Shedding New Light On the Solar System: Celebrating 25 Years of Hubble Science (Part 2)

A series of images of Uranus and Neptune that were taken with the Hubble Space Telescope. The top row reveals the ice giant planets in natural colors, showing the planets as they would appear if we could see them through a telescope. The images at the bottom were taken with certain types of different […]

The Dawn spacecraft is now very close to the dwarf planet Ceres, but there are some interesting new findings from its previous visit to the asteroid Vesta. Curved gullies on its surface suggest that small amounts of water may […]

Surprisingly Bright Cloud Systems and Extreme Storms on Uranus Puzzle Astronomers

Infrared images of Uranus at wavelengths of 1.6 (left) and 2.2 microns (right), that were obtained on Aug. 6, with the Adaptive Optics system on the 10-meter Keck II telescope on Mauna Kea in Hawaii. The white spot is an extremely large storm that was brighter than any feature ever recorded on the planet […]

Comet's Close Encounter With Mars Yields New Insights Never Before Seen

This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT Oct. 19, 2014. Image and Caption Credit: NASA, ESA, PSI, JHU/APL, STScI/AURA

When Comet C/2013 A1 Siding Spring made its closest […]

New Moon: LRO Discovers Evidence of Young Lunar Volcanism

A series of surface features called irregular mare patches that have been recently discovered on the Moon, are thought to be remnants of small basaltic eruptions that are indicative of lunar volcanic activity as recent as several million years ago. This image by the Lunar Reconnaissance Orbiter shows one such feature, called Maskelyne. Image […]

Plate Tectonics May Increase Chances for Life on Europa

Europa, with its subsurface ocean, and now evidence for plate tectonics, is a primary goal of exploration in the search for alien life. Processed image copyright: Ted Stryk. Image Credit: NASA/JPL-Caltech/Ted Stryk

Jupiter’s moon Europa is a fascinating little world, but particularly so for one reason: water. It’s deep alien ocean underneath the surface […]

Rainfall on Titan May Create Propane Aquifers, Study Suggests

Saturn’s largest moon, Titan, is a very alien yet eerily Earth-like world, with rain, rivers, lakes, and seas; seen from above, the landscape has a familiar look to it. But […]

Titan's Hidden Ocean Might Be as Salty as the Dead Sea
