White Dwarf
Not an obscure member of Snow White's entourage, but a former star that has first evolved from being a Sun (much like our very own in the solar system) and winds up annihilating its nearby planets (in our case Mercury and Venus).
SDSS 1228 1040
Not an obscure mathematical formula to calculate your taxes, but the name of a white dwarf that was spotted about 463 light years from our Solar System in the constellation Virgo. Scientists found it to be surrounded by metal-rich gas, components of a common asteroid seen in our own solar system.
Now where do these all lead us to? If as the astrophysicists at Britain's Warwick University suspect, this star was part of a planetary system with an asteroid belt, then it could serve as a model for what will happen to our own solar system in five to eight billion years when the sun becomes a white dwarf. Which means, we're all going to burn eons from now.
Creepy, but of course it's too early to worry about that, eh.

Great Post!
Have you noticed that the thing about definite science [discoveries] is that once something is defined, definitely - it shifts and changes to something else - ready to be re-defined .. in-fin-ite.
Anyway, I remember getting a six-DVD pack out from the library hosted by Sam Neil called Space. In it he tells how our sun is currently expanding in the final bloat, before it eventually implodes - Kaaboom!!!.
The conclusion is not to worry, because we will all fry to a crisp on Earth before it finally blows up anyway due to a close proximity and we will have to vacate to Mars in order to escape the increase in temperatures. Do you think that's why they are building the space station? NO doubts about it wiping out Mercury and Venus, for sure! This 'cheery' news is delivered with great graphics btw ... Bing Bala Boom! I absolutely adored it. It's been out on loan since because I tried a couple times to get it again. I'll have to go the the ABC shop or something to get it.
Sorry, I mention it to you becuase I think you'd love it, if you haven't seen it already?
I love this stuff as I said, a great post and picture!
Cheers
