Churchilll On Aliens

An essay written by Winston Churchill has been discovered among his papers.  It was written in 1939, when Europe was sliding into war.

In the essay, Churchill speculates about life elsewhere in the universe, and lays out essentially the same logic scientists use today to argue advanced life may be fairly common.  He also wrote he saw no  reason to think humans were the only, or the most intelligent, advanced race in the cosmos.

Cryovolcanoes

Cryovolcanoes relax and disappear over time, a new study suggests.

They are principally made of water ice, and such ice is not structurally strong enough to support the mass of a mountain over time, so the ice slowly relaxes and the mountain goes away.
