A Very Alien Moon: NASA Celebrates 12th Anniversary of Huygens Landing on Titan

Mosaic of images taken by Huygens during its descent to the surface of Titan, from an altitude of about 6 miles (10 kilometers). Riverbeds formed by liquid methane can be seen near the center of the image. Image Credit: ESA/NASA/JPL/University of Arizona

Twelve years ago today, one of the most incredible space missions ever […]

Ancient Water World: Tectonics on Pluto's Moon Charon Point to Frozen Subsurface Ocean

Charon is Pluto’s largest moon and, despite being so cold and remote from the Sun, has been revealed to be a fascinating and active world, just like Pluto itself. Residing in the far outskirts of the Solar […]

Cassini Sends Back Spectacular New Images from First Ring-Grazing Orbit at Saturn

Saturn’s northern hemisphere up close: new image taken by Cassini on Dec. 3, 2016, showing small details in the turbulent atmosphere, including one corner of the “hexagon” with central cyclone. It was taken at a distance of about 240,000 miles (390,000 kilometers) from Saturn. Photo Credit: NASA/JPL-Caltech/Space Science Institute

The Cassini spacecraft has successfully […]

Gateway to the Ring-Grazing Orbits: Cassini Conducts New Flybys of Titan and Enceladus

The Cassini mission to Saturn has been one of the most successful planetary missions ever, revealing the ringed giant and its moons as never before. Sadly, that mission is scheduled to end Sept. 15, 2017, and in preparation the spacecraft […]

'Cracked and Tipped Over' Pluto Has a Subsurface Ocean: New Evidence From New Horizons

For a long time now, there has been growing interest in sending a mission back to Jupiter to better study one moon in particular: Europa. Previous missions such as Voyager and Galileo showed us this world up close for the first time, […]

Does Pluto Have a Subsurface Ocean? New Research Says Probably

So-called “waterworlds” have been found to be surprisingly common in the Solar System—small icy moons which have ice crusts but oceans of liquid water below the surface. These include Jupiter’s moons Europa […]

All Good Things: Countdown Begins Toward Cassini's 'Grand Finale' Around Saturn

Artist’s concept of Cassini’s final orbits between the Saturn’s innermost rings and the planet’s cloud tops. This set of orbits will consist the last leg of Cassini’s mission, called “The Grand Finale,” which will culminate with a plunge on Saturn’s atmosphere in September 2017.

It has become something of […]

Pluto Once Had Rivers and Lakes of Liquid Nitrogen, New Horizons Data Suggests
