Two mystifying faces of Ceres These two views of Ceres were acquired by NASA’s Dawn spacecraft on Feb. 12, 2015, from a distance of about 52,000 miles (83,000 kilometers) as the dwarf planet rotated. The images have been magnified from their original size. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA
A fresh set of images of dwarf planet Ceres […]
Comparison of Ceres images taken from NASA’s Dawn spacecraft on Jan. 25, 2015, and the Hubble Space Telescope up to January 2004. What is the nature of the ‘White Spot’ visible in both images? What new features are being revealed by Dawn? Dawn Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA. HST Credit: NASA, ESA, J. Parker (Southwest Research Institute), […]
