Contrary to a popular scientific notion, there was enough mixing in the early solar system to transport material from the sun's sizzling neighborhood and deposit it in icy deep-space comets.

Stardust, the NASA spacecraft mission, was given that name in hopes that the seven-year journey to capture comet samples would bring back to Earth, well, stardust.

Layers on Mars are yielding history lessons revealed by instruments flying overhead and rolling across the surface.

NASA officials have cleared the space shuttle Discovery to return home Friday, but the U.S. space agency is not sure where the spacecraft will land.

Scientists are announcing this week their detection of a June 14 gamma-ray burst that probably signals a hitherto undetected type of cosmic explosion. The hybrid gamma-ray burst probably created a new black hole, but the details of how the explosion occurred are unclear.

Ever since NASA's Stardust spacecraft delivered a payload of comet dust to Earth on Jan. 15, 2006, scientists by the hundreds have been clamoring for samples.

NASA Ames Research Center and Google have signed a Space Act Agreement that formally establishes a relationship to work together on a variety of challenging technical problems ranging from large-scale data management and massively distributed computing, to human-computer interfaces.

Scientists explore the grains retrieved by NASA's Stardust spacecraft from comet Wild 2 at 2004. The analysis make scientist to change their opinion about cold emissaries and the whole solar system.

Our Solar System may have been created in a gigantic mixing process far more extensive than previously imagined, according to research published today.
