NASA’s STORIE Mission to Tell Tale of Earth’s Ring Current

Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current. This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which […]

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us. One year ago today, representatives from NASA and about 30 other […]

NASA’s Record-Shattering, Theory-Breaking MMS Mission Turns 10

Since its launch on March 12, 2015, NASA’s MMS, or Magnetospheric Multiscale, mission has been rewriting our understanding of a key physical process that is important across the universe, from black holes to the Sun to Earth’s protective magnetic field. This process, called magnetic reconnection, occurs when magnetic field lines tangle and explosively realign, flinging […]
