A look at the surfaces of 18 worlds in our solar system, all at the same scale.
Enlarge this image to its full 8000-pixel-square glory and lose yourself in it.
There are no spacecraft at Uranus or Neptune, and there haven't been for 30 and 25 years, respectively. So we depend on Earth-based astronomers to monitor them, including Damian Peach.
Today, New Horizons released a stunning new image of Pluto's backlit mountains and hazes. I explain how the image was taken with its Ralph Multispectral Visible Imaging Camera.
Last Friday the Internet received its first post-encounter pile of goodies from the New Horizons flyby of the Pluto system.
The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is almost a silent star at Mars. The latest MRO data release brought the total number of available CTX images to over 70,000, covering well over 90% of the Red Planet at a stunning resolution of 6 meters per pixel.
New Horizons has begun the long process of downlinking all the images it acquired during its July Pluto flyby.
The European Space Agency's Mars Express spacecraft captured a sweeping view of Mars' south pole, along with a region extending northward to Hellas Basin.
For months, Dawn has been steadily, methodically sharing dozens of images of brand-new sights of a previously unexplored icy world. For the last couple of days I've been making up for lost time, completely buried in the Dawn Ceres images, and I have some maps and 3D anaglyphs to share with you.
NASA’s Orion spacecraft completed a key parachute test Aug. 26 at the U.S. Army Yuma Proving Ground in Yuma, Arizona.
It has been a difficult wait for new New Horizons images, but the wait is almost over; Alan Stern announced at today's Outer Planets Advisory Group meeting that image downlink will resume September 5. In the meantime, a few space fans are making the most of the small amount of data that has been returned to date.
People often ask me to produce one of my scale-comparison montages featuring the small moons of the outer solar system. I'd love to do that, but Galileo's best images of Jupiter's ringmoons lack detail compared to Cassini's images from Saturn.
How and why does Curiosity take self-portraits? A look at some of the people and stories behind Curiosity's "selfies" on the occasion of the official release of the sol 1065 belly pan self-portrait at Buckskin, below Marias Pass, Mars.
NASA completed the sixth and next-to-last test firing of its RS-25 engine Thursday in Mississippi. Four RS-25 engines power the Space Launch System core stage.
A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet. It began with a 3D model of the comet created not by ESA, but by a space enthusiast, Mattias Malmer.
