Hubble's planetary portrait captures changes in Jupiter's Great Red Spot

more »
Scientists using the NASA/ESA Hubble Space Telescope have produced new maps of Jupiter that show the continuing changes in its famous Great Red Spot. The images also reveal a rare wave structure in the planet's atmosphere that has not been seen for decades. The new image is the first in a series of annual portraits of the Solar System's outer planets, which will give us new glimpses of these remote worlds, and help scientists to study how they change over time.

What smacks into Ceres stays on Ceres, research suggests

more »
A new set of high-velocity impact experiments suggests that the dwarf planet Ceres may be something of a cosmic dartboard: projectiles that slam into it tend to stick. The findings could help explain characteristics of Ceres' surface.

Pebbles on Mars likely traveled tens of miles down a riverbed, study finds

more »
A University of Pennsylvania-led team uses a new method to determine that rounded pebbles on Mars traveled roughly 30 miles down an ancient riverbed, providing additional evidence for the idea that Mars once had an extensive river system, conditions that could support life.

A comet's tail may shed light on solar wind heating

more »
We can't see the wind, but we can learn about it by observing things that are being blown about. And by studying changes in a comet's bright tail of gas and ions, scientists are on the trail to solving two big mysteries about the solar wind, the supersonic outflow of electrically charged gas from the Sun's million-degree upper atmosphere or corona.
