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.

For the past three years, astronomers at the California Institute of Technology's Palomar Observatory in Southern California have been using the High Performance Wireless Research and Education Network (HPWREN) as the data transfer cyberinfrastructure to further our understanding of the universe. Recent applications include the study of some of the most cataclysmic explosions in the universe, the hunt for extrasolar planets, and the discovery of our solar system's tenth planet. The data for all this research is transferred via HPWREN from the remote mountain observatory to college campuses hundreds of miles away.

To paraphrase a certain young lady from literature, the tenth planet Xena is getting curiouser and curiouser. Data released today by the Space Telescope Science Institute reveals that Xena is about 5 percent larger than Pluto, which means that it must be the most reflective planet in the solar system.

In the not-too-distant past, the planet Pluto was thought to be an odd bird in the outer reaches of the solar system because it has a moon, Charon, that was formed much like Earth's own moon was formed. But Pluto is getting a lot of company these days. Of the four largest objects in the Kuiper belt, three have one or more moons.
