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
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 [...]

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 [...]

PASADENA, Calif — The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA’s Mars rover Curiosity.
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 [...]

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 [...]

Much talk of Mars these days seems to focus almost exclusively upon the multi-faceted Curiosity rover, as it unravels the mysterious geological past of Gale Crater, or upon the Opportunity [...]
NASA has used a camera on the Mars Reconnaissance Orbiter spacecraft to study how frequently the planet Mars is impacted by meteors. Image Credit: NASA / JPL
NASA’s Mars Reconnaissance Orbiter (MRO) has been kept busy counting the amount of impacts the Red Planet has to endure on a yearly basis. The number? More [...]
