First glimpse of black hole on the anvil

Black holes are extraordinarily dense entities formed when very massive stars collapse at the end of their life cycle

Black holes are extraordinarily dense entities formed when very massive stars collapse at the end of their life cycle

Astronomers say a major announcement is on the way based on findings from the global Event Horizon Telescope project, which experts believe could be the first-ever photographs to show the surroundings of a black hole.

They are extraordinarily dense entities and have gravitational fields so intense no matter can escape being sucked in, including stars, planets, gas, dust and light.

This handout released by Paris Observatory - PSL on February 19, 1919, shows an image taken with the low-fFrequency array radio telescope of a galaxy and its supermassive black hole ejecting jets of material, stacked on an optical image of the sky.

While scientists involved in the research declined to disclose the findings ahead of the formal announcement, they are clear about their goals.

"The black hole shadow was first studied and computed more than 40 years ago by Jim Bardeen in the USA and by Jean-Pierre Luminet in France". The scientists also want to know whether Albert Einstein's theory of general relativity works in a black hole and whether collapsed stars known as pulsars surround the Milky Way's black hole. That theory, put forward in 1915, was meant to explain the laws of gravity and their relation to other natural forces.

Past year was when Halsey first dropped the hint that she'd be teaming up with BTS , revealing herself as a big fan of the group. Following the release of the album, BTS will embark on a Love Yourself: Speak Yourself world tour.

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. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Streaming away from M87 at almost the speed of light is a large jet of subatomic particles. Supermassive black holes are the largest kind, devouring matter and radiation and perhaps merging with other black holes.

"Nevertheless, it will be very nice and gratifying to see the black hole shadows directly". The strong gravity - the "event horizon" - of black holes creates a dark shadow with a distinct shape where no light can be seen.

The scientists behind the EHT project said they would aim to capture a razor-sharp image, but warned it wouldn't be easy.

"The shape of the [black hole's] shadow will be nearly a flawless circle in Einstein's theory", Dr Psaltis said.

"If we find it to be different than what the theory predicts, then we go back to square one and we say, "Clearly, something is not exactly right".
