The outer Solar System has been a busy place lately, with the ongoing Cassini mission at Saturn and New Horizons’ recent spectacular flyby of Pluto. Literally in-between those two worlds, however, it has been […]

Closing In on Pluto: Dwarf Planet Shows Its Face and Heart

Whether a dwarf planet, plutoid, trans-Neptunian object or Kuiper Belt object, Pluto has emerged from the gloom to reveal her secrets. Image Credit: NASA-JHUAPL-SWRI

The newest image of Pluto, taken by New Horizons’ Long Range Reconnaissance Imager (LORRI) camera less than six days before closest approach. The long dark area called the “whale” is in the lower left and the brighter “heart” region is in the lower right. Image Credit: NASA/JHUAPL/SWRI

With less than six days remaining now […]

Saturn’s largest moon, Titan, has seas and lakes of liquid methane and ethane dotting its surface, but one question scientists have been trying to figure out is how the hollows in the ground, which hold the lakes, form to begin with. Now, a […]

'Ocean Worlds Exploration Program': New Budget Proposal Calls for Missions to Europa, Enceladus and Titan

With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, […]

Enceladus' Water Geysers May Be 'Curtain Eruptions' According to New Study

The water vapor jets on Enceladus are now thought to mostly be more like diffuse “curtains” rather than separate plumes. Image Credit: NASA/JPL-Caltech/SSI/PSI

The water vapor geysers on Saturn’s moon Enceladus are one of the most fascinating phenomena in the Solar System; the jets spray far out into space in a dazzling display unseen […]

Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for the […]

'Life Not As We Know It': New Research Shows How Exotic Biology May Be Possible on Titan

The search for life elsewhere has long focused on what we are most familiar with on Earth—in other words, “life as we know it,” or organisms which […]

Exploring an Alien Sea: NASA Designs Submarine to Send to Titan
