Unveiling Rogue Planets

This video shows the scientists' best guess to date of what the surface of the protoplanet Vesta might look like.

This graphic shows in a series of three images how Saturn's rings, after they became tilted relative to Saturn's equatorial plane, would have transformed into a corrugated ring.

How can you communicate with Mars spacecraft when the Sun is in the way? Learn more about 'solar conjunction' in this 60-second video.

Surrounding Earth is a giant magnetic field called the magnetosphere. Its shape is defined not only by the planet's north and south magnetic poles, but also by a steady stream of particles coming i...
