Re: CU: An ancient ocean may have covered one-third of Mars
Definitely interesting.
I find it remarkable, however, that a planet which ought to have been considerably colder than the Earth had one of its polar regions covered in liquid water. Any thoughts?

Re: Hypothesis for the Great Deluge in 9500 BC
I have heard that what is now the Mediterranean was once dry land where people lived and livestock grazed. Then, very suddenly, the Atlantic Ocean broke through the Sound of Gibraltar, and the land inside was flooded extremely quickly. This event may have lived in memory and given rise to stories ab...

Re: Recent Submissions: 2010 June 14-15
NGC 5746 is a nice-looking galaxy, to be sure. It has a very nice and striking shape. But to me it is a boring galaxy, because it is all monocolored: it is all yellow through and through, because its brown dustlane can be considered just another form of yellow, though a darkened one. There is no sta...

Re: Is the sun getting bigger, Right Now!
And that's what we are reduced to when it comes to pondering the question of extraterrestrial life - believing, thinking, guessing. Proving the existence of extraterrestrial life might well be hard, if that life doesn't look like we expect life to look, and if it exists in places where we have a har...

Re: Recent Submissions: 2010 June 10-13
By the way, since Gendler's (Hubble-based) image has a very different color balance than Gerber and Hager's image, which color balance is the best? In my opinion there can be no doubt that Gerber and Hager's color is better. I've said it before and I'm saying it again, the Hubble people can't do col...

Re: Is the sun getting bigger, Right Now!
I just bought the June issue of Astronomy magazine. On the cover there is a deeply red-orange :evil: picture of the Sun,, with the following caption: Is the SUN an oddball star? The article in the magazine says that while it is easy to find analogs of the Sun in our cosmic vicinity (that is, it is e...

Re: CU: An ancient ocean may have covered one-third of Mars
Mars may have abundant water in the past, but if it did the water is all gone now, at least all the liquid water. To me, the most important lesson here is that while Mars may have had an ocean three billion years ago, the Earth has had an ocean for more than three billion years, and it is still ther...

Hah, I like it - Jupiter's Great Red Spot is a part of Jupiter's Great Red Spot! (And there is a very face-on center of a spiral galaxy in there, too. What galaxy is it, I wonder? Could it be, uh, M74? Any suggestions? No, wait - I think it is NGC 1232!)

Wow, that's three great submissions, Rob! I'm impressed. And yes - I particularly like Einstein in (or on) Hubble!
Just one question - couldn't you find a way to fit my favorite cluster, the Pleiades, into all that blue stuff of the Earth and the surroundings of the space telescope?

Thanks to Tycho Brahe's careful observations of the path of Mars across the sky, Johannes Kepler was able to show that Mars follows an elliptical orbit around the Sun. http://curvebank.calstatela.edu/birthdayindex/dec/dec14brahe/brahe2006.jpg Tycho Brahe.

It's official: It's the new interstellar greeting of the universe. Don't say hi. Say 6EQUJ5. Now if we only knew how to pronounce it.

I love the picture of Comet McNaught passing galaxy NGC 891! Note the fantastic color contrast between the blue-green comet and the very yellow, dust-reddened spiral galaxy.
