On February 11th, 2010, NASA launched a new spacecraft called the Solar Dynamics Observatory [SDO], which was designed to give more knowledge and clearer images of the Sun than any other spacecraft that has been launched before for this purpose. On April 21st, 2010, the scientists of NASA ...
One 'active region' on the Sun, named AR2975, has been attracting attention. AR 2975 and AR 2976 stand out on the surface of the Sun, in this image captured on March 30, 2022, by the Solar Dynamics Observatory. Credit: NASA This tangle of magnetic...

Credit: Goddard Space Flight Center Scientific Visualisation Studio/SDO/NASA For the most part, the Sun gets plenty of attention from astronomers. Its surface, or photosphere, bristles with sunspots and erupts with powerful flares. Its outer atmosphere, or corona, shimmers with gossamer arcs mapped...
Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made ofplasmain the solar atmosphere “moss.” This moss, which was first identified in 1999 by NASA’s TRACE mission, blossoms around the center of ...
This isn’t the first time that we’ve gotten a good look at a solar flare. Plenty of astrophotographers have managed to snap some great images andvideos of the Sunthrowing a tantrum. And, with so many spacecraft and observatories focused on the Sun, NASA is able to capture some fantast...
However, such images are rare because the Sun appears much closer to Earth from a great distance, increasing the risk of damaging space camera sensors. Nonetheless, the Cassini spacecraft captured this stunning image when the Sun was behind Saturn. Cassini is a joint project of NASA and ESA ...
NASA's Solar TErrestrial RElations Observatory (STEREO) satellites have provided the first three-dimensional images of the Sun in this space wallpaper.
(Image credit: NASA) Stars like our sun form when a huge cloud of gas (mostly hydrogen and helium) grows so large that it collapses under its own weight. The pressure is so high in the center of that collapsing mass of gas that the heat reaches unimaginable levels, with temperatures so...
NASA's Perseverance rovercaptured images of Mars' moon, Phobos, traversing the sun and casting a shadow across the surface of the Red Planet in a partial solar eclipse. In the timelapse of photos taken on Feb. 8, Phobos' irregularly shaped silh...
