"All 786 known planets (as of June 2012) to scale (some planet sizes estimated based on mass). This [small box] is our solar system. The rest of these orbit other stars and were only discovered recently. Most of them are huge because those are the kind we learned to detect first, but now we’re finding that small ones are actually more common. We know nothing about what’s on any of them. With better telescopes, that would change. This is an exciting time.”

A large rock nicknamed Ridout dominates the rim of Odyssey crater—itself on the rim of the much larger Endeavour crater—in an August 13 picture by theMars rover Opportunity. The shot is among the first pictures taken by the rover since it arrived at Endeavour on August 9.
Ridout is thought to be a piece of material ejected from Odyssey during the impact that formed the comparatively small basin. The rock is 4.9 feet (1.5 meters) long—roughly the same size as Opportunity.

Deep fractures cut across the surface of the red planet in a recently released picture from the European Space Agency’s Mars Express orbiter.
The image captures part of the Nili Fossae region, a collection of curved faults and troughs northwest of the ancient impact basin Isidis. The curves tend to follow the outline of the basin, suggesting the fractures formed in the aftermath of the impact.

a planet forming in the debris around the star HL Tau. the protoplanet won’t condense into its final form—a ball of hydrogen and helium gas about the size of Jupiter called a gas giant—for at least another million years.
