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.

Results from NASA's Kepler planet-hunting mission have indicated that the most common planets in the galaxy are super-Earths—those that are bigger than Earth but smaller than Neptune. Heather Knutson and her colleagues are using space telescopes to try to find out more about these worlds.

In 1964, Caltech astronomy professor Guido Münch and Jet Propulsion Laboratory space scientists Lewis Kaplan and Hyron Spinrad pushed the world's second-largest telescope to its limits and dashed—at least for the next few decades—any hopes of finding liquid water on Mars.

Using gravity measurements collected by NASA's Cassini spacecraft, scientists have confirmed that Saturn's moon Enceladus harbors a large subsurface ocean near its south pole, fueling plumes first seen in 2005.

If you ask Andy Ingersoll how Caltech has contributed to our understanding of the universe, he will tell you, "Caltech invented planetary science!" And since the field's origins just fifty years ago, Caltech has become one of the top centers of planetary science research in the world.
