Billions light years from Earth, a supermassive black hole in a galaxy feeds on gas clouds. The accidental observation caught a sight from ALMA telescope located in Chile's Atacama desert. The observatory that released a report from a team of international astronomers describing three clouds that moved toward the black hole. It recorded a speed of 1.3 km per hour, The Guardian reported.

The rare phenomenon was the first time ever to be recorded. Astronomers have been mentioning how easy supermassive black hole feeds itself. Supermassive black holes in galaxies are surrounded by sphere of gas, in which temperature is high. Michael McDonald from MIT explained in brief how the gas accelerated towards its meal.  However, after noticing it eating clouds of cold gas, scientists believe that the process might be chaotic.

There were clouds of cold gas in large sizes that moved towards the supermassive black hole. According to the team, this is the new evidence that backs the research on how black holes eat clouds of gas. This cold gas is the fuel for the black hole in short term.

The new observation confirmed that supermassive black hole in galaxy has two ways of eating. So far, scientific theories mathematically found that the black hole feeds on 'hot ionized gas from halo' but now the evidence unveiled that it also swallows 'messy and asymmetrical' clouds of cold gas when it travels nearby, CBC Canada reported.

Originally, scientists observed there are varieties of diet that supermassive black hole feed on but the cold system is the first ever to be seen. The ALMA observatory has succeeded in capturing the process from the very beginning that it travels toward the abyss. The telescope uses system that enables it to see radio waves. Astronomers are now looking for further information on the similar precipitation process in the other galaxies.
