Carl Sagan reborn! Rather close anyway. You da man!

One thing I’ve wondered: we can see the Milky Way, yes, but it’s really very faint, as compared to the beautiful images we see from, say, Hubble. Ditto other galaxies.

So here’s my question: are galaxies really as bright & pretty as they look in most pictures we see, or is this chiefly due to the long exposure time for the image, and the real thing, if we were out ther looking at it, is actually really dark?

Just the curiosity of some random 28-year old webmaster.

So cool! I’m starting to regret having chosen graphic design instead of astronomer. I told my dad that when I was a kid that I wanted to be astronomer, bad idea. He asked me how I was going to make a living as an astronomer.

Anyway, I can always use a telescope. Marvellous device! Every time I see the night sky, I really really feel something very special. Sometimes, as if something is calling me. And I bet I am not the only one

Great description of our Galaxy.

I am looking forward to more.

As a possible topic how about talking about what will happen when we traverse the Galactic plane in the near future.

This was wonderful. Thanks!

I’m connected through dialup and it played fine. The second time. Just turn the sound off so you don’t get bits of dialog, open another tab and do something else while it plays through once.
