Researchers at the California Institute of Technology (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—stretching over as much as a third of the planet.

If you could lick the surface of Jupiter's icy moon Europa, you would actually be sampling a bit of the ocean beneath. So says Mike Brown, an astronomer at Caltech. Brown and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that water from the vast liquid ocean beneath Europa's frozen exterior actually makes its way to the surface.

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 astronomers at the California Institute of Technology (Caltech) that provides yet more evidence that planetary systems are the cosmic norm. The team made their estimate while analyzing planets orbiting a star called Kepler-32—planets that are representative, they say, of the vast majority in the galaxy and thus serve as a perfect case study for understanding how most planets form.

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.
