The star Betelgeuse is so large, if you swapped it with the Sun, it would engulf the orbit of Mars and extend all the way through the asteroid belt. No need to panic, but at 700 light years, it's the closest star to the Sun that will end its life in a Supernova explosion. https://t.co/TcDqUmXrNX — PolitiTweet.org

Betelgeuse was born about 10 million years ago — long after Earth's big dinosaurs roamed the land. But the star is now near death. No need to panic, but stellar evolution models tell us that it will likely explode as a Supernova sometime within the next 100,000 years. https://t.co/h7YKSK3nO9 — PolitiTweet.org
