A supermassive black hole, supposed to be located in Abell 2261 galaxy cluster, is seemingly missing, leaving astronomers perplexed.
- The missing black hole is estimated to weigh up to 100 billion times the mass of the Sun.
- The Abell 2261 galaxy cluster is about 2.7 billion light-years away from our planet.
- Despite searching with NASA’s Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole is anywhere to be found.
- Centre of the galaxy: Every large galaxy in the universe has a supermassive black hole at its centre, whose mass is millions or billions of times that of the Sun.
- Sagittarius A: The black hole at the centre of our galaxy– the Milky Way– is called Sagittarius A* which is 26,000 light-years away from Earth.
- Light Year: One light-year is the distance that a beam of light travels in one Earth year, which is 9 trillion km.
