On June 30, 2004 (PDT), as mission controllers at NASA’s Jet Propulsion Laboratory held their collective breath, the international Cassini-Huygens mission successfully arrived in orbit around Satur...

Phillip Chamberlin expresses his enthusiasm for science and describes how he became a research astrophysicist.

Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion.

Dr. Bonnie Buratti describes her background as well as her role as a senior research scientist.

The shadow of Saturn's moon Tethys seems to disappear as it crosses the planet's rings, demonstrating variations in the density of particles across the rings.

Since the 1960’s, scientists have suspected that frozen water could survive in cold, dark craters at the Moon’s poles. 

The heavens often seem vast and unchanging as seen from Earth, but movement in the skies is the norm. The relative motions of both Cassini and Enceladus over a 15-minute period create the movement ...

Everyone likes to check the weather in a far away destination before they travel there. This is especially true for spaceflight, where the destination may be where no one has gone before.

After a 15-year wait, equinox arrived at Saturn and Cassini was there to witness the spectacle of light and shadow.
