Earth’s radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA’s Van Allen Probes mission show that the fastest, most energetic electrons in the inner radiation belt are not present as much of the time as previously thought.
Magnetic explosions happen constantly all across the universe, and new results with NASA’s ARTEMIS mission help explain how near-Earth explosions convert energy into heat and propel particles toward Earth.
Scientists have proven that the warning signs of one type of space weather event can be detected up to 17 minutes before it arrives at Earth — critical time that could help protect astronauts in space.
The first images from the Solar Ultraviolet Imager or SUVI instrument aboard NOAA’s GOES-16 satellite have been successful, capturing a large coronal hole on Jan. 29, 2017.
