Scientists have recently revealed the first ever
image of a black hole. The black hole is located at the centre of a distant
galaxy called Messier 87 (M87) located in Virgo A constellation. It is
supermassive-6.5 billion times the Solar mass.
The image of the black hole was taken by the Event
Horizon telescope (ETH). The ETH is a project comprised of eight different
telescopes at different observatories around the world. It has been operating
in synchronicity to image the black holes in the centre of M87 galaxy and Sagittarius
A* black hole located at the centre of the Milky Way galaxy.
A black hole is a region of space from which
nothing, not even light, can escape. These black holes consist a huge amount of
matter packed densely into a small area, giving it an immense gravitational
pull. Black holes are thought to be formed when very massive stars collapse at
the end of their life cycle.
The black hole itself cannot be seen as light
cannot pass through it. It possess an event horizon- a boundary designating the
point of no return. Any object including light that falls within its event
horizon is sucked into the black hole. However, if something that orbits the
black hole outside the event horizon shines as it usually does, the black hole
can be seen in shadow against this shine.
