Coloring the Ice: Scientist Compiles First-Ever Global Color Maps of Saturn's Icy Moons From Cassini Data

A high-resolution color global map of Saturn’s moon Mimas, based on imaging data from NASA’s Cassini spacecraft. A set of new global maps of Saturn’s largest icy moons reveal the latters’ landscapes in unprecedented detail. Image Credit: NASA/JPL-Caltech/SSI/LPI

The first 50 years of planetary exploration have seen the successful completion of humanity’s epic, first […]

NASA’s CATS Instrument Ready to Study Effects of Clouds and Aerosols on Earth

Roughly the size of a refrigerator, CATS will use the same two laser wavelengths on NASA’s CALIPSO mission, 1,064 and 532 nanometers, and it will incorporate a third laser wavelength, 355 nanometers. This may provide more detailed information about the particles in Earth’s atmosphere. Image Credit: NASA

Take a good look up at the […]

Science, Research, and Dragon CRS-5 Preparations Top Busy Week on Station

The crew of the International Space Station watches live coverage of the launch of the inaugural test flight of NASA’s Orion spacecraft from the Kennedy Space Center in Florida on Dec. 5. The uncrewed capsule successfully splashed down in the Pacific Ocean four hours later after two orbits of Earth. Image Credit: NASA

Of Warm Gas and Galaxy Mergers: Collisions Between Galaxies Can Halt Star Formation, According to New Study

A composite image of the gravitationally interacting galaxies NGC 3226 (at the top) and NGC 3227 (bottom), which clearly shows the tidally generated large structures that surround them as a result of a past collision with a third galaxy. Optical wavelengths in the image are shown in gray scale. The infrared glow of dust […]

Strong Winds Explain Titan's Immense Dunes, According to New Study

Everything has to come to an end eventually—as the saying goes—and that has […]

NASA's Cube Quest Challenge Aims to Send Nanosatellites to Lunar Orbit and Beyond on First SLS Flight

Registration is now open for NASA’s latest Centennial Challenges technology prize competition, called Cube Quest Challenge. The competition will award up to a total of $5 million to any teams that will successfully demonstrate a CubeSat in-space operations and communications in lunar orbit and beyond. Image Credit: NASA

With the much-anticipated, first test flight […]

Airships are a unique form of transportation—giant, balloon-like, lighter-than-air vehicles which can stay aloft for extended periods of time. Their design makes them […]

NASA's Van Allen Probes Detect Life-Protective Electron Barrier Inside Earth's Radiation Belts

A visualization of the Earth’s radiation belts, based on data that were gathered by NASA’s twin Van Allen probes. The Earth is seen to be surrounded by the plasmapause (blue-green area) and the two main radiation belts further out (multi-color area). The boundary between the plasmapause and the inner edge of the outer belt […]
