This is an artist’s concept of the Planck spacecraft. Planck was launched with the Herschel spacecraft, though the two missions separated shortly after launch and operate independently from each other. Image credit: ESA/NASA/JPL-Caltech The High Frequency Inst... More »
Using a precision formation-flying technique, the twin GRAIL spacecraft will map the moon’s gravity field, as depicted in this artist’s rendering. Image credit: NASA/JPL-Caltech Twin NASA spacecraft that achieved orbit around the moon New Year’s Eve and New Ye... More »
A team of researchers at Caltech has devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thu... More »
NASA’s DC-8 airborne science laboratory soars over the Pinnacles near Mount Whitney, Calif., during a checkout flight in the winter of 1998. The aircraft will validate several specialized instruments, including a JPL airborne radar, for the future Global Preci... More »
Artist concept of Cassini spacecraft. Image credit: NASA/JPL Engineers with NASA’s Cassini mission are conducting diagnostic testing on a part of the spacecraft’s radio system after its signal was not detected on Earth during a tracking pass in late December. ... More »
Artist concept of GRAIL mission. Grail will fly twin spacecraft in tandem orbits around the moon to measure its gravity field in unprecedented detail. Image credit: NASA/JPL NASA will host a news conference at 10 a.m. PST (1 p.m. EST), on Tuesday, Jan. 17, to ... More »
Harold Zirin, a leading figure in solar astronomy and professor of astrophysics, emeritus, at Caltech, passed away on January 3. He was 82. Zirin was a pioneer in nearly all areas of solar astronomy, including solar radio astronomy. In particular, he made sign... More »

Chemical cues are used to promote aggregation among roundworms (in black) on a petri dish. [Credit: Caltech/Jagan Srinivasan] Scientists have long seen evidence of social behavior among many species of animals, both on the earth and in the sea. Dolphins frolic... More »
Artist’s concept illustrations show (left) the Mars Science Laboratory spacecraft during its voyage from Earth to Mars and (right) the mission’s rover, Curiosity, working on Mars after landing. Image Credit: NASA/JPL-Caltech › Larger view NASA’s Mars Scienc... More »
This is an artist’s concept of NASA’s Mars Science Laboratory spacecraft during its cruise phase between launch and final approach to Mars. The spacecraft includes a disc-shaped cruise stage (on the left) attached to the aeroshell. The spacecraft’s rover (Curi... More »
This artist’s illustration gives an impression of how common planets are around the stars in the Milky Way galaxy. The planets, their orbits, and their host stars are all vastly magnified compared to their real separations. A six- year search that surveyed mil... More »
