Over the past 5 months, Betelgeuse has dimmed up to 36% and scientists are suggesting that the star might have entered its pre-supernova phase.
Just like humans, stars age and dies eventually. During its final stage, the stars explode and this blast is referred to as the Supernova.
I am very proud to be leading this worldwide effort to understand what is happening to dear #Betelgeuse ❤️. The first release of our campaign is a stunning before/after image of the star's surface. Thanks to all my team members and to @ESO ! More info : https://t.co/u6LP26IyWL pic.twitter.com/FnFRBRuvk0— Miguel Montargès (@Astro_MiguelM) February 14, 2020
It is believed that the Betelgeuse's supernova might be visible from earth and will be the brightest stellar event ever recorded in history. The scientists are still studying the drastic changes in the star to determine its life span.
But since Betelgeuse is located 700 light-years away, everything we're seeing now has happened 700 years ago.
