AstronomyExtrasolar Planet News: Superplanet or brown dwarf?
New observations of an oddball planetary system 150 light-years from Earth suggest that some planets either are superheavy, more than 17 times as massive as Jupiter, or that they form from disks of gas and dust that encircle not just a single star, but two starlike objects.

Planetary ScienceMartian water everywhere
Combining data taken from two craft orbiting Mars with images and spectra collected by one of the Mars rovers, a scientist has found evidence that a body of water greater in area than all the Great Lakes combined once covered the Red Planet.

AstronomyPlanet Signs? Sifting a dusty disk
Infrared spectra of a disk of debris surrounding the young star Beta Pictoris reveals three distinct bands of dust, suggesting the location of a possible planet flanked by belts of asteroids or comets.
