''It’s amazing to be able to say, here’s the black hole, the size of our
solar system, and bigger, and it has the mass of six and a half billion
suns,'' says Harvard science professor Peter L. Galison

2. The month of April had many events and highlighting stories but one of the
most major occurence is the images of Black Hole that finally came to
existence. Scientists announced last week that they had, for the first time ever,
been able to capture a photograph of a black hole, and the image
they unveiled appeared bright orange and doughnut-shaped and yet,
mesmerized every single one of us.
Black holes, by their nature, are impossible to see with the naked eye since
they are so dense that no light can escape them. Instead, any images that will
be released will be the silhouette of a black hole, an outline against all of the
super bright, hot gas that is thought to surround these weird celestial objects.
The black hole itself does not emit or radiate light, or any other electromagnetic
waves that can be detected by instruments built by human beings. But the area
just outside the boundary of the black hole — referred to as event horizon —
which has vast amounts of gas, clouds and plasma swirling violently, emit all
kinds of radiations, including even visible light.

Getting all of this data isn’t easy. In fact, the reason it’s taken so long to mount
a project of this scale is that the telescopes gather so much information — about
one petabyte, or a million gigabytes — of data each night of observing. It’s the
largest amount of recording of any other experiment in physics or astronomy,
says Psaltis.
Scientists have been using computer-simulated images of black holes for
several years to study these regions. For the first time, they have an actual
image. While they appear quite similar, scientists will now start looking closely
at the actual image to see whether it differs from the computer-simulated
images in the details, and whether these differences could be explained by
instrumentation, observation or other errors. This can provide a test for existing
theories of the universe, and lead to a better understanding of black holes and
the nature of the universe itself.
This black hole image, indeed, made history. And Einstein's theory was
proved right, which is a win for all of science and scientific history.
