Cosmic burp may end in star's suicide: Scientific American
"V445 Pup lies 250,000 light-years away from Earth. Its earlier
outburst, first spotted in November 2000, is the subject of a report
this week in the Astrophysical Journal. "

Star likely to become a Type 1a supernova - Physics Today News Picks
"V445 Puppis has been under a two-year observation by the European
Southern Observatory's Very Large Telescope. The star was discovered by
a amateur Japanese astronomer when it became visible as a nova in
November 2000. It is the only nova appearing that has no hydrogen and
provides the first evidence for an outburst on the surface of a white
dwarf dominated by helium.

"This is critical, as we know that Type Ia supernovae lack hydrogen and
the companion star in V445 Pup fits this nicely by also lacking
hydrogen," says Danny Steeghs, from the University of Warwick, and one
of the key team members observing the star. A earlier paper by
astronomers Mariko Kato and Izumi Hachisu that modeled the star's
behavior suggested as much."

At 250,000 light-years away, you did you write "within Milky Way"?

He's off by a factor of 10.

Yeah, I was thinking the same thing before I posted the links. 250,000
ly's would be 2.5 times larger than the diameter of the galactic disk.
However, I was willing to consider that it may have been one of the halo
stars of the MW. It was too far away to be in the disk of the MW, but
not far enough away to be part of another local group galaxy, such as
Andromeda.

However, it seems like it was a typo on Sci-Am's part.

Maybe it's just kinda "hangin'-out" in intergalactic space.
