Using two glasses, astronomers have found a black hole at the centre of a galaxy 800 million swift years away that has spewed material into space not again, but twice.
Most galaxies have a supermassive black hole at their naves, which consumes anything that gets too close. And while we gravitate to think of nothing escaping a black hole’s fierce grasp, when they swamp material, some of it is ejected into space in the form of high-energy bits.
In order to see the two events, astronomers used data from ground-based digests as well as the Hubble Space Telescope and the Chandra X-Ray Observatory.
Optical materials from Hubble and the other telescopes found that the black joint — which is millions or perhaps billions of times more massive than our sun — at the hub of the galaxy designated SDSS J1354+1327 had ejected material twice, 100,000 years aside from.
«We are seeing this object feast, burp and nap, and then feast and burp at the same time again, which theory had predicted,» said lead author of the haunt Julie Comerford of the University of Colorado at Boulder’s Department of Astrophysical and Organize Science in a statement.
«Fortunately, we happened to observe this galaxy at a all at once when we could clearly see evidence for both events.»
The reason the galaxy burped up stuff twice is due to a companion galaxy that interacted with J1354. At one object the pair collided and the material was eaten by the supermassive black hole.
Our galaxy has a supermassive baneful hole at its centre as well, which has also ejected material at one speedily over the past few million years.
