Black hole rips apart doomed star in 'rare' event

Black hole rips apart doomed star in 'rare' event

For the first time, researchers have observed a star collapsing under cosmic upheaval (cosmic cataclysm) by a black hole weighing six million times the Sun.

Scientists have grabbed a shocking image of a massive black hole brutally tearing up a star, depicting a phenomenal and wild cosmic event from its beginning to its end for the first time.

'We were only looking for pairs of black holes at the time, and yet, through our selection technique, we stumbled upon this fantastic system, ' mentioned Ryan Pfeifle of George Mason College in Fairfax, Virginia, the primary writer of a brand new paper in The Astrophysical Journal describing these outcomes. Scientists used an global network of 20 robotic telescopes called ASAS-SN (All-Sky Automated Survey for Supernovae) to detect the tidal disruption event back in January, before turning to TESS, which caught the beginning of the cosmic showdown. It becomes trapped in the black hole's gravity and spirals in toward the event horizon. The other light from the disk deflects back due to the gravitational field of the black hole. TESS first recorded this tidal dissolution on 21 January. It took place about 375 million light years away in a galaxy called 2MASX J07001137-6602251. Luckily, the break-up of the star was quite bright, and it happened in the satellite's continuous viewing zone above the south pole.

NASA reported that when Holoien came to know of the incident from the network's equipment located in South Africa, he immediately hired two robotic telescopes in Las Campanas, Chile to find the actual location of the event in the universe.

TESS screens enormous swaths of the sky, called segments, for 27 days one after another. However, ASAS-SN didn't see the event until a week after TESS. "Additionally they show that ASASSN-19bt's rise in brightness was very smooth, which helps to tell that the event was a tidal disruption, not another kind of outburst, like from the center of a galaxy or a supernova". The TESS observational campaign is still ongoing, so there's still time to spot some more tidal disruption events.
