Everybody knows that black holes are essentially ‘evil’ – they devour any cosmic objects that gets too close to them. Not even light can escape a gravitational force of a black hole. Although scientists are still struggling to fully understand how a black hole works, one thing’s for sure: such mysterious cosmic objects also have a very useful role in the mere existence of the galaxies.
Astronomers believe that a supermassive black hole lies at the center of most galaxies. At least that is the case for our Milky Way galaxy. The huge gravitational pull of a supermassive black hole shapes the entire galaxy and makes it spin. But that’s not the only way black holes can be useful.
NASA made a fabulous discovery
NASA made a jaw-dropping discovery by using Chandra X-ray Observatory and other telescopes. The researchers involved discovered for the first time a black hole that was the culprit for star formation in multiple galaxies that are millions of light-years away from each other. The newfound black hole is located 9.9 billion light-years away from us, and it has created the fuel for stars from at least four neighboring galaxies to form.
Roberto Gilli, who is the lead author of the study and a researcher from the National Institute of Astrophysics (INAF) from Bologna, stated:
This is the first time we’ve seen a single black hole boost star birth in more than one galaxy at a time,
It’s amazing to think one galaxy’s black hole can have a say in what happens in other galaxies millions of trillions of miles away.
How it was possible
Stars form when hydrogen gas gets compressed due to gravity. Supermassive black holes that are active will shoot powerful outbursts of material into deep space, like radio-wave emissions and others. This is the fuel that allows stars to form.
As incredible as it sounds, this is another proof that there is creation in the Universe even in a very destructive phenomenon like a black hole. And what could be more fascinating than that?
The findings have been published on September 18 in the journal Astronomy and Astrophysics.
