Scientists consider that the black hole exploded the gas twice because it might have two meals at the same time. The hole's gaping maw is sucking up massive amounts of material, burping some of it out in a huge shockwave-like event, and then resting for a brief period before resuming its feast. Comerford presented the team's findings in a January 11 press briefing at the 231st meeting of the American Astronomical Society held January 8-12 in Washington D.C. The Galaxy is known as J1354, which is around 900 million light years away from Earth. These supermassive black holes are million times heavier than the Sun and scientists consider that these holes are in the centre of every galaxy. This simply means that one of them was ejected to one side of the black hole, and the other one, which is actually bigger and more compact, got ejected 100 thousand year later, in the other direction. For comparison, one light-year is roughly six trillion miles. Finally, scientists managed to use imagery from the Hubble and Chandra space telescopes to discover empirical proof of such a cycle taking place. The Apache Point facility is owned by the Astrophysical Research Consortium, a group of 10 USA research institutions that includes CU Boulder.
A space "burp" consists of high-energy particles being launched back into space from the depths of a black hole.
The explanation for these gas-feeding events lies in a companion galaxy, which had previously collided with J1354.
It is quite common to see a black hole doing one burp, but extremely unusual to see it let rip twice in a row.

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.
Comerford said the team observed a remnant emission south of the center of the galaxy that indicated there was a black hole feasting event roughly a million years ago.
"This galaxy really caught us off guard", said study author and University of Colorado Boulder doctoral student Rebecca Nevin. "We were able to show that the gas from the north part of the galaxy was consistent with an advancing edge of a shock wave, and the gas from the south was consistent with an older quasar outflow". Researchers said that they could see this object having meal, nap and belch and repeating these activities.
Julie also said that this galactic burp is nothing to worry about. Astronomers saw gas jets dubbed "Fermi bubbles" that shine in the gamma-ray and X-ray portions of the electromagnetic spectrum. This happens especially if the main feed of the black hole is gas.
