Title: Bright Supernova in M82
Post by: Rick on Jan 22, 2014, 21:36:22
Bright Supernova in M82

A spectrum reported a few hours ago by Yi Cao and colleagues (Caltech) suggests that the supernova may still be two weeks away from reaching its peak brightness. The spectrum shows it to be a Type Ia supernova — an exploded white dwarf — with debris expanding at 20,000 kilometers per second. It is reddened, and hence must also be dimmed, by dust in M82 along our line of sight.

And probably a bunch of other places, too...

Good target for imaging if the clouds go away...

I particularly like this bit...

Quote"The weather was closing in, with increasing cloud," Fossey says, "so instead of the planned practical astronomy class, I gave the students an introductory demonstration of how to use the CCD camera on one of the observatory's automated 0.35–metre telescopes."

A lucky choice, that night. :)

Just shows what can be done in light polluted locations!

Shows what can be done if you don't let the weather put you off... :brolly:
