Our galaxy has a supermassive black hole at its centre as well, which has also ejected material at one time over the past few million years. While even light can not escape the pull of one of these gravity wells, blacks holes do, very occasionally, "burp" back out chunks of half-consumed gas.
The Hubble telescope then picked up clouds of blue-green gas emerging from the black hole from a previous burp. Investigators said that they are very fortunate that they observed this galaxy in a moment where they were able to see both these events very clearly.
Details of Comerford and her team's study were published in the The Astrophysical Journal and presented January 11 at the meeting of the American Astronomical Society in Washington, D.C.More news: Poised For a Move? BCE Inc (BCE) See Shares Move
"We are seeing this object feast, burp and nap, and then feast and burp once again, which theory had predicted", said lead author of the study Julie Comerford of the University of Colorado at Boulder's Department of Astrophysical and Space Science in a statement.
For comparison, one light-year is approximately 6 trillion miles.
The Hubble and Chandra space telescopes detected the burp 800million light-years away. The Apache Point facility is owned by the Astrophysical Research Consortium, a group of 10 USA research institutions that includes CU Boulder.
Investigating J1354, Chandra detected a supermassive black hole, millions or billions of times more massive than the Sun, at the centre of the galaxy, embedded in a thick cloud of gas and dust. Comerford said that these events of bubbles appear after a black hole feeding process.More news: Karni Sena members held while protesting outside CBFC office
So why did the black hole have two separate meals?
Ms Comerford stated: "There's a stream of stars and gas connecting these two galaxies".
This may not even be all that rare of an occurrence, if the supermassive black hole at the center of the galaxy named "SDSS J1354+1327" can be taken as a typical example of these hungry monsters. "This new burp is actually moving like a shock wave - it's coming out very fast, and so it's kind of like a sonic boom of a burp, whereas the gas to the south shows us an older burp that happens 100,000 years earlier before that newer burp". In 2010 another research team discovered a Milky Way belch using observations from the orbiting Fermi Gamma-ray Observatory to look at the galaxy edge on. She added that if our solar system was close to the black hole than it would be hazardous for us.More news: Wesley Mathews indicted for capital murder
