New Delhi: NASA's Fermi Gamma-ray Space Telescope on Tuesday spotted a record flare from black hole in distant galaxy.
The gamma rays were captured coming from a galaxy known as PKS 1441+25, a type of active galaxy called a blazar. The galaxy is black-hole-powered and more than halfway across the universe.

PKS 1441+25 is a famous blazar, a galaxy whose high-energy activity is powered by a central supermassive black hole weighing up to 70 million times the Sun's mass. What makes a blazar so bright is that one of these particle jets happens to be aimed almost straight at us.
Further explaining about the process, NASA tweeted on its official Twitter handle:
What’s a blazar? It’s a black-hole-powered galaxy and can be detected by our Fermi Telescope https://t.co/aeNLgiLr60 pic.twitter.com/x90st5ommt

According to NASA, PKS 1441+25 is one of only two such distant sources for which gamma rays with energies above 100 GeV have been observed. Its dramatic flare provides a powerful glimpse into the intensity of the EBL from near-infrared to near-ultraviolet wavelengths and suggests that galaxy surveys have identified most of the sources responsible for it.
