NASA’s Solar Dynamics Observatory (SDO) watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun…
Using data from the Solar and Heliospheric Observatory, or SOHO, astronomers have detected a type of wave called g-modes on the Sun. After four decades…
Astronomers may now be able to explain why the Sun’s magnetic field reverses every eleven years. New research explains how the duration of the magnetic…
NASA’s Solar Dynamics Observatory observes a sunspot that is the first to appear after the sun was spotless for two days. The dark core of…
Our sun is heading toward solar minimum. Sunspot counts were relatively high in 2014, and now they are sliding toward a low point expected in…
For the first time, a computer simulation shows how solar material burst from the sun’s surface form, helping astronomers understand how these spicules can break…
NASA’s Solar Dynamics Observatory (SDO) saw a partial solar eclipse in space when it caught the moon passing in front of the sun on May…
Using data from the the high-precision science instrument CLASP (Chromospheric Lyman-Alpha Spectro-Polarimeter), scientists reveal the first-ever polarization measurements of ultraviolet light emitted from the sun’s…
NASA’s Solar Probe Plus will enter the sun’s corona and measure the full force of supersonic solar particles and radiation with a Faraday cup developed…
For a 15 day stretch beginning on March 7, 2017, NASA’s Solar Dynamics Observatory returned visible light images of a yolk-like spotless sun. This is…
New research from NASA’s Fermi Gamma-ray Space Telescope reveals high-energy light from solar eruptions located on the far side of the sun, which should block…
New images taken with the Atacama Large Millimeter/submillimeter Array have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted…
This new image from NASA’s Solar Dynamics Observatory shows a coronal hole in our sun. This imagery of the sun captured by NASA’s Solar Dynamics…
Using the Karl G. Jansky Very Large Array Radio Telescope, along with other telescopes at ultraviolet and X-ray wavelengths, astronomers reveal new insights into solar…
This short video from NASA’s Solar Dynamics Observatory shows arches of bundled magnetic loops sprouting from active regions on the Sun. Two active regions sprouted…
This short video from NASA’s Solar Dynamics Observatory shows a dozen minor outbursts on the Sun over a 30-hour period. This close-up video by NASA’s…
This newly released image from NASA’s Solar Dynamics Observatory shows a coronal hole across the top of the sun. The dark area across the top…
