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.

If you ask Andy Ingersoll how Caltech has contributed to our understanding of the universe, he'll tell you, "Caltech invented planetary science!" Since the field's origins 50 years ago, Caltech has become one of the top planetary-science research centers.

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.
