Seize the day: Solar eclipses will one day be a thing of the past

On Aug. 21, a total solar eclipse will sweep across the U.S., starting in Oregon and ending in South Carolina. It’s been nearly a century since a total solar eclipse touched both U.S. coasts. So how predictable are events like the Great American Eclipse? Phillip Nicholson, an astronomy professor at Cornell University who studies the […]

Saturn’s bulging core implies moons younger than thought

ITHACA, N.Y. – Freshly harvested data from NASA’s Cassini mission reveals that the ringed planet’s moons may be younger than previously thought. “All of these Cassini mission measurements are changing our view of the Saturnian system, as it turns our old theories upside down,” said Radwan Tajeddine, Cornell University research associate in astronomy and a […]

Chemical trail on Titan may be key to prebiotic conditions

ITHACA, N.Y. – NASA’s Cassini and Huygens missions have provided a wealth of data about chemical elements found on Saturn’s moon Titan, and Cornell scientists have uncovered a chemical trail that suggests prebiotic conditions may exist there. Titan, Saturn’s largest moon, features terrain with Earthlike attributes such as lakes, rivers and seas, although filled with […]

Saturn’s bulging core implies moons younger than thought

Freshly harvested data from NASA’s Cassini mission reveals that Saturn’s bulging core and twisting gravitational forces are leading some astronomers to believe that the ringed planet’s moons are younger than previously thought. “All of these Cassini mission measurements are changing our view of the Saturnian system, as it turns our old theories upside down,” said […]

Under Saturnian moon’s icy crust lies a ‘global’ ocean

ITHACA, N.Y. – Cornell University researchers have learned that a global ocean lies beneath the moon’s thick icy crust by measuring with precision the tiny wobbles of Saturn’s moon Enceladus – whose cosmic quavers are detectable only in high-resolution images taken by NASA’s Cassini spacecraft. Cornell planetary scientists have analyzed more than seven years worth […]

Lunar Eclipse: What you need to know for Tuesday

Gregory Sloan is a senior research associated at Cornell University’s Center for Radiophysics and Space Research and has been involved with launching and operating the Spitzer Space Telescope. He comments on the total lunar eclipse expected on Tuesday, April 15. He says: “We have a total lunar eclipse coming up in the wee hours of […]
