The much awaited ‘reality’ is released by scientists…’Black Hole’

a historic day in science
first close-up image of black hole

  • The image of a dark core with a flame-orange halo of gas and plasma shows a supermassive black hole 50 million light years away…
  • YES…It happened. Scientists using the Event Horizon Telescope (not through computer-generated imagery) have captured the first real image of a black hole. The snapshot of the supermassive black hole in the Messier 87 galaxy (about 55 million light years away) shows the “shadow” created as the event horizon bends and sucks in light. It also confirms that the black hole is truly huge, with a mass 6.5 billion times that of the Sun.
  • Taking this picture was tricky — it required worldwide collaboration that wasn’t possible until recently.
  • The image required connecting eight existing high-altitude telescopes, including ones Chile and Antarctica, to reach an angular resolution high enough to capture such a relatively compact object (the event horizon is “just” 24.9 billion miles across).
  • This technique, also involved synchronizing atomic clocks and even taking advantage of the rotation of the Earth. Supercomputers at the Max Planck Institute and MIT’s Haystack Observatory had to combine “petabytes” of raw data from the telescopes.

Astronomers discover 83 supermassive black holes as big as the Sun in the early universe

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,”

said Michael Strauss, a professor at Princeton University in the US.

Astronomers have discovered 83 quasars (a massive and extremely remote celestial object) powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

Supermassive black holes, found at the centres of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar”.
