First real image captured of black hole by event horizon telescope at messier 87 galaxy
Let us know this galaxy

| M87 Galaxy supper massive black hole image invisible light
When Albert Einstein studies general theory of relativity and understanding space and time how it works,this theory predicted as a region of space from which nothing can escape ,even light.reason why we can't see direct by own eyes.
What is black holes ?
When a massive star dead or collapse by the end of its life cycle,it will be consumed by own gravity.as result formed heavy stellar mass which is curvature of space time,it can increase by absorbing mass by its surrounding.we can't see by normal telescope because black hole cannot emit light particles. Approximately every black holes exist centre of the Galaxy,even our Milky Way exist supermassive black holes.Nearest black hole far away from the planet Earth 3000 lights year.
Messier 87 or m87 galaxy?
Messier 87 galaxy far away 53 billion light years
In 1781, french astronomer Charles messier who discovered the m87 galaxy.m87 is about 53 millions light years far away from the planet Earth
Which diameter expanded 120 light year.it is very small galaxy if compared to our Milkyway galaxy
Which is 150-200(kly )but density of star so massive than the Milkyway. it is also known as virgo a situated in virgo constellation.
Spiral galaxy as Milkyway
Irregular galaxy
Elliptical galaxy as M87
What is event horizon?
Fig: illustration event horizon of black hole
Event horizon refers to that zone where all gas ,cloud stellar mass revolving round the centre of the black hole as results friction produces light, energy,jet beam near the black hole,all stellar mass trapped by massive gravity of black hole.
We cannot see black holes by our eyes we could only see event horizon at visible light.
What is event horizon telescope?how it's works
Image:working principle of event horizon telescope
The Event Horizon Telescope April 2017 observing campaign comprised eight telescopes in six geographic locations. Solid baselines indicate telescope pairs that could see M87's black hole simultaneously; dashed lines indicate telescope pairs used to observe a different, calibration source
