I am in retired college teacher. I have taught geology, meteorology, chemistry, biology as well as astronomy. I guess I'm a person that just likes science and am a super generalist.

I ran into a link from a NASA page over to an Astrobiology webzine. In the article it referenced "sedimentary rock" on Mars. I don't really care about all the other claims of this article, some rather fantastic claims frankly. Rather I am interested in the use of the phrase sedimentary...

I want an exoplanet/exomoon with really deep depression. It would be the only place on that planet that's really habitable for humans without breating aid. Idea: -lower gravity (somewhere around 0.8 g) so the mountains should be able to be a bit taller -one supercontinent that's slowly...
