Those were pretty cool. I've seen most of them as they came out, but I had missed the rocket-aurora-laser one :)
Neat.
Anyone here into amateur astronomy - optical, radio, etc?
"Everyone wants to be an AM Gangsta until it's time to start doing AM Gangsta shit."
I belonged to the 3M amateur club in Austin (which was open to local hams) and they made me the program chairman one year. I found a speaker from the University of Texas to give a speech on radio astronomy. It was mind boggling. The degree of focus they can get with large radio antenna arrays is pretty mind boggling for astronomy through the atmosphere. They also explained that much of the noise you get when you plug your antenna in at 28MHz is from space (when the band is otherwise dead and you have no power line noise). He discussed the frequency windows. This was about 20 years ago and I have forgotten a lot of them, but they know what frequencies are good for certain effects. I was blown away.
These pictures are really great. I think the Chandra project is dead now. I hope Hubble can keep going for some time.
Spectacular!
