New Horizons has shown Pluto to be a diverse world, more so than many scientists had anticipated, with tall mountain ranges, vast glaciers, a blue-colored […]

Mystery Solved? Odd Bright Spots on Ceres Explained as Salt Deposits

False color view of Occator crater on Ceres, showing the unusual bright spots. The image was taken by the framing camera on NASA’s Dawn spacecraft from a distance of about 2,700 miles (4,400 kilometers). Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

There now might be a definitive answer to a puzzle which has intrigued both scientists and the […]

The Saline Slopes of Mars: NASA Confirms Evidence for Flowing Liquid Water

False-color image of RSL on slopes in Hale crater. The blue color is thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site […]

Haze Detected Above Mystery Bright Spots on Ceres

The intriguing bright spots on dwarf planet/asteroid Ceres have been fascinating the public and scientists alike for the past few months, and […]

Scientists Create Color-Based Catalog of Earthly Life Forms to Help Search for Alien Biology

A hypothetical rendering of colorful plant life on a habitable exoplanet. Although most such alien life, if it exists, found with this technique may be microscopic, it illustrates how analysis of color could help scientists learn more about the physical nature of alien biology.

The Lunar Reconnaissance Orbiter has identified trace amounts of helium gas in the Moon’s tenuous atmosphere. Using its LAMP (Lyman Alpha Mapping Project) instrument, it identified the gently glow of elemental […]

Of Polar Bears and Thematic Mappers: The 40-Year Landsat Achievement

Landsat 7, the most recent arrival in a family which began as the Earth Resources Technology Satellite, has operated from near-polar orbit since April 1999. In February of next year, it and the aging Landsat 5 will be joined by the next-generation Landsat Data Continuity Mission (LDCM). Image Credit: NASA

Twelve miles off the […]
