A solar eruption on Sept. 26, 2014, seen by NASA's Solar Dynamics Observatory affecting the ionosphere in all of Earth's northern latitudes. If erupted solar material reaches Earth, it can deplete the electrons in the upper atmosphere in some locations...
(NASA/Goddard Space Flight Center) The sun emitted a trio of mid-level solar flares on April 2-3, 2017. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events.
The sun emitted a trio of mid-level solar flares on April 2-3, 2017. The first peaked at 4:02 a.m. EDT on April 2, the second peaked at 4:33 p.m. EDT on April 2, and the third peaked at 10:29 a.m. EDT on April 3. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events. Show More Summary
The Solar Dynamics Observatory (SDO) has now captured nearly seven years worth of ultra-high resolution solar footage. This time lapse shows that full run from two of SDO's instruments. The large orange sun is visible light captured by HMI. The...
It seems like only yesterday that I was noting First Light on Nasa’s Solar Dynamics Observatory [SDO], and the early hours of this morning for ‘three years in three minutes‘ and ‘SDO Year 4‘. In fact the SDO was launched on 11 Feb 2010, with First Light in April of that year. [Seven long years… more...
Astronomers from the University of Hawaii Institute for Astronomy (IfA), Brazil, and Stanford University may have solved a long-standing solar mystery. Two decades ago, scientists discovered that the outer five percent of the sun spins more slowly than the rest...
NASA's Solar Dynamics Observatory just spotted a massive hole on the sun surface called a coronal hole. The hole appears black because it's cooler than its surroundings, and is responsible for high-speed solar winds that can sometimes...Show More Summary
On Oct. 19, 2016, operators instructed NASA's Solar Dynamics Observatory, or SDO, to look up and down and then side to side over the course of six hours, as if tracing a great plus sign in space. During this time, SDO produced some unusual data. Show More Summary
A few hours before the Halloween night, NASA's Solar Dynamics Observatory, or SDO caught an image of a partial solar eclipse and what looks like a rather frightened sun. The blazing body appears to shudder as the moon crosses its path. Show More Summary
NASA combined two pictures of the sun at different wavelengths of extreme ultraviolet light to create a spooky Halloween image.
Massive arches of solar material brighten and stream over an active region on the sun's surface in this animation of imagery captured by NASA's Solar Dynamics Observatory, or SDO, on Sept. 29, 2016.
On Sept. 1, the SDO captured a rare sight.
Early in the morning of Sept. 1, 2016, NASA's Solar Dynamics Observatory, or SDO, caught both Earth and the moon crossing in front of the sun. SDO keeps a constant eye on the sun, but during SDO's semiannual eclipse seasons, Earth briefly blocks SDO's line of sight each day -- a consequence of SDO's geosynchronous orbit.
After more than a week offline, NASA’s Solar Dynamics Observatory — the sun-watching spacecraft responsible for these close-up images of solar flares, fire and loops — is back. But just what caused it to glitch in the first place? More »

Beautiful bursts on the solar surface, invisible to the human eye, have been recorded in high-resolution video by NASA’s Solar Dynamics Observatory at the early-July peak of the sun’s activity this year.
For seven hours on July 6, NASA's Solar Dynamics Observatory (SDO) did a 360 degree spin, on one axis, through space. By taking images every 12 seconds and then colorizing the ultraviolet wavelengths of the photo in gold, NASA created...Show More Summary
Space acrobatics is all part of the job for NASA’s Solar Dynamics Observatory.
No, the space-based Solar Dynamics Observatory isn’t on the fritz—it was actually instructed to make this flip while snapping pics of the Sun. It might sound like NASA took this thing out for a joy ride, but there’s a very good reason for the evasive maneuver. Read more...
