Anticipation is on the rise for a new crop of commercial suborbital spaceships that can serve the scientific and educational market. These reusable rocket-propelled vessels are expected to [...]
(PhysOrg.com) — Space physicists from the University of Leicester are part of an international team that has identified the impact of the Sun on Mars' atmosphere.

Writing in the AGU journal Geophysics Research Letters, the scientists report that Mars is constantly losing part of its atmosphere to space.
The new study shows that pressure from [...]

ScienceDaily (Mar. 12, 2010) — Meet asteroid 1999 RQ36, a chunk of rock and dust about 1,900 feet in diameter that could tell us how the solar system was born, and perhaps, shed light on how life began. It [...]
ScienceDaily (Mar. 11, 2010) — Take a bunch of fast-moving electrons, place them in orbit and then hit them with the shock waves from a solar storm. What do you get? Killer electrons. That's the shocking recipe revealed by ESA's Cluster mission.

Killer electrons are highly energetic particles trapped in [...]
The Cassini probe zooms past a cutaway section of Saturn's moon Titan in an artist's rendering.
Saturn's largest moon, Titan, is perhaps best know for its unique, hazy atmosphere and lakes of liquid methane.
But a new look at Titan's insides reveals even more oddities: Beneath the brittle crust of ice lies a layer of slush. Deeper [...]
Size comparison of our Sun, a low mass star, a brown dwarf, Jupiter, and Earth. Stars with less mass than the Sun are smaller and cooler, and hence much fainter in visible light. Brown dwarfs have less than eight percent of the mass of the Sun, which is not enough to sustain the fusion reaction [...]
The colored dots are clusters within one of four distance ranges, with redder colors indicating greater distance. Colored ellipses show the direction of bulk motion for the clusters of the corresponding color. Images of representative galaxy clusters in each distance slice are also shown.

The reddish glow from the city lights of Boulder, Colo., is the result in part of the light being scattered by haze particles. UW scientists have discovered unexpected chemistry involving the pollutants that make up the haze. (Credit: Phil Armitage)

A partial map of the distribution of galaxies in the Sloan Digital Sky Survey, going out to a distance of 7 billion light years. The amount of galaxy clustering that we observe today is a signature of how gravity acted over cosmic time, and allows as to test whether general relativity holds over these scales. [...]
