Wiki fun…

That’s interesting… Wikipedia now has an astrochemistry category. It’s not very big… yet. I might have to head back into the world of Wiki and do some editing sometime.

Heterocycles

In organic chemistry, a heterocycle is any ring molecule containing one or more atoms other than carbon. Adenine (mentioned in a previous post) is quite a good example of a heterocycle. A lot of these have been searched for in … Continue reading

I got my exam results back! Special Topics in Chemistry 1: Astrophysical Chemistry; Solid State Materials Chemistry Mark: 74 That, unless I’m mistaken, is a distinction! Needless to say, I’m rather happy about that score. I think it’s worth a … Continue reading

The Sombrero Galaxy

My personal favourite galaxy, M104, the Sombrero Galaxy. Simply stunning, I’m sure you’ll agree, in this Hubble Telescope image. Discovered in 1781 by Pierre Méchain, the Sombrero is interesting because of that long dust lane you can see running across … Continue reading

Black Hole Orbits

Black holes are interesting things. Interesting because they make relativity start to break. Strange things happen like apparent faster-than-light motion (caused by pieces of space-time itself being pulled faster than light). At close enough distances, all things (even light) start … Continue reading
