A space telescope has captured the spectacular moment a "super volcano" exploded from a giant black hole in a galaxy about 50 million light years away from earth.
The photograph, taken by NASA's Chandra X-Ray Observatory and the NSF's Very Large Array, showed gas and radio emissions being blasted throughout the Messier 87 (M87) galaxy, Wired reports.
Scientists said the black hole was powering the super-volcano and that jets of energetic particles were preventing the formation of hundreds of millions of new stars.
New stars would normally form in the galaxy when the super-heated gas cooled.
Instead, the eruption interrupted this process, blasting away the cooled gas with such force that a shockwave travelled throughout the galaxy.
"Our results show in great detail that super massive black holes have a surprisingly good control over the evolution of the galaxies in which they live," scientist Norbert Werner was quoted as saying.
Researchers said the galactic eruption was similar to the recent Iceland volcano eruption, which shot plumes of ash and smoke into the atmosphere and disrupted flights across the globe.
"This analogy shows that even though astronomical phenomena can occur in exotic settings and over vast scales, the physics can be very similar to events on Earth," expert Aurora Simionescu said.

this could be the day
hold my hand
lie beside me
i just need to say
