A big black hole has been captured pulling in and ripping apart a star for the first time. Earlier this year earthlings were treated to their first-ever picture of a black hole, and NASA's most recent GIF-style animation of one of the lightless beasts was straight out of Interstellar.
'We were only looking for pairs of black holes at the time, and yet, through our selection technique, we stumbled upon this unbelievable 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. This cosmic level collision is labelled as a tidal disruption event or TDE, which is when a black hole begins the process of tearing the gas from the star before it eventually forms into an accretion disk.
The US space agency's orbiting Transiting Exoplanet Survey Satellite, better known as TESS, revealed the detailed timeline of a star 375 million light-years away warping and spiralling into the unrelenting gravitational pull of a supermassive black hole, researchers said on Thursday. Now, we're being treated to our first glimpse of what NASA refers to as a "star-shredding black hole", and even the below simulated visualization of the event is hauntingly handsome. This was the first such event observed by TESS, but scientists hope it won't be the last. As light circles the black hole two, three or more times, it forms a photon ring. The All-Sky Automated Survey for Supernovae (ASAS-SN) is a network of robotic telescopes created to detect events like ASASSN-19bt. NASA's TESS space satellite was originally launched back in April in 2018 to search for alien planets, and so far it has discovered 24 exoplanets and 993 possible candidate worlds.
Firstly, rest-in-peace star ASASSN-19bt. ASAS-SN was able to do so because its array of 20 robotic telescopes based in both the northern and southern hemispheres is capable of surveying the entire sky approximately once every day. The smooth increase in brightness detected by TESS also confirms this was a tidal disruption event and not another high-energy outbursts like a supernova.
