On February 26, some of the nation's leading scientists and researchers—including five Nobel laureates and members of all three National Academies—will gather at Caltech to discuss some of the most perplexing questions facing humanity.
Researchers at Caltech have discovered evidence for an ancient delta on Mars where a river might once have emptied into a vast ocean. This ocean, if it existed, could have covered much of Mars's northern hemisphere.
John Grotzinger, Caltech’s Fletcher Jones Professor of Geology and project scientist for Curiosity—JPL’s newest Mars rover, exploring the floor of Gale Crater—will describe its discoveries so far during a free public lecture on Wednesday, April 24.
Thanks to a new high-tech gadget, astronomers have observed four planets orbiting a star relatively close to the sun in unprecedented detail, revealing the roughly ten-Jupiter-mass planets to be among the most exotic ones known.
John A. Johnson, assistant professor of planetary astronomy at Caltech, received the 2012 Newton Lacy Pierce Prize at the 221st meeting of the American Astronomical Society (AAS), in Long Beach, California.
Look up at the night sky and you'll see stars, sure. But you're also seeing planets—billions and billions of them. At least. That's the conclusion of a new study by Caltech astronomers that provides yet more evidence that planetary systems are the cosmic norm.
The confirmed count of planets in other solar systems has skyrocketed to more than 850, plus thousands of identified candidates. The opportunity to characterize so many solar systems has brought together Caltech planetary scientists and astronomers, who are forming a Center for Planetary Astronomy.
