NASA mapped black holes in the universe

Scientists from the US Aerospace Agency (NASA) have used SWIFT satellites to capture space in many angles and map black holes in distances of less than 400 million light-years.

This map includes more than 200 supermassive black holes called AGN (Active Galactic Nuclei - the most active galactic nuclei), compared to all previous studies.

AGNs have a mass equivalent to millions of billions of solar masses but concentrated in a space the size of the solar system.

The concept of ' activity ' in the names of these black holes is shown by the fact that they attract a large amount of nearby gas and stars and emit enormous energy.

SWIFT satellite was launched by NASA in 2004, with the initial task of studying gamma rays in the universe but can also be used to observe high-energy X-rays as in the case of studying black holes this time. .

NASA's 9-month research results show that almost all galaxies in our universe have a black hole but some are ' sleeping ' while others act like AGNs.
