What's Wrong with the Sun?

The sun is entering its 3rd year of eerie calm. Sunspots are rare and solar flares simply aren't happening. Is this "solar minimum" lasting longer than it should? A NASA scientist has examined centuries of sunspot data to find the answer.

A Telescope Made of Moondust

Mix moondust with epoxy, add a dash of carbon nanotubes, and spin. The result? A parabolic mirror perfectly suited for a lunar observatory. A NASA scientist has discovered this new recipe for making telescopes out of moondust, and to prove it works he has spun a "moondust mirror" here on Earth.

NASA to Attempt Historic Solar Sail Deployment

This summer, NASA engineers will try to realize a dream older than the Space Age itself: the deployment of a working solar sail in Earth orbit. The name of the device is NanoSail-D and it is scheduled for launch onboard a SpaceX Falcon 1 rocket as early as July 29, 2008.

Apollo Relic Reveals its Secrets

In 1967, Surveyor 3 landed on the Moon. Two years later, Apollo astronauts visited the little unmanned spacecraft and brought pieces of it home to Earth. Now, a portion of Surveyor's robotic arm, the scoop it used to sample moondust, is teaching researchers some long-lost secrets.

Strange Ring Found Circling Dead Star

NASA's Spitzer Space Telescope has found a bizarre ring of material around the magnetic remains of a star that blasted itself to smithereens. Although rings and spheres of material are common in the universe, this one is not like any ring astronomers have ever seen before.

Cartwheel Coronal Mass Ejection

Imagine a billion-ton cloud of gas launching itself off the surface of the sun and then ... doing a cartwheel. That's exactly what happened on April 9, 2008, when a coronal mass ejection or "CME" pirouetted over the sun's limb in full view of an international fleet of spacecraft.

Lunar GRAIL

Gravitationally speaking, the moon is a strange place. Satellites in lunar orbit feel odd, sideways tugs and end up nose down in the moondust. Astronauts standing in the middle of lunar lava seas weigh more than they do standing on the shore. A new NASA mission named GRAIL aims to map the moon's quirky gravity field and thus pave the way for future exploration.
