A NASA mission to touch the sun has revealed answers about the closest star's solar winds, which cause the aurora borealis and can affect Earth's communications systems. The Parker Solar Probe has captured information about the solar wind that flows from the sun's coronal holes toward's our ...
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 ...
patchy structure on the Sun that solar physicists call “moss.” It forms low in the solar atmosphere around the center of sunspot groups on the Sun where magnetic activity is strong. An image from NASA’s Interface Region Imaging Spectrograph, or IRIS, mission ...
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...
Like many sounding rocket missions, EUNIS’s data will be used to inform and improve other space science missions. NASA’s Solar Dynamics Observatory, or SDO, satellite images the Sun in several different bands of wavelengths. Since different wavelengths correspond to different temperatures, the more...
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 ...
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 fields an...

(Image credit: Solar Dynamics Observatory, NASA) Don't be alarmed, but the sun is constantly exploding. While violent nuclear fusion reactions power the sun's 27-million-degree-Fahrenheit (15 million degrees Celsius) core, towers of molten plasma, crackling radiation and electromagnetic energy ri...
Closer view of the equatorial region of the Sun on March 24, 2007 from the STEREO mission. (Image credit: NASA) Scientists unveiled today some of the first 3-D images of the violent electrical storms that rage within the Sun's atmosphere. In the new images, the electrified loops and ...
