Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed sunlight to split water molecules, producing energy to power their cells and releasing oxygen into an atmosphere that had previously had none. These early environmental engineers are responsible for the life we see around us today, and much more besides. At 8:00 p.m. on Wednesday, November 19, in Caltech's Beckman Auditorium, Professor of Geobiology Woodward "Woody" Fischer will describe how they transformed the planet. Admission is free.

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.

Andrew Ingersoll's research has included studies of the so-called runaway greenhouse effect that is thought to have boiled away Venus's oceans, the presence of liquid water on Mars, and the atmospheric dynamics of Jupiter, Saturn, Uranus, and Neptune.

An ankle- or hip-deep stream once flowed with force across the surface of Mars in the very spot where the Curiosity rover is currently exploring. The finding provides new information about a once wet environment in Gale Crater.

Several hypotheses have been proposed to explan how clay minerals detected on the surface of Mars were formed. Now, publishing in the journal Nature Geoscience, a team of French and American scientists including Caltech's Bethany Ehlmann, has suggested a new possibility. The Los Angeles Times recently spoke to Ehlmann about the paper and its implications.

Since Curiosity touched down safely on Mars, most of her time has been taken up by a series of checkouts, but she has relayed hundreds of images back to Earth, giving the science team plenty to study and discuss.

The mood at JPL late Sunday night was overwhelmingly, almost deliriously, celebratory. The Mars Science Laboratory rover, Curiosity, touched down safely on Mars and minutes later relayed its first images back to Earth.
