Read more Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner rather than later. That's because it's a red supergiant on the verge of becoming a supernova and there hasn't been one explode this close in recorded human history. It's been changing its brightness and showing strange surface behavior, which is why astronomers track its activity closely. Are these changes due to its aging process? Do they mean it's about to blow up? Probably not. Show less

At cold temperatures, hydrogen cyanide forms crystals. And, according to computer models reported in ACS Central Science, some of the facets on these crystals are highly reactive, enabling chemical reactions that are otherwise not possible at low temperatures. The researchers say these reactions could have started a cascade that gave rise to several building blocks of life. Show less
