'''AT2019qiz''' is a [[tidal disruption event]] (TDE) that occurred at a distance of 215 millions [[light year]]s (65 [[megaparsec]]), from Earth.<ref name="outflow">{{Cite journal |last1=Nicholl |first1=M. |last2=Wevers |first2=T. |last3=Oates |first3=S.

It involves a star with a sun-like mass and a black hole with a mass of around 10<sup>6</sup> [[solar mass|solar masses]]. The TDE appears very young and increasing in brightness. The encounter tore away half of the mass of the star and threw debris at a speed of 10,000 km/s, comparable to that observed in [[supernova explosion]]s.<ref>{{Cite web |last= |title=Death by Spaghettification: ESO Telescopes Record Last Moments of Star Devoured by a Black Hole |url=https://www.eso.org/public/news/eso2018/ |access-date=2020-10-13 |website=www.eso.org |publisher=[[European Southern Observatory]]}}</ref><ref name="outflow"/>
