Event Horizon Telescope project reveals First-ever photo of Black Hole

Marking a milestone in astrophysics - the first-ever photo of a black hole was released from a research conducted by the Event Horizon Telescope (EHT) project.

Event Horizon Telescope project reveals First-ever photo of Black Hole

Details:

  • The photo of the black hole was taken using a global network of telescopes to gain insight into celestial objects with gravitational fields so strong no matter or light can escape.
  • The research was conducted by the Event Horizon Telescope (EHT) project, an international collaboration begun in 2012 to try to directly observe the immediate environment of a black hole using a global network of Earth-based telescopes.
  • The announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo.

About the image:

  • The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster.
  • This black hole resides about 54 million light-years from Earth.

What are Black Holes?

  • Black holes, phenomenally dense celestial entities, are extraordinarily difficult to observe despite their great mass.
  • A black hole's event horizon is the point of no return beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation - gets swallowed into oblivion.
  • The fact that black holes do not allow light to escape makes viewing them difficult.
  • The scientists look for a ring of light - disrupted matter and radiation circling at tremendous speed at the edge of the event horizon - around a region of darkness representing the actual black hole.
  • This is known as the black hole's shadow or silhouette.

Interesting to know:

  • The project's researchers obtained the first data in April 2017 using telescopes in the US states of Arizona and Hawaii as well as in Mexico, Chile, Spain and Antarctica.
  • Since then, telescopes in France and Greenland have been added to the global network.
  • The global network of telescopes has essentially created a planet-sized observational dish.
