Scientists capture image of black hole in galaxy called M87
April 11, 2019
NEW DELHI: The scientists have captured an image that shows the supermassive
black hole at the centre of M87 in the galaxy. The dark central shadow is corroborates Albert Einstein's 100-year old theory of relativity.
The black hole is like a cosmic trapdoor from which neither light nor matter
can escape. It is unseeable.
The breakthrough image was captured by the Event Horizon telescope (EHT), a
network of eight radio telescopes spanning locations from Antarctica to Spain
and Chile, in an effort involving more than 200 scientists.
The young female scientist behind the first-ever image of a black hole is being
hailed as an American hero. Dr Kate Bouman Bouman (29) said after the image
released, "This is just the beginning of having another window into what black
holes can tell us about our laws and physics." Bouman created the algorithm
that allowed the picture showing a fiery ring surrounding a black centre to
"At the heart of the Milky Way, there's a supermassive black hole that feeds
off a spinning disk of hot gas, sucking up anything that ventures too close
- even light. We can't see it, but its event horizon casts a shadow, and an
image of that shadow could help answer some important questions about the universe.
Scientists used to think that making such an image would require a telescope
the size of Earth - until Katie Bouman and a team of astronomers came up with
a clever alternative. Bouman explains how we can take a picture of the ultimate
dark using the Event Horizon Telescope.
A black hole is a region of space from which nothing, not even light, can escape.
They are actually not empty but consist of a huge amounts of compressed matter
and so has huge gravitational pull. Beyond the black hole is the event horizon,
the "point of no return."
The black hole found was in a galaxy called M87. It is larger than the size
of our entire solar system. "It has a mass 6.5 billion times that of the Sun.
And it is one of the heaviest black holes that we think exists. It is an absolute
monster, the heavyweight champion of black holes in the Universe," BBC quoted
There is a "ring of fire" around the dark hole. The halo is caused by superheated
gas falling into the hole. "The light is brighter than all the billions of other
stars in the galaxy combined - which is why it can be seen at such distance
from Earth," he said.
Astronomers always thought the M87 galaxy has a supermassive black hole because
of images emitted.
Black holes raise fundamental issues of time, space and life.
