    NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the star should not have self-destructed so early in its life. "This might mean that we are fundamentally wrong about the evolution of massive stars, and that theories need revising," says Avishay Gal-Yam of the Weizmann Institute of Science, Rehovot, Israel.

    Very inetersting. Now we just need to watch out for our Sun changing into Red Giant if fundementals of our star theories are wrong


    Only the mind can think twice simultaneously about a subject, but only one thing can inexorably come out of it. A choice.

    the stars collaps could have being caused by a variable in the stars mass???

    Stars goes through short and long cycles caused by oscillations inside them. Could it be possible that a standing wave of some kind could build up and cause a star to start continuously heating up and maybe cause a super-nova?

    We know that a star's magnetic field causes the corona of a star like ours to heat up to a million degrees centigrade. What would happen if instead, something caused it to heat up the star itself till it went supernova?

    A star might go super-nova if a large enough planet literally fell into it, particularly if it was a gas giant a few times the mass of Jupiter.

    Apart from that, stars have a set mass which they very slowly lose and at certain times of their life, a certain composition. They are normally fairly predictable.
