The first of a series of coronal mass ejections (CMEs) over three days (Aug. 20-22), this bulbous CME certainly resembles a light bulb. It has the thin outer edge and a bright, glowing core at its center. CMEs are often bulbous, but it has been years since we…
Ver en NASA ↗On the 8th anniversary of its launch in 2010, NASA's Solar Dynamics Observatory captured a total solar eclipse on Feb. 11, 2018 when Earth crossed in front of the sun. It lasted just 31 minutes.
Ver en NASA ↗NASA's Solar Dynamics Observatory shows a lunar transit, when the Moon partially blocked SDO's view of the Sun on Nov. 7, 2018.
Ver en NASA ↗The two most noteworthy features on the sun this week were a pair of elongated filaments, as seen by NASA's Solar Dynamics Observatory on Sept. 8, 2016.
Ver en NASA ↗Artist concept of NASA STEREO-A Spacecraft Observing a very active Sun.
Ver en NASA ↗NASA's Solar Dynamics Observatory shows that the Sun has gone an entire month without any sunspots (Feb. 1-18, 2019).
Ver en NASA ↗NASA's Solar Dynamics Observatory shows that a solar prominence rose up above the Sun's surface, twisted and spun around, then became elongated and broke away. (Oct. 24-25, 2018).
Ver en NASA ↗NASA's Solar Dynamics Observatory SDO saw both the Moon upper right and the Earth upper left partially block the sun Sept. 1, 2016 at 7:33 UT. Just before this image was taken, the Earth totally blocked the sun for a while.
Ver en NASA ↗An artist concept illustrates the positions of the Voyager spacecraft in relation to structures formed around our Sun by the solar wind.
Ver en NASA ↗This artist concept shows how NASA Voyager 1 spacecraft is bathed in solar wind from the southern hemisphere flowing northward. This phenomenon creates a layer of giant bubble of solar ions just inside the outer boundary of the heliosphere.
Ver en NASA ↗The sun emitted a solar flare on Dec. 4, 2014, seen as the flash of light in this image from NASA's Solar Dynamics Observatory. The image blends two wavelengths of extreme ultraviolet light – 131 and 171 Angstroms – which are typically colored in teal and gol…
Ver en NASA ↗On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly…
Ver en NASA ↗NASA's Solar Dynamics Observatory observed a small prominence rose up above the sun, appeared to twist around for several hours, and then began to send some streams of plasma back into the sun (Jan. 3-4, 2018).
Ver en NASA ↗Three substantial coronal holes rotated across the face of the Sun the week of Sept. 8-10, 2015 as seen by NASA Solar Dynamics Observatory. Coronal holes are areas where the Sun magnetic field is open and a source of streaming solar wind.
Ver en NASA ↗Several small sunspots appeared this week, giving NASA's Solar Dynamics Observatory a chance to illustrate their sources Mar. 2, 2017. Magnetic forces are the dynamic drivers here in these regions of the sun.
Ver en NASA ↗The Sun's glint radiates off the Atlantic Ocean as the International Space Station orbited 253 miles above the African nation of Mauritania.
Ver en NASA ↗This side-by-side rendering of the Sun at the same time in two different wavelengths of extreme ultraviolet light helps to visualize the differing features visible in each wavelength Dec. 10-11, 2015. This image is from NASA Solar Dynamics Observatory
Ver en NASA ↗The sun descends to the Martian horizon and sets in this image from the panoramic camera Pancam on NASA Mars Exploration Rover Opportunity. A movie is available at the Photojournal.
Ver en NASA ↗NASA's Solar Dynamics Observatory shows a good-sized coronal hole at a slanted angle nearly centered on the face of the sun (Oct. 31 - Nov. 2, 2018).
Ver en NASA ↗NASA's Solar Dynamics Observatory is in another eclipse season as of Feb. 6, 2019. This image shows the Earth briefly blocking SDO's view of the Sun.
Ver en NASA ↗An eruption from the surface of the sun is conspicuous in the lower left portion of this July 6, 2015, image from NASA Earth-orbiting Solar Dynamics Observatory SDO.
Ver en NASA ↗This image from NASA's Solar Dynamics Observatory shows a broad coronal hole, the dominant feature this week on the sun on Nov. 7-9, 2017. It was easily recognizable as the dark expanse across the top of the sun and extending down in each side.
