What is a black hole?

In fact, black holes exhibit such strong gravitational forces that no matter, particles or electromagnetic radiation such as light can escape it.

"This (photo) is a pioneering find in the study of black hole astro-physics", Asada said, explaining that the EHT observations use a technique called very-long-baseline interferometry (VLBI), which synchronizes telescope facilities around the world and exploits the rotation of the planet to form one huge, Earth-size telescope observing at a wavelength of 1.3mm. The announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo.

Albert Einstein's theory of relativity is confirmed.

"We have achieved something presumed to be impossible just a generation ago", said EHT project director Sheperd S. Doeleman.

Getting an image of a black hole is one of those things that seem impossibly challenging, but with the efforts of astronomers all around the world, humanity is finally getting a direct glimpse of this cosmic object.

On April 17 they'll host: "Bringing Black Holes into Focus with the Event Horizon Telescope". Though much smaller than M87's black hole, it still boasts an impressive mass of about 4 million times that of our sun.

"Just a couple of years later, Karl Schwarzschild - he was a German astronomer who was stationed on the Russian front in World War One and was charged with calculating artillery trajectories - somehow gets ahold of Einstein's manuscript and realises something incredible".

The project cost $50 million to $60 million, with $28 million of that coming from the National Science Foundation. "We're seeing the unseeable".

Taking a photo of a black hole's shadow is the closest we can come to photographing the black hole itself.


The team looked at two supermassive black holes, the M87 and the one at the center of our own Milky Way galaxy.

The first-ever images of a black hole are set to be released on Wednesday afternoon by the Event Horizon Telescope (EHT). The image of the black hole looks like a blurry ring of fire shrouded in darkness. Einstein a century ago even predicted the symmetrical shape that scientists just found, she said. With M87, it deviated from flawless circularity by less than 10 percent.

Katie's method of processing the raw data was instrumental in creating the first ever black hole image.

The black hole will bear a Hawaiian name "pōwehi" meaning this embellished dark source of unending creation.

Harvard & Smithsonian, said in a statement.

The discovery was quite possibly the worst kept secret in the scientific world leading up to the global announcement. Now scientists think black holes lurk in the hearts of other galaxies.

Streaming away from M87 at almost the speed of light is a enormous jet of subatomic particles, though that was not captured in the photo.

The photo shows a bright ring of superheated gasses falling into the perfectly circular hole, which is the event horizon beyond which not even light can escape. In September 2015, he designed a Doodle following a report of liquid water flowing on Mars, and in February 2017, his Doodle celebrated NASA 's discovery of seven Earth-size exoplanets orbiting a star about 235 trillion miles (378 trillion kilometers) away.
