NASA: Extreme shrimp may hold clues to alien life

NASA: Extreme shrimp may hold clues to alien life

Originally posted on fox13now.com:
Shrimp crawling around rock chimneys spewing hot water deep in the Caribbean Sea may hold clues to the kinds of life that can thrive in extreme environments on other planets, NASA says. The shrimp are called Rimicaris hybisae (no, we can’t pronounce it either). They live in clumps on…

Extreme Shrimp May Hold Clues to Alien Life

Originally posted on Emma Versteegh:
Shrimp called Rimicaris hybisae at deep hydrothermal vents in the Caribbean seem to have different dietary habits depending on the proximity of other shrimp. Those who live in dense clusters like this one live off bacteria primarily, but in areas where the shrimp are distributed more sparsely, the shrimp are…

Santa Cruz

Earlier this month I gave a seminar at the University of California Santa Cruz, Department of Earth & Planetary Sciences, in their Whole Earth Seminar series. A very enjoyable experience. Their campus is a redwood forest, and the people were very welcoming and interested. Though, I maybe should have talked about shells instead of hydrothermal […]

The world’s deepest hydrothermal vents: An analog for Europa?

Two weeks ago a group of students from the University of Southern California visited JPL. They all did a summer program in ocean sciences. I was one of the people telling them what “real” ocean scientists do at JPL.

Previously unsuspected dietary habits of Rimicaris hybisae
