Hagrid is in the House!

I've just put the finishing touches on my latest Wikipedia contribution: Supernova remnant G1.9+0.3.

NASA held a press conference today to announce the discovery of this object, the remains of a supernova that exploded about 140 years ago (relative to Earth time -- it actually exploded about 25,000 years ago, and the radio waves are just reaching us now). It's the youngest supernova we have yet found, which is very exciting to scientists, because most observed supernovae explosions in human history took place before the invention of radio and X-ray astronomy. The last supernova in the Milky Way Galaxy that could actually be observed visually from Earth took place in 1604.

I listened in to the press conference over the web, and when I saw that there was only a stub about the press conference on Wikipedia, with no details, I decided to write an article, citing sources and gathering pictures.

I am such a geek! ;-) But astronomy was always my first passion in life, I can think of no higher calling than to contribute to the greater sum of freely-available human knowledge!

Here's the complete list of everything I've written (or significantly contributed to) on Wikipedia.
