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 […]

Comet 67P/Churyumov–Gerasimenko, or 67P, has been the focus of intense study by the Rosetta spacecraft since 2014. One of the key mysteries scientists […]

Ceres Reveals Eye-Like Bright Spots, Mr. Spock Explains Dawn

This image was taken by NASA’s Dawn spacecraft of dwarf planet Ceres on Feb. 19 from a distance of nearly 29,000 miles (46,000 kilometers). It shows that the brightest spot on Ceres has a dimmer companion, which apparently lies in the same basin. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

A scientific mystery on dwarf planet Ceres—worthy of investigation […]
