Scientists Investigate How Heat Rises Through Europa’s Ocean

by Rebecca Owen 10 January 20249 February 2024

A new study examines how heat may be transferred from the mantle, through the ocean, and into the icy crust of one of Jupiter’s moons—perhaps among the most promising places in our solar system to search for life.

Giant Planets May Be “Agents of Chaos”

Damond Benningfield, Science Writer by Damond Benningfield 18 December 202318 December 2023

Two studies suggest that some giants could make it difficult or even impossible for terrestrial planets to remain in a star’s habitable zone.

Microbe Goo Could Help Guide the Search for Life on Mars

by Grace van Deelen 8 December 20238 December 2023

Sticky substances secreted by microbes may help create landforms on Earth. And new research shows that these substances are more preserved in iron-rich sediment. Mars is decidedly iron-rich (it’s the Red Planet, after all), so the new study adds to evidence that microbe goo could help researchers explain landform creation there. “I think this is […]

Ancient Mars May Have Had a Cyclical Climate

by Vijay Shankar Balakrishnan 29 September 202329 September 2023

Hexagonal structures in sediments are evidence of repeated wet and dry conditions on the Red Planet.

Uranus is a shiny blue-white orb, slightly off center in this image. Its rings are seen nearly face on, and six bright blue dots show the six brightest moons of the planet. There are several reddish galaxies in the background.
