06.09.2009 – Red giant star Betelgeuse mysteriously shrinking

Quite interesting though it’ll likely be years before scientists know wether this is simply another of the star’s cycles or if it’s approaching a supernova. If this ends up being Betelgeuse going supernova it’ll certainly be a scientific boon as far as getting a better understanding and confirmation on star life cycles.

Perhaps more interesting, at least to the public, is such a supernova will likely be bright enough to be seen during  daylight hours on Earth. Certainly whenever this happens the night sky will be much different looking.
