NASA's MMS Captures Magnetic Reconnection in Action
Like sending sensors up into a hurricane, NASA has flown four spacecraft through an invisible maelstrom in space, called magnetic reconnection. Magnetic reconnection is one of the prime drivers of space radiation and so it is a key...

NASA | First Sightings of How a CME Forms
On July 18, 2012, a fairly small explosion of light burst off the lower right limb of the sun. Such flares often come with an associated eruption of solar material, known as a coronal mass ejection or CME -- but this one did not....

How NASA Will Protect Astronauts From Space Radiation
August 1972, as NASA scientist Ian Richardson remembers it, was hot. In Surrey, England, where he grew up, the fields were brown and dry, and people tried to stay out of the Sun, indoors and televisions on. But for several days that...
