Inside a Solar Eruption: NASA's SDO Provides First Sightings of How a Coronal Mass Ejection Forms
February 1, 2013 — 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 ... > full story -
Space Instrument Adds Big Piece to Solar Corona Puzzle
January 23, 2013 — How can the solar atmosphere get hotter, rather than colder, the farther you go from the sun's surface? This mystery has puzzled solar astronomers for decades. A suborbital rocket mission that ... > full story -

Cluster Mission Indicates Turbulent Eddies May Warm the Solar Wind
January 8, 2013 — The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind -- and this wind is hotter than it should be. A new study of data obtained by ... > full story -
'Gusty Winds' in Space Turbulence: First Direct Measurement of Its Kind in the Lab
December 17, 2012 — Imagine riding in an airplane as the plane is jolted back and forth by gusts of wind that you can't prove exist but are there nonetheless. Similar turbulence exists in space, and a research team has ... > full story -
How White Dwarfs Mimic Black Holes
December 17, 2012 — Astronomers have revealed that bright X-ray flares in nearby galaxies, once assumed to indicate the presence of black holes, can in fact be produced by white dwarfs. They made the discovery by ... > full story -
