How to Participate in a Supernova

Postby KnightOfFewWords » Mon Feb 03, 2014 11:34 pm

If anyone is interested, I've added a short article to the Caradon Observatory website, inspired by the recent supernova in Messier 82 - the appropriately named Cigar galaxy. It's certainly smoking now.

Hope you enjoy it, would be interested to hear your thoughts.

Nice article, easy to understand. Nice comparisons, like the sun's energy & a compost heap.

I liked this bit - The Earth and everything on it is composed of recycled stellar materiel, much of it from exploded stars. That's one of favourite science facts.

Cheers!

I had been following this from Virtual Astronomer on Twitter.

Virtual Astronomer ‏@VirtualAstro ·Jan 22
M82 (where the Supernova is) can be found in Ursa Major/ the Big Dipper and is a Starburst Galaxy.

Link should work now.

So would you say the galaxy is getting messier with all that star debris flying around.

Just realised I somehow failed to provide a link to the article I wrote, so here it is. If you'd like to hear why our Sun - like many middle managers - could be replaced by a giant compost heap, then read on.

Thanks for the comments. That bit of trivia is one of the reasons I'm interested in astronomy - you can choose to ignore the subject if you wish, but you can't opt out of it.

Wonder if Charles Messier was teased along those lines by his fellow astronomers? :lol:

Yes, M82 is a bit of a mess. Gravitational forces from near neighbour M81 have given it a good stir, triggering a massive burst of star formation.

"We are stardust.." Woodstock wasn't it?

Interestingly one thing I recall from my astrophysics lectures was a comparison between the Woodstock festival and stellar evolution. But that was so long ago the papyrus I wrote my lecture notes on has deteriorated...
