Latest Solar Dynamics Observatory Stories
The sun ushered out 2013 and welcomed 2014 with two mid-level flares on Dec. 31, 2013 and Jan. 1, 2014.
A new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.
On Thanksgiving Day, Nov. 28, 2013, Comet ISON will finally sling shot around the sun. Here its inward journey through the solar system will end -- either because it will break up due to intense heat and gravity of the sun, or because, still intact, it speeds back away, never to return.
A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion.
NASA will conduct a sounding rocket launch at 2 p.m. EDT, Monday, Oct. 21, 2013, from the White Sands Missile Range in New Mexico carrying an experiment to support the calibration of the EUV Variability Experiment, or EVE, aboard the Solar Dynamics Observatory, or SDO, satellite.
NASA's Goddard Space Flight Center Visitor Center in Greenbelt, Md. will host this month's Sunday Experiment on Sunday, Sept. 15 from 1 to 3 p.m. EDT.
NASA's Solar Dynamics Observatory has helped scientists figure out a little more about what is going on inside the sun.
A new video posted by the European Space Agency (ESA) shows two solar eruptions taking place side-by-side.
- Stoppage; cessation (of labor).
- A standing still or idling (of mills, factories, etc.).
