Re: APOD: Bright Planetary Nebula NGC 7027... (2013 Aug 26)

I think it looks like a giant kernel of popcorn.
How about "Orville," in honor of Mr. Redenbacher, who provided us with sustenance many evenings in front of the TV.

Thank you all for taking the time to reply.
Now all I need is the time to go through the references you all gave me!

I'll share this information with science teachers and scientists I know here in Santa Cruz.
Thanks again...

Water On Mars?

Today (12/06/06) they announced that they think they've found definitive evidence of liquid water on Mars. Since the boiling point of water is a function of pressure, and since, as I understand it, the atmospheric pressure on Mars is about 90 times less than that on Earth, if any volcanic activity o...
