Composite image from telescopes showcases ‘stellar beads on a string’

Astronomers have captured a black hole blasting one of the most intense outbursts ever recorded. 
This black hole resides in the colossal galaxy cluster SDSS J1531+3414 (or SDSS J1531). This cluster harbors hundreds of galaxies and massive reserves of hot gas and dark matter. At its heart, two of the largest galaxies in the cluster are colliding with each other. 
This mega-explosion from the black hole occurred billions of years ago.
