[Rockhounds] A field guide to finding fossils on Mars. (open access paper)

Sun Mar 10 11:06:04 PDT 2019

The so called Drake equation is pure speculation (or as engineers call it:
anal extraction) with zero fact or data behind it. As Astronomers are now
getting a glimpse of real extrasolar planetary data they are tightening up
their limits for the so called habitable zone. It looks more and more like
what we have here on Earth. And less and less like what they are seeing in
their data. Red Dwarf stars are crossed off the list for one. Of course
they are seeing solar systems that have little resemblance to ours is other
solar system like ours even exist. They cannot see terrestrial mass planets
nor planets in orbits not close to their star. I think they are looking
forward to the James Webb telescope if it ever gets launched.

There is quite a bit of data hoping here, these fellows WANT to find
extraterrestrial live and they look at the data thru pink lenses in some
cases. This flap about red dwarves is a major example. They are flare
stars, their planets are tidally locked and the star puts out small amounts
of radiation almost all in the infrared spectrum. No UV which is thought to
give evolution a kick. And can plants function and do photosynthesis with
ir radiation--it doesn't seem likely. So why would you even dream that
these stars could be homes to life?
