Black Hole Image: How Indian Scientists Contributed in This Feat Will Wow You

The Quint  

Latest images have shown a ring-like structure with a dark central region — the shadow of the Messier 87 black hole. What we see in the latest images are the signatures of particles outside the event horizon and not the inner core of the black hole. The whole thing can be seen as a bright disc of glowing gas in the image where the black hole is expected to create dark regions like making a shadow. The boundary where the shadow begins marks the “event horizon”, the region around the centre of the black hole from where matter and energy cannot escape the black hole’s gravity or fondly called as ‘point of no return’!

Rapidly growing black hole found, could provide clues on how massive galaxies first evolved

The Hindu  

Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe, according to a new study. Using observations taken with the Atacama Large Millimeter Array, a radio observatory sited in Chile, the team have determined that the galaxy, named COS-87259, containing this new supermassive black hole is very extreme, forming …

Shadow cast by a supermassive black hole supports Albert Einstein's theory of general relativity

Daily Mail  

Albert Einstein's theory of general relativity – the idea that gravity is matter warping spacetime- has faced more than 100 years of scrutiny, but a new discovery may help support the physicist's hypothesis. The team found the intense gravity of the black hole bent spacetime, thereby 'acting as a magnifying glass and causing the black hole shadow to appear larger'. …
