Carolyn Porco shares exciting new findings from the Cassini spacecraft's recent sweep of one of Saturn's moons, Enceladus. Samples gathered from the moon's icy geysers hint that an ocean under its surface could harbor life.
Travel across the universe (or is it universes?) to see stunning images of Saturn's rings, hear haunting sounds from distant black holes and catch an infectious sense of wonder about galaxies far, far away.
For the last 12 years, Carter Emmart has been coordinating the efforts of scientists, artists and programmers to build a complete 3D visualization of our known universe. He demos this stunning tour and explains how it's being shared with facilities around the world.
Bill Stone, a maverick cave explorer who has plumbed Earth's deepest abysses, discusses his efforts to mine lunar ice for space fuel and to build an autonomous robot for studying Jupiter's moon Europa.
Scientists at Argonne National Laboratory are using the IBM Blue Gene supercomputer to model supernovas, and New Scientist has published a gallery of snapshots from the fiery visualizations. The images uncover the beautiful symmetry -- and chaos -- flowing through these explosive events.

Worth a read: Fascinating Op/Ed piece in today's Times by Carolyn Porco on the brightening future for human space travel, which has been faltering since the Nixon era. TED2006 speaker, Burt Rutan, had a lot to say about this in his TED talk, which provocatively began: "Houston, we have a problem. We're entering a second generation of no progress...
Quotes of the day:
Cassini imaging team head Carolyn Porco: "So there are possibly liquid water, organic materials and excessive heat on Saturn and its moons. Which means that Saturn could be a place were life is possible. If we can demonstrate that Genesis has happened not once (Earth) but twice (Saturn) then we can infer that it has happened...
