Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex...
An Earth-directed coronal mass ejection (CME) on Jan. 31, 2013 was accompanied by a large prominence eruption best visible in light with a wavelength of 304 angstroms. NASA’s Solar Dynamics Observatory captured this footage...
To observe how winds move high in Earth’s atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around � but scientists have no similar technique to...
The sun unleashed a monster eruption of super-hot plasma Friday, Nov. 16, in back-to-back solar storms captured on camera by a NASA spacecraft. The giant sun eruption, called a solar prominence, occurred at 1...
Scientists and sky watchers are converging on the northeast coast of Australia, near the Great Barrier Reef, for a total eclipse of the sun.
The Aurora Borealis, known as the Northern Lights, have been visible over Scotland and large parts of northern England.
Every September and October (springtime in the Antarctic) a hole forms in the protective ozone layer over the South Pole. NOAA scientists explain why it forms, how NOAA monitors and studies ozone loss, and...
The coronal mass ejection that erupted from the sun on Oct. 4, 2012 at 11:24 p.m. EDT arrived at Earth on Oct. 8 at 12:30 a.m. EDT, as observed by instruments aboard NASA’s Advanced...
