hopefully there won't be any spiders

Curiosity is making me curious. What would it feel like to stand on the surface of Mars? Let's say, first of all, it's without a space suit -- what would kill me first? The carbon dioxide in the atmosphere? The temperature? Then, if we found some way to breathe and function normally, what would it be like to be there? Would it be hot? Cold? Too windy to stand up? Paint a picture for me, if you can.

To infinity and beyond

If the expanse of the universe is infinite, does it necessarily follow that the number of stars and planets is also infinite?

Illustrations for child's space-themed mural?

Our son is getting too old for the animals on his wall, and we'd like to do a space theme (rockets, the real planets, etc). We've found that by enlarging an image and printing it out on clear label paper, we can make murals using our favorite illustrations, either found online or in books (technique originally posted here). So, we're looking for cool illustrations of the planets, rockets, etc. Preferably with a Mary Blairish, 1950's feel. Any suggestions, either on the internet or book recommendations?

Buying a Telescope for My Son

I want to buy my son, who is turning six, a telescope for his birthday. I don't want to spend a fortune, but one site I looked at for advice said anything less than $300 is a piece of junk. Anyone have any advice (including specific models) on one I can by this budding astronomer for $100 or less?

If the sun's gravity is so strong as to keep whole planets circling it in orbit, how come light and heat can escape?

ScientificIlliterateFilter: If the sun's gravity is so strong as to keep whole planets circling it in orbit (even ones million of miles away), how come light and heat (incredibly fragile things compared to planets) can escape as rays (or whatever they are)?
