Rotational Motion of Ceres
Rotational Motion of Ceres
Ceres, the first asteroid to be discovered, is by far the largest and most massive body in the main asteroid belt. NASA's Dawn Mission will be the first to reach Ceres and one of its main goals is to understand its thermal evolution and current state.Read More...
Atmospheric Modeling of Martian Methane Plumes: The Debate Continues
Atmospheric Modeling of Martian Methane Plumes: The Debate Continues
From recent observations, it has been suggested that there is evidence for the periodic (seasonal) release of methane occur from discrete surface locations on Mars, although the exact location and mechanism of release is still unknown.Read More...
Topography of Titan's Arctic Lake District: Implications for Subsurface Liquid Alkane Flow
Topography of Titan's Arctic Lake District: Implications for Subsurface Liquid Alkane Flow
By comparing the calibration of various overlapping Titan RADAR imagery, scientists on the Cassini RADAR instrument team were able to test a new model which is better able to estimate surface heights, elevations and subsurface phenomena within Titan's ArcRead More...
Numerical Simulations of Mantle Plumes on Venus: Implications for Mantle Viscosity, Water Content and Melting
Numerical Simulations of Mantle Plumes on Venus: Implications for Mantle Viscosity, Water Content and Melting
Venus is a planet with striking surface characteristics, including mantle plumes, which are hot, roughly cylindrical structures that rise from deep in the mantle of the planet.Read More...

NASA's GALEX Telescope Confirms Nature of Dark Energy
Dark energy is in a tug-of-war with gravity.Read More...
Oxygen Isotope Variation in Meteorite Provides Insight Into Planet Formation
Oxygen Isotope Variation in Meteorite Provides Insight Into Planet Formation
NASA scientists conducted research on a meteorite and have provided new evidence that the inner planets formed from materials spread far and wide in the early solar system.Read More...
Stardust-NExT Mission Delivers Striking Images of Man-Made Crater on Comet Tempel 1
Stardust-NExT Mission Delivers Striking Images of Man-Made Crater on Comet Tempel 1
The spacecraft made its closest approach to Comet Tempel 1 on Monday, Feb. 14, at 8:40 p.m. PST (11:40 p.m. EST) at a distance of approximately 178 kilometers (111 miles). Stardust took 72 high-resolution images of the comet.Read More...
Regional Lunar Surface Temperatures, Albedos, and Thermophysical  Properties from LRO's Diviner Instrument
Regional Lunar Surface Temperatures, Albedos, and Thermophysical Properties from LRO's Diviner Instrument
As LRO is pioneering NASA's efforts to renew exploration of the Moon, Diviner's temperature maps can be used to determine the thermal and physical properties of the Moon's surface, and therefore better characterize and assess the safety of landing sites.Read More...
Cassini Discovers Saturn to Vary its Energy Output
Cassini Discovers Saturn to Vary its Energy Output
Saturn is a changeable world that pumps out surprisingly variable amounts of heat from season to season and year to year, a new study has found.Read More...
WISE Captures Key Images that will help EPOXI Mission's Comet Encounter
WISE Captures Key Images that will help EPOXI Mission's Comet Encounter
NASA's Wide-field Infrared Survey Explorer, or WISE, caught a glimpse of the comet that the NASA's EPOXI mission will visit on November 4, 2010. The WISE observation will help the EPOXI team put together a large-scale picture of the comet.Read More...
