Donald Yeomans There apparently is a great deal of interest in celestial bodies, and their locations and trajectories at the end of the calendar year 2012. Now, I for one love a good book or movie as much as the next guy. But the stuff flying around through cyberspace, TV and the movies is not […]

Cassini’s Swoop over Enceladus: First Morsels of Science Coming Back Now

Cassini’s Swoop over Enceladus: First Morsels of Science Coming Back Now

Bonnie J. Buratti Phew! We made it through the deepest swoop yet down into the plume of Enceladus, the encounter we call “E7″ because it’s the seventh targeted flyby of Enceladus. But now we have our work cut out for the next few weeks as we pore over the data, painstakingly analyzing every signal to […]

Taking the Plunge: Cassini Soars by Enceladus

Bonnie J. Buratti After so many close flybys of Enceladus, we’re starting to feel as if this little moon of Saturn is an old friend. But during the encounter planned for Nov. 2, 2009, we are going to get up-close and personal. Cassini is going to take its deepest dive yet into the plumes spewing […]

Tackling Clouds for Improved Predictions of Future Climate

Tackling Clouds for Improved Predictions of Future Climate

Hui Su Clouds are among the most fascinating natural phenomena and have inspired countless works of literature and art. Their ever-changing forms make them a great challenge to atmospheric scientists working to predict how our climate will change in the future in response to increasing greenhouse gases such as carbon dioxide. Clouds occur at many […]

Comets and Life On Earth

Comets and Life On Earth

Donald Yeomans With the recent discovery of the amino acid glycine in the comet dust samples returned to Earth by the Stardust spacecraft, it is becoming a bit more clear how life may have originated on Earth. Water is a well-known ingredient in both comets and living organisms, and now it appears that amino acids […]

Five Things About Viewing Mars in August

Five Things About Viewing Mars in August

Jane Houston Jones If you’re like me, you may have received an e-mail this summer telling you go outside on August 27 and look up in the sky. The e-mail, most likely forwarded to you by a friend or relative, promises that Mars will look as big as the moon on that date, and that […]

The Lowdown on Jupiter’s Black Eye

Glenn Orton We’ve had such great feedback and comments to our earlier post about the recent impact at Jupiter that we wanted to give you more details, plus answer some questions. My name is Glenn Orton, a senior research scientist at JPL. My colleague and fellow JPL blogger Leigh Fletcher is on a well-deserved vacation […]

Five ‘Holy Grails’ of Distant Solar Systems

Five ‘Holy Grails’ of Distant Solar Systems

Angelle Tanner Angelle Tanner, a post-doctoral scholar at JPL and Caltech, studies planets in distant solar systems, called extrasolar planets. The golden prize in this field is to find a planet similar to Earth – the only planet we know that harbors life. While more than 350 extrasolar planets have been detected, most are gas […]
