New Dwarf Planet Candidate Discovered at Solar System's Edge: Could a Hidden Planet Be Orbiting Farther Out?

The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars [...]

All Eyes on Comet ISON as It Plummets Toward Thanksgiving Day Brush With the Sun

VIDEO: Comet ISON moves ever closer to the Sun in this movie from the ESA/NASA Solar and Heliospheric Observatory, captured in the early hours of Nov. 27, 2013. A coronal mass ejection explodes off the Sun; it is unlikely to damage ISON even if they cross paths. Image Credit/Caption: ESA/NASA/SOHO

Carbon Worlds May Be Waterless, Finds NASA Study

This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in carbon — and dry. Chances are low that life as we know it, which requires liquid [...]

NASA's Comet-Chasing Deep Impact Mission Is No More

Nine years ago NASA launched a spacecraft to do something that had never been done at any point in recorded history: to visit a comet and punch a hole in its face to investigate the surface and interior composition [...]

JPL Attempting to Reestablish Communication With Comet Hunter Deep Impact

Gravity Controls Enigmatic Moon's Geysers

These images from NASA’s Cassini spacecraft show how the pull of the planet affects the amount of material ejected by geysers on Saturn’s moon Enceladus. It turns out that the moon launches more spray when it is farther away from Saturn. Image Credit: NASA/JPL-Caltech/University of Arizona/Cornell/SSI

Saturn’s 314-mile-wide icy moon Enceladus has been teasing [...]

Comet ISON Fizzes Like a Soda Pop

Coming soon to a region of space near you: comet ISON, which is expected to put on a spectacular show toward the end of the year. Currently, ISON is about 258 million miles from the Sun, between the orbits of Jupiter and Mars. Its tail already stretches out more than three-quarters of [...]

'Mr. O' (NASA's Mars Reconnaissance Orbiter) Makes Remarkable New Discoveries From Mars Orbit
