ISEE-3 comes to visit Earth

(Phys.org) —It launched in 1978. It was the first satellite to study the constant flow of solar wind streaming toward Earth from a stable orbit point between our planet and the sun known as the Lagrangian 1, or L1. Monitoring ...

Astronomers find clues to decades-long coronal heating mystery

Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University's Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona ...

Space scientists find way to monitor elusive collisions in space

(Phys.org) —Many collisions occur between asteroids and other objects in our solar system, but scientists are not always able to detect or track these impacts from Earth. The "rogue debris" created by such collisions can ...

Night-time view of Aurora

(Phys.org)—Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun ...

Could plasma jet thrusters 'kickstart' interplanetary travel?

A great offshoot from commercial space companies getting a foothold in real missions to orbit is that the old entrepreneurial space spirit seems to have been revived. People are attempting to develop and build what could ...

The mysterious case of asteroid Oljato's magnetic disturbance

(Phys.org)—Back in the 1980s, the arrival of asteroid 2201 Oljato inside the orbit of Venus heralded a flurry of magnetic activity. Now, results from ESA's Venus Express spacecraft suggest that Oljato has lost its magnetic ...

The electric atmosphere: Plasma is next NASA science target

Our day-to-day lives exist in what physicists would call an electrically neutral environment. Desks, books, chairs and bodies don't generally carry electricity and they don't stick to magnets. But life on Earth is substantially ...

Researchers complete 520-day mock mission to Mars

(AP) -- Pale but smiling, an international crew of researchers on Friday walked out of a set of windowless modules after a grueling 520-day simulation of a flight to Mars.
