Earth sciences news on Phys.org
I just checked lecture 26 Venus, http://www.astro.lsa.umich.edu/users/cowley/lecture26/
which is my pet planet. But I think the current scholar view is somewhat different from the lesson, especially pertaining the water and the Urey reactions.

I'm not impressed, I'm afraid.

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...

Thread '(Unprecedented?) Cluster of earthquakes in Greek islands'

These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
