Massive collision of black holes took place in ancient space. One had 50 million times mass of Sun

With the help of the James Webb Space Telescope, scientists have spotted the most ancient collision of a black hole,likely to havetaken placewhen the universe was only 740 million years old.

For the first time, astronomers have spotted such a mergerwhichalso appears to be the first one to have taken place in thehistory of the universe. It occurred in the galaxy system called ZS7.

Black holes are massive cosmic items spread across our universeandtheir gravitational fields are strong enough to stop even light from escaping their event horizons.

When two black holes merge, they sound dreadfulandthe process takes place slowly as theycoalesceinto a single object.

One black hole was 50 million times the mass of the Sun:Scientists

In an ESA(European Space Agency) release,thestudy’slead author and an astronomer at theUniversity of CambridgeHannahUblersaid,“Our findings suggest that merging is an important route through which black holes can rapidly grow, even at cosmic dawn."

“Together with other Webb findings of active, massive black holes in the distant Universe, our results also show that massive black holes have been shaping the evolution of galaxies from the very beginning,"she said.

The vision of the James Webb Telescope was so sharp that the team spatially separated the two black holeswhichhelped them understand some of their physical characteristics.

It was foundthat one of the Black Holes was nearly 50 million timesthe mass of the Sunandthe other was hiddenin a dense cloud of gas.

The Laser Interferometer Space Antenna (LISA),which isaspace-based gravitational wave observatory, was formally adopted by the ESA in Januarywhichpaved the way for the eventual operation and launch of the spacecraft.

In the press release,LISA’sleadproject scientist at the European Space Agency Nora Luetzgendorf said, “Webb’s results are telling us that lighter systems detectable by LISA should be far more frequent than previously assumed."

“It will most likely make us adjust our models for LISA rates in this mass range.Thisis just the tip of the iceberg,"she added.
