. Nearby objects follow this curve and get funneled toward the central mass.

General relativity has held up incredibly well over the century since its introduction, passing every test that scientists have thrown at it. But the EHT's observations provide another trial, in an extreme realm where predictions may not match reality. That's because astronomers can calculate the expected size and shape of an event horizon using general relativity, Psaltis explained.

If the observed silhouette matches the theory-informed simulations, "then Einstein was 100% right," Psaltis said. "If the answer is no, then we have to tweak his theory in order to make it work with experiments. This is how science goes."

And we learned today that no tweaks are needed, at least at the moment: EHT's M87 observations are consistent with general relativity, team members said.

"I have to admit, I was a little stunned that it matched so closely the predictions that we had made," EHT team member Avery Broderick, of the University of Waterloo and the Perimeter Institute for Theoretical Physics in Canada, said during today's news conference.

Such ground-truthing is vital to the scientific process, of course. Indeed, providing better information to feed into theories and simulations will likely be one of the EHT's biggest contributions, Loeb said.

"Doing physics is a dialog with nature," he said. "We test our ideas by comparing them to experiments; experimental data is crucial."

The new results should also help scientists get a better handle on black holes, he and other researchers said. For example, EHT imagery will likely shine significant light on how gas spirals down into a black hole's maw. This accretion process, which can lead to the generation of powerful jets of radiation, is poorly understood, Loeb said.

In addition, the shape of an event horizon can reveal whether a black hole is spinning, said Fiona Harrison of the California Institute of Technology, the principal investigator of NASA's black-hole-studying Nuclear Spectroscopic Telescope Array (NuSTAR) mission.

"We've inferred the spin of black holes indirectly," Harrison, who's not part of the EHT team, told Space.com. EHT imagery provides "a direct test, which is very exciting," she added.

EHT's data revealed the M87 black hole is spinning clockwise, team members said today.

The project should also show how matter is distributed around a black hole, and EHT observations could eventually teach astronomers a great deal about how supermassive black holes shape the evolution of their host galaxies over long time scales, Harrison said.

EHT's results also mesh well with those of the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has detected the space-time ripples generated by mergers involving black holes just a few dozen times more massive than the sun.

"Despite varying across a factor of billion in mass, known black holes are all consistent with a single description," Broderick said today. "Black holes big and small are analogous in important ways. What we learn from one [type] necessarily applies to the other."

A new perspective?
Then there's the broader appeal of the newly released imagery — how it speaks to those of us who aren't astrophysicists.

The contributions in this arena could be significant, EHT team members and outside scientists said. Photos can change the way we think about ourselves and our place in the universe, Marrone noted, citing the famous "Earthrise" photo taken by Apollo 8 astronaut Bill Anders in December 1968. This image, which gave the masses a glimpse of our planet as it really is — a lonely outpost of life in an infinite sea of darkness — is widely credited with helping to spur the environmental movement.

Seeing a real-life black hole — or its silhouette, anyway — "is the stuff of science fiction," Harrison said. And we've seen just the project's first few photos, she added: "They're only going to get better."
