Bright spots with no temperature anomaly in infrared increase the puzzle about what the bright spots are.
On June 6, 2015, NASA/JPL released a new image from the DAWN spacecraft at the lowest altitude to date: 2,700 miles above the surface. Triangular patterns of bright spots and no temperature anomaly in infrared increase the puzzle about what the bright spots are. Next closest altitude will be 932 miles by early September. Stay tuned for more Earthfiles News updates.
Gold arrow points at one of two triangular patterns of bright spots
in the Ceres crater where brightness 40 times background has persisted for
at least ten years since the Hubble Telescope’s blurry image of Ceres
in 2004 showed the same bright crater. This June 6, 2015, image
was taken by the NASA/JPL Dawn spacecraft in its lower June orbit
of 2,700 miles above the Ceres surface.
