New Evidence For Hidden Water Reservoirs And Rare Magmas On Ancient Mars

A new study explores how variations in Mars’ crustal thickness during its ancient history may have influenced the planet’s magmatic evolution and hydrological systems. The research, published in Earth and […]

Liquid On Mars Was Not Necessarily All Water

Dry river channels and lake beds on Mars point to the long-ago presence of a liquid on the planet’s surface, and the minerals observed from orbit and from landers seem […]

The Role Of Ammonia In The Distribution Of Volatiles In The Primordial Hydrosphere Of Europa

The presence of a hydrosphere on Europa raises questions about its habitability, and studies of its volatile inventory can provide insight into its formation process. Different scenarios suggest that Europa’s […]

McGill High Arctic Research Station Photo Report – Dale Andersen: 8 April 2009 Colour Peak Springs

There are several regions on Earth where mean annual temperatures are well below freezing and yet liquid water persists. Such polar regions provide excellent analogs to study the hydrological cycle […]
