For the first time, physicists have observed a mysterious process called magnetic reconnection—wherein opposing magnetic field lines join up, releasing a tremendous burst of energy. The discovery, published today in Science, may help us unlock the secrets of space weather and learn about some of the weirdest, most…
At 10:44 PM ET last night, NASA successfully launched the United Launch Alliance Atlas V rocket into space. It carries with it four Magnetospheric Multiscale spacecraft that will spend two years studying the magnetic fields between the Earth and the Sun.
