Re: Enceladus Ice Geysers Imaged

Hello Stra,

I wasn't abreast of the theories behind the plumes (other than
reading speculative thoughts on cryovolcanism as they might be applied
to Titan), they just looked like ice geysers to me so that's what I
called them (the resemblance visually to a geyser is quite strong,
from Iceland's to old-faithful). I wasn't aware that there was a

While this group might not be the best place to discuss various
theories I feel compelled to point out that the term "geyser" in its
meaning of the word in this case is just that, a theory. The notion of
the "plumes" being extremely hot (too hot in fact) and the "geysers"
moving around (geographically) places this theory under a giant

Wow,
I remember when when I first saw a post for recruitment of an
intern to fly on SOFIA in 1997 (or sometime around that time).
I was all enthusiasm with no qualifications so I did not
apply then. Looking back, I am glad I did not have to wait
13 years for the flight :-)

Imagine cutting retractable doors in the side of a 747 airliner, installing
a 17-ton telescope, and flying to the stratosphere to solve one of
astronomy's greatest puzzles. That's what NASA and the German Aerospace
Center plan to do with a cutting-edge airborne observatory named SOFIA.
