Astronomers reveal first image of black hole at the heart of Milky Way galaxy

In News 
  • Scientists from the Event Horizon Telescope(EHT) facility, a collaboration of over 300 researchers, revealed the first image of the black hole at the centre of the Milky Way in press conferences held around the world. 
  • This image of the black hole referred to as Sagittarius A* (SgrA*) gave further support to the idea that the compact object at the centre of our galaxy is indeed a black hole.
Sagittarius A*
  • Sagittarius A* is a supermassive black hole at the center of our galaxy i.e. the Milky Way. It is located near the border of the constellations Sagittarius and Scorpius.
  • SgrA* possesses 4 million times the mass of our sun and is located about 26,000 light-years and 5.9 trillion miles (9.5 trillion km)—from Earth.
Black Hole 
  • A black hole is an object in space that is so dense and has such strong gravity that no matter or light can escape its pull. Because no light can escape, it is black and invisible.
  • There’s a boundary at the edge of a black hole called the event horizon, which is the point of no return — any light or matter that crosses that boundary is sucked into the black hole. It would need to travel faster than the speed of light to escape, which is impossible.
  • Anything that crosses the event horizon is destined to fall to the very centre of the black hole and be squished into a single point with infinite density, called the singularity.
