Gale before Curiosity: What we knew and what the rover may reveal
The first comprehensive analysis of what we knew about the Gale crater on Mars before the recent landing of space rover Curiosity has been published by the International Journal of Astrobiology (IJA).
Mathematicians show how shallow water may help explain tsunami power
(Phys.org)—While wave watching is a favorite pastime of beachgoers, few notice what is happening in the shallowest water. A closer look by two University of Colorado Boulder applied mathematicians has led ...

Vesta in Dawn's rear view mirror
(Phys.org)—NASA's Dawn mission is releasing two parting views of the giant asteroid Vesta, using images that were among the last taken by the spacecraft as it departed its companion for the last year.
Picky penguins: Does mate choice depend on genes that help resist disease?
Magellanic penguins have a high level of variation in genes associated with the ability to fight infectious disease, but a recent study found that the mechanism the penguins use to ensure that diversity is ...
The Kuiper Belt at 20
Planetary science is celebrating the 20th anniversary of the discovery of the Kuiper Belt. That came in 1992, when the first Kuiper Belt Object (KBO) was discovered.
