Solar storm blasts Earth

The largest solar storm since 2005 swept across the planet this week, forcing airlines to reroute flights and disrupting communications from global positioning satellites. This spontaneous blast of solar radiation may have affected power grids and high-frequency radio communications in the northern latitudes, said the U.S. Space Weather Prediction Center. A number of airlines, which route some U.S.-Asia flights over […]

Mapping the moon

Two NASA probes that spent last year orbiting the moon have returned stunning new geological maps that could help explain how it, Earth, and other planets in our solar system formed. The probes, named Ebb and Flow, flew identical orbits just miles above the moon’s surface to measure its gravity field. Slight disruptions in their paths—caused by the push and […]

Life-friendly lake on mars

NASA scientists have discovered evidence that a large freshwater lake existed on Mars billion of years ago, further strengthening the case that Earth’s neighbor once harbored life.The lake was part of a network of waterways that could have lasted thousands or even millions of years—possibly long enough for simple organisms to take hold there.Those conclusions come from an analysis of […]

Freshwater under the ocean

Vast reserves of freshwater have been discovered beneath the seabed of continental shelves off Australia, China, North America, and South Africa—a potentially valuable resource for coastal cities needing to alleviate water shortages or combat drought. The finding comes from a new analysis of seafloor water studies conducted for oil and gas exploration purposes. The total volume of these untapped reserves […]

Orbital Chaos Inevitable

It’s a little bit less certain that the inner planets— Mercury, Venus, Earth, and Mars—will still be around to die that way. “There is a one percent chance the inner solar system will go dramatically unstable during the next five billion years,” says Laughlin. The problem is a weird long-distance connection between Jupiter and Mercury. When Jupiter’s closest approach to […]
