Science: Astronomers Awaiting 1a Supernova

Aryabhata writes to tell us BBC News is reporting that astronomers
have sighted a star on the brink of a "1a" supernova. This opportunity
presents the first chance astronomers have ever had to view a supernova
of this magnitude up close. From the article:
"They are so rare that the last one known in our galaxy was seen in
1572 by the great Danish astronomer Tycho Brahe, who first coined the
term nova, for "new star", not realizing he was in fact witnessing the
violent end of an unknown star. It has long been believed that type 1a
supernovae are the death throes of a white dwarf star. But all modern
ones have been so distant that it has not been possible to see what had
been there beforehand."
