Supergiant star Betelgeuse, the ninth brightest star in terms of apparent magnitude and the brightest stars one can see from earth despite being 640 light years away, is going to transform from a red supergiant into a supernova some day. Astronomers can not pinpoint the day, year, century, the millennia or even if it will be a million years. Nonetheless, the star will implode due to gravitational collapse from the loss of mass. Discovery News’ Ian O’Neill gives the real story on Betelgeuse.
