giant dying star explodes as scientists watch in real time the death of a star is one of the most dramatic and violent events in space and astronomers had an unprecedented front row seat to the explosive end of a stellar giant groundbased telescopes provided the first realtime look at the death throws of a red super giant star while these aren't the brightest or most massive stars they are the largest in terms of volume please let us know what you think of our videos also if you have not subscribed to our Chann Channel secrets of space Please

witnessed this event they believed that red super Giants were relatively quiet before exploding into a supernova or collapsing into a dense neutron star instead scientists watched the star self-destruct in dramatic fashion before collapsing in a type 2 Supernova this star death is the rapid collapse and violent explosion of a massive start after it has burned through the hydrogen helium and other elements in its core All That Remains is the star's iron but iron can't fuse so the star will run out of energy when that happens the iron collapses and causes the Supernova this is a
breakthrough in her understanding of what massive stars do moments before they die direct detection of pre Supernova activity in a red super giant star has never been observed before in an ordinary type 2 Supernova for the first time scientists watched a red super giant star [Music] explode astronomers were first alerted to the Stars unusual activity 130 days before it went supernova bright radiation was detected in the summer of 2020 by the University of Hawaii Institute for astronomy pan Stars telescope on Maui's holak BL then in the fall of that year the researchers witnessed a supernova
in the same spot the star was observed using WM kek observatories low resolution imaging spectrometer on Mona Hawaii and named the Supernova 20120 dlf their observations revealed that there was material around the star when it exploded the bright gas that the star violently kicked away from itself over the summer it's like watching a taking time bomb scientists have never confirmed such violent activity in a dying red super giant star where we see it produce such a luminous emission then collapse and combust until now some of these massive stars likely experience consequential internal changes that caus
the tumultuous release of gas before they die the finding has shown the work was conducted they had remotely access to the kek observatory's telescopes in Hawaii which was instrumental in providing direct evidence of a massive start transitioning into a supernova explosion I am most excited by all of the new unknowns that have been unlocked by this discovery detecting more events like SN 2020 tlf will dramatically impact how we Define the final months of Stellar Evolution uniting observers and theorists in the quest to solve the mystery on how massive stars spend the final moments of their
lives let us know in the comments below what you think of dying star explosion thank you for watching
