Titan's Surface Organics Surpass Oil Reserves on Earth

02.13.08-- Saturn's orange moon Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth, according to new data from NASA's Cassini spacecraft.


Cassini to Image Huygens Landing Site

02.14.08-- A little more than three years after the Huygens probe landed on Saturn's moon Titan, Cassini's radar instrument will get another look at the area where it landed during a flyby on Feb. 22.

Possible Progenitor of Special Supernova Type Detected

Images from the Chandra and Swift observatories show evidence for possible detection of a binary star system that was later destroyed in a Type Ia supernova explosion. The progenitor to a Type Ia supernova has never been detected, but promises to answer important questions about the exact configuration and trigger for these explosions.

Dawn Spacecraft Begins Interplanetary Cruise Phase

12.18.07 -- NASA's Dawn spacecraft has begun the interplanetary cruise phase of its 8-year, 3-billion mile journey to asteroid Vesta and dwarf planet Ceres

Gravity Probe B is the relativity gyroscope experiment developed by NASA and Stanford University to test two unverified predictions of Albert Einstein's general theory of relativity.

Astronomers Uncover One of the Youngest and Brightest Galaxies in the Early Universe

NASA’s Hubble and Spitzer space telescopes, with a boost from a natural “zoom lens,” have uncovered what may be one of the youngest and brightest galaxies ever seen in the middle of the cosmic “dark ages,” just 700 million years after the beginning of our universe.

Mars Rovers Sharpen Questions About Livable Conditions

02.15.08 -- Like salt used as a preservative, high concentrations of dissolved minerals in the wet, early-Mars environment known from discoveries by NASA's Opportunity rover may have thwarted any microbes from developing or surviving.

As MESSENGER sped by Mercury on January 14, 2008, the Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) captured this image before its closest approach with the planet. The scene is near Mercury's terminator (the line between the sunlit day side and dark night side of the planet), where shadows are long and height differences accentuated, revealing rising crater walls that tower over the floors below.

New Horizons Sees Changes in Jupiter System

This is a montage of New Horizons images of Jupiter and its volcanic moon Io taken during the spacecrafts Jupiter flyby in early 2007.New Horizons’ voyage through the Jupiter system earlier this year provided a bird’s-eye view of a dynamic planet that has changed since the last close-up looks by NASA spacecraft.
