When Monday's solar eclipse casts its shadow, Colorado-based scientists will chase it in a jet flying faster than 500 mph and aim a coffin-shaped instrument straight at the sun's corona, taking measurements that eventually ...
Making interesting predictions is one of the hallmarks of successful science. When Albert Einstein formulated his theory of general relativity, an almost immediate test involved the prediction that in a solar eclipse, light ...
Humans have been digging underground for millennia—on the Earth. It's where we extract some of our most valuable resources that have moved society forward. For example, there wouldn't have been a Bronze Age without tin ...
NASA's LRO (Lunar Reconnaissance Orbiter), which has been circling and studying the moon for 15 years, captured several images of Korea Aerospace Research Institute's Danuri lunar orbiter last month. The two spacecraft, traveling ...
A total solar eclipse has begun. Totality will last up to 4 minutes, 28 seconds in certain spots.
Eclipse mania is sweeping across North America as a breathtaking celestial event on Monday promises a rare blend of commerce, science—and celebration.
On Monday, 13 states in the U.S.—starting with Texas—will experience brief moments of nighttime darkness mid-day as the moon glides in front of the sun, blocking its rays.
Eclipse spectators staked out their spots across three countries Sunday, fervently hoping for clear skies despite forecasts calling for clouds along most of the sun-vanishing route.
Millions of spectators along a narrow corridor stretching from Mexico to the U.S. to Canada eagerly awaited Monday's celestial sensation—a total eclipse of the sun—even as forecasters called for clouds.
When a rare total solar eclipse sweeps across North America on Monday, scientists will be able to gather invaluable data on everything from the sun's atmosphere to strange animal behaviors—and even possible effects on humans.
