Latest Solar Dynamics Observatory Stories
On Nov. 22, 2014 from 5:29 to 6:04 p.m. EST., the moon partially obscured the view of the sun from NASA's Solar Dynamics Observatory. This phenomenon, which is called a lunar transit, could only be seen from SDO's point of view.
The sun emitted a mid-level solar flare, peaking at 12:48 p.m. EST on Nov. 16, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.
The sun emitted a mid-level solar flare, peaking at 3:01 p.m. EDT on Oct. 2, 2014. NASA's Solar Dynamics Observatory, which watches the sun 24-hours a day, captured images of the flare.
A snaking, extended filament of solar material currently lies on the front of the sun -- some 1 million miles across from end to end.
The sun emitted a mid-level solar flare, peaking at 10:58 p.m. EDT on Sept. 27, 2014, and NASA's Solar Dynamics Observatory captured images of the event.
On Sept. 10, 2014, NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS, mission joined other telescopes to witness an X-class flare – an example of one of the strongest solar flares -- on the sun.
The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event.
Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun’s activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space.
On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun.
As children, we are told never to look directly at the Sun, especially through the lens of a camera, telescope or magnifying glass. To fully understand our star, scientists must use spacecraft that can observe this invisible light before it is absorbed by the atmosphere.
