Solar Golden Arches

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by NASA's Solar Dynamics Observatory on April 24-26, 2017.

SDO Witnesses A Double Eclipse

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 Peers Into Huge Coronal Hole

This imagery of the sun captured by NASA's Solar Dynamics Observatory from May 17-19, 2016, shows a giant dark area on the star's upper half, known as a coronal hole.

Towering Magnetic Arches On The Sun

Arches of magnetic field lines towered over the sun's edge as a pair of active regions began to rotate into view in this video captured by NASA's Solar Dynamics Observatory on April 5-6, 2016.

SDO Sees An Unraveling Solar Prominence

An elongated solar prominence rose up above the sun's surface and slowly unraveled on Feb. 3, 2016, as seen in this video by NASA's Solar Dynamics Observatory, or SDO.

SDO Sees a Dark Filament Circle On The Sun

A dark, almost circular filament broke away from the sun in a gauzy, feathery swirl, on Nov. 15, 2015, in this video from NASA's Solar Dynamics Observatory.

An enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists Jonathan Squire and Amitava Bhattacharjee at the U.S. Department of Energy's Princeton Plasma Physics Laborator have found a clue to the answer in the collective behavior of small magnetic disturbances.

SDO Captures Image of Mid-class Solar Flare

The sun emitted a mid-level solar flare, peaking at 10:58 a.m. EDT on Sept. 28, 2015.

SDO Sees The Sun's Two Coronal Holes

NASA's Solar Dynamics Observatory, or SDO, captured this solar image on March 16, 2015, which clearly shows two dark patches, known as coronal holes.

SDO Sees Giant Filament on the Sun

A dark line snaked across the lower half of the sun on Feb.10, 2015, as seen in this image from NASA's Solar Dynamics Observatory, or SDO.

Coronal Loops Reveal Magnetic Dance

Magnetic Dance: Solar material traces out giant magnetic fields soaring through the sun to create what's called coronal loops.

SDO Collects Its 100-Millionth Image

On Jan. 19, 2015, at 12:49 p.m. EST, an instrument on NASA's Solar Dynamics Observatory captured its 100 millionth image of the sun.

First Notable Solar Flare of 2015

The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015.

The sun emitted a mid-level solar flare, peaking at 12:48 p.m. EST on Nov. 16, 2014.

SDO Sees a Mid-Level Solar Flare

The sun emitted a mid-level solar flare, peaking at 5:40 p.m. EST on Nov. 3, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.

NASA's Solar Dynamics Observatory, or SDO, which watches the sun 24 hours a day, has observed this gigantic filament for several days as it rotated around with the sun.

On Sept. 30, 2014, a sounding rocket will fly up into the sky - past Earth's atmosphere that obscures certain wavelengths of light from the sun -- for a 15-minute journey to study what heats up the sun's atmosphere. This is the fourth flight for the Very high Angular Resolution Ultraviolet Telescope, or VAULT, will launch from the White Sands Missile Range near Las Cruces, New Mexico.

On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT.

On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA's Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit.
