If you follow science news, you've heard a lot about something called dark energy, and you're probably feeling lost and confused. What is it? Is it important? Could it affect Superman, who is normally only vulnerable to Kryptonite or magic?

In 2006, NASA gravity and subsurface radar maps revealed a 500-kilometer-wide crater that lies hidden more than a mile beneath the East Antarctic Ice Sheet, created by a 50-kilometer wide object. The gravity measurements suggest that it could date back about 250 million years -- the time of the Permian-Triassic extinction, when almost all animal life on Earth died out.

We seem to be inside a "local bubble" in a network of cavities in the interstellar medium, probably carved by massive star explosions millions of years ago. The interstellar medium (or ISM) is the matter that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, dust, and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space.

Sitting like a bead on a cosmic thread, Australian astronomers have identified our galaxy's position in the large scale structure of the cosmos. Dr Stefan Keller from the Research School of Astronomy and Astrophysics at the Australian National University and colleagues made the discovery while studying ancient balls of tightly packed stars called globular clusters.

In the Hollywood blockbuster "Speed," a bomb on a bus is rigged to blow up if the bus slows down below 50 miles per hour. The premise -- slow down and you explode -- makes for a great action movie plot, and also happens to have a cosmic equivalent.
