The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s illustration of the brights spots Occator crater and elsewhere, based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the influence […]

Mars is often referred to as a desert world, being bone-dry for the most part, with dust and sand blanketing most of the surface. Some regions are covered in […]

Curiosity Rover Confirms Ancient Lake(s) in Gale Crater on Mars

Sedimentary strata at the base of Mount Sharp as seen at the Kimberly location. The strata in the foreground dip toward Mount Sharp, providing evidence of the former lake-filled depression that used to exist before most of the mountain formed. Image Credit: NASA/JPL-Caltech/MSSS

Last week there was the exciting news that Mars still has […]

Curiosity Rover Continues Journey Up Mount Sharp After Science Observations at 'Marias Pass'
