Supermassive black holes are the largest type and are found at the centres of almost all big galaxies.
"'Right now, our galaxy's supermassive black hole is firmly in the nap phase of the feast-burp-nap cycle, but it's just waiting for its next meal to come along", Comerford added.
While black hole burps have been observed before, this was a lucky chance to confirm multiple belches.
So, why did this black hole get seconds after its dinner?
A burp consists of high-energy particles that are kicked back out of the centre of a black hole.
The research was presented yesterday at the American Astronomical Society's annual meeting in Washington, DC.
They tend to occur after events where the black hole has engulfed a large amount of matter, which some scientists call a "meal".
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. At one point the pair collided and the material was eaten by the supermassive black hole.
In the same way as normal black holes, they are regions of space-time with gravitational effects so strong that even light can not escape from inside of them.
This energy is released in quasars that are seen visible light and X-ray wavelengths.
Observing these burps could show how when a hungry hole will awaken and begin wolfing down anything unlucky enough to be within sucking distance of its gravitational pull.
Hubble was able to show them that a cloud of blue-green gas extending away from the black hole represented the aftermath of an earlier burp.
As the researchers analysed the first burp, they saw another burst of radiation from the black hole, this time north of the super dense object.
The reason the galaxy burped up material twice is due to a companion galaxy that interacted with J1354.
'This collision produced a stream of stars and gas that links J1354 and the other galaxy.
'If our solar system was very close to the black hole, though, we'd be fried'.
'The separate outbursts from the black hole are caused by different clumps from this stream being consumed by the supermassive black holes'.
Dr Comerford said that the black hole was going through a cycle of feasting, belching and napping, before starting again.
