Supernova Birth Observed From Orbiting Telescope 94
FiReaNGeL writes "Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but no one had witnessed a star dying in real time — until now. While looking at another object in the spiral galaxy NGC 2770, using NASA's orbiting Swift telescope, scientists detected an extremely luminous blast of X-rays released by a supernova explosion. They alerted 8 other telescopes to turn their eyes on this first-of-its-kind event. 'We were looking at another, older supernova in the galaxy, when the one now known as SN 2008D went off. We would have missed it if it weren't for Swift's real-time capabilities, wide field of view, and numerous instruments.'" Bad Astronomy has an excellent, well-illustrated story about the discovery as well. I Don't Believe in Imaginary Property contributes a link to the BBC's coverage, and adds a nugget gleaned from Ars Technica: "SN 2007uy's collapse caused an X-ray burst of about 10^39 joules, most likely due to the 'shock break out' when the energy of the core's collapse finally reached the neutron star's surface."

Heavier elements (like uranium [wikipedia.org]) are actually created in the supernova event itself:
So this observation is actually recording the actual origin of all the elements heavier than iron. All the jewelry and aerospace materials you've ever seen, all the copper you use in wiring and plumbing, all elements [wikipedia.org] with atomic numbers from 27 (cobalt) through 94 (plutonium) were made in crucibles like the one we just took home movies of.

I understand that astronomers have been wanting to gather as much data as they can from as many telescopes as they can on supernovae as they appear, and have organised lots of telescopes en masse before, I just wonder by what means it's achieved.
I also think that it would be incredibly cool if, in the dusty control room of an observatory up a mountain in Hawaii or somewhere, there was a big red button labeled "push in case of supernova", which grabbed the co-ordinates currently being observed, and took over every other telescope on the planet to point at them.
Also, have they done interferometry with this data? because that would be an awesomely large telescope diameter (and awesomely small resolution angle).
