Scientists continue to study supermassive black holes. As it turned out, one of these objects was able to absorb a star, the mass of which is three times the mass of the Sun.

Here's What We Know

The incident occurred at a distance of 290 million light years from our planet in the galaxy PGC 043234. Scientists first saw it in 2014. The event was named ASASSN-14li. The X-ray space telescopes XMM-Newton and Chandra were brought in to observe it again.

Tidal disruption happens when a star passes too close in a supermassive black hole. Under the influence of the gravitational field, the star's debris heats up, triggering a flash seen in the ultraviolet, X-ray and optical bands.

Studying the ejected remnants of the star, scientists determined that it was three times more massive than the Sun (~1,989 × 1030 kg). Interestingly, six years ago, a study on ASASSN-4li said the mass of the collapsed star was only 60 per cent of the solar mass.
