Cassini Image May Reveal Historic Birth of Icy Saturn Moon

From NASA/JPL: “The disturbance visible at the outer edge of Saturn’s A ring in this image from NASA’s Cassini spacecraft could be caused by an object replaying the birth process of icy moons.” Image Credit: NASA/JPL-Caltech/Space Science Institute

The Cassini spacecraft, a flagship-class mission that is a cooperative project between NASA, the European Space [...]

The Sea of Enceladus: Cassini Confirms Underground Ocean on Saturn's Geyser Moon

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 [...]

The Search for Alien Life Part 2: In the Realm of the Gas Giants

Beyond the main asteroid belt lie the giant planets Jupiter and Saturn and their impressive retinues of moons. What chances for life are out here in the frozen wastes of the solar system? At first glance, you’d imagine none. The [...]

Some Exoplanets May be Even More Habitable Than Earth

Some rocky exoplanets may be warmer and more geologically active than Earth—and perhaps even more habitable. Image Credit: J. Pinfield / RoPACS / University of Hertfordshire

In the search for life elsewhere, the Earth is typically used as a standard against which other planets, or moons, are compared. Since our planet is teeming with [...]

Planets Orbiting Dying Stars Are Probably Dead Too

If you are searching for other inhabited worlds, almost any kind of star may do according to current findings, except perhaps for white dwarfs. As it turns out, planets [...]

Waterworlds: The Search For Life in the Outer Solar System

Until relatively recently, it was thought that the best, or perhaps only, place to look for life elsewhere in the solar system was Mars. The other inner planets were much [...]

It’s been fifteen years since Cassini launched to Saturn. A joint program with the European Space Agency and the Italian space agency, the Cassini-Huygens mission left Earth on October 15, 1997. It flew by Venus twice, swung back by [...]
