Watching the birth and death of moonlets in Saturn's F ring

Posted by Emily Lakdawalla on 2010/07/22 09:09 CDT

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Bruce Betts: Kepler discovers its first five exoplanets

Posted by Bruce Betts on 2010/01/04 12:06 CST

Congratulations to NASA's Kepler mission team on their announcement of the discovery of its first five exoplanets (planets around other stars). All five are "hot Jupiters," meaning that they are the sizes of the gas giants in our solar system, but are extremely close to their parent stars.

Canto III: Hints of Equinox

Posted by David Seal on 2009/06/04 06:31 CDT

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

The Orbital Dance of Epimetheus and Janus

Posted by Emily Lakdawalla on 2006/02/07 11:00 CST

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.
