The Question
(Submitted March 17, 1997)
I'm an undergraduate student in Physics and I would like to have some
information on extra-terrestrial life for my astrophysics project.
It would also be a help if you could propose some web sites.
The Answer
There has been quite a bit of work on extraterrestrial life, both
from a theoretical point of view and also based on the known
properties of the planets in our solar system, notably mars.
A place to start is the SETI institute.
We are
interested primarily in X-rays, gamma-rays, and cosmic rays
in astronomy, and so can claim no particular expertise in this area.
I hope that these references are some help.
