Astronomers Think They Have a Warning Sign for When Massive Stars are About to Explode as Supernovae
Показать описание
The red supergiant stars are a potential source of explosions. They appear swollen and red because they are fusing heavier atoms in a last-ditch attempt to prevent collapse. But in the end, gravity will triumph, and the red supergiant's core will collapse, resulting in a supernova. We've always known it was inevitable, but the timing wasn't known.
Betelgeuse, a brilliant red star in Orion, is the most well-known example of a red supergiant. Roughly 550 light-years distant, it has the mass of 18 Suns and a diameter of about 5.5 arcseconds. Eventually, it will explode, making it brighter than the Moon, and it will be the nearest red supergiant to Earth. This, of course, has led to wild speculation over the star. Does it have the potential to go off within our lifetime? Is the supernova light already there, and we're simply waiting for it to arrive? No one in the astronomical community is sure, but the best guess is that it's not.
Recent research, however, may allow us to know months in advance that Betelgeuse will explode.
