Artist concept of Cassini at Saturn. Image credit: NASA/JPL NASA’s Cassini spacecraft will be flying within about 46 miles (74 kilometers) of Saturn’s moon Enceladus on Wednesday, May 2, aiming primarily to learn more about the moon’s internal structure. The f... More »
Jay Wilson Heefner II, an electrical engineer who contributed greatly to the Laser Interferometer Gravitational Wave Observatory (LIGO) project over the course of 18 years at Caltech, has died. He was 51. Before arriving at Caltech in 1994, Heefner had worke... More »
This artist’s concept depicts the moment that NASA’s Curiosity rover touches down onto the Martian surface. The entry, descent, and landing (EDL) phase of the Mars Science Laboratory mission begins when the spacecraft reaches the Martian atmosphere, about 81 m... More »
[Credit: NASA/JPL-Caltech] Observations from NASA’s Spitzer Space Telescope show that the Sombrero galaxy is actually two galaxies in one. With a halo of stars surrounded by the thin edge of a stellar disk, the galaxy resembles a big hat. But by observing in i... More »
