I thought I'd update the thread title to make this a place for discussion of all topics relating to astronomy, astrophysics, cosmology, spaceflight and space vehicles, interplanetary biology... etc. etc. So ask away and OCAU's sciencey Dr. Karl type bods will try and answer. (No guarantees given as to accuracy of answers... check your own facts before opening your mouth down at the pub!). Some useful and interesting links follow (will be added to over time). The OP is at the bottom. Post or PM me if you have any favourite sites you'd like to see added. I'd love to see this list continually evolve. Thanks.

I remember being so excited when Cassini/Huygens launched in 1997. I was 18. And then excited all over again when the first pictures came back... the first probe launched in my lifetime that I was aware enough to witness, both the launch and the resulting data. Life got in the way for a while, and my interest in this stuff was overrun by the humdrum stuff of daily existence. But every now and again I come across something like this that makes me sit in wonder for a little while, and I feel like a kid again. I love StumbleUpon.
