The Ring Nebula, whose iconic shape and large size make it a favorite of amateur astronomers, can now be seen in new detail, after NASA's Hubble Space Telescope captured a sharp image of the nebula.

At nearly seven miles below the water's surface, the Mariana Trench is the deepest spot in Earth's oceans. And the site north of Guam is where director and explorer James Cameron recently fulfilled a longtime goal of reaching the bottom in a manned craft.

For the dive, Cameron designed a 24-foot submersible vehicle, the Deepsea Challenger — "this kind of long, green torpedo that moves vertically through the water," as he tells All Things Considered's Melissa Block. Cameron was able to watch his descent, he says, through a window that was about 9-1/2 inches thick.

Discovered during a training exercise in the ocean near San Diego, the torpedo will eventually make its way to a museum.

The bottlenose dolphins were honing their ability to find underwater mines when the discovery was made. The torpedo did not have a warhead, Navy officials say.
