Hi Sterling:
Some of my best friends (who are atmospheric scientists) do not believe in
global warming. I agree that there are just too many factors involved and you
can get almost any answer you want. While I personally believe that cutting
CO2 emissions is not a bad idea, it should be

where the Moon is (light from the Moon).

I have to keep this short since I have a journal article to review and a

they can't get out). I knew that.

Hi, Sterling:
Not to burst your bubble, but a Trojan asteroid is called such because it is
in a stable position with respect to the planet it is co-orbiting with.
There are 5 what are called Lagrange points: L, L2, L3, L4, and L5.
L1 is between the planet and the Sun (but lined up)

Hi Sterling:
1. According to the IAU, there are no free floating planets. Their official
name is sub-brown dwarf. This is probably to avoid people trying to name them

they may just be on the smallish end of brown

Hi Darren:
There were 5 or 6 articles that were released early by Space Daily. It is
not unusual for an article to be sent to the press, but embargoed until after
the journal comes out or the paper is given at a conference. It gives the

Hi Martin:
Ron is probably the expert on this, but meteoroids ablate as they come in so
most of the energy vaporizes the object (as fast as the heat is transferred
into the object). One does not want this for a spacecraft (would have to start

Mercury may not have a crust! What we see on the surface is more mantle-like
than crust-like in composition. In one theory, the crust and upper mantle were
