SDO Views Our Sun In Three Different Wavelengths
From March 20-23, 2018, NASA’s Solar Dynamics Observatory captured three sequences of our Sun in three different extreme ultraviolet wavelengths. The resulting images illustrate how…
NASA Satellites Recreate Solar CME Eruption in 3D
The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the…
Astronomers Reveal How a Magnetic Cage Stopped a Solar Eruption
A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights…
NASA’s Solar Dynamics Observatory Views Total Solar Eclipse
On Sunday, February 11, 2018, NASA’s Solar Dynamics Observatory, or SDO, saw a total solar eclipse in space when Earth crossed its view of the…
NASA’s Solar Dynamics Observatory Detects Solar Flare Pulses at Sun and Earth
When our Sun erupts with giant explosions — such as bursts of radiation called solar flares — we know they can affect space throughout the…
NASA’s Solar Dynamics Observatory Views Rare Encircling Filament
NASA’s Solar Dynamics Observatory (SDO) came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (October 29-31,…
From Hot to Hottest, SDO Shows the Sun from Its Surface to Its Upper Atmosphere
This sequence of images from the Solar Dynamics Observatory shows the Sun from its surface to its upper atmosphere all taken at about the same…
NASA’s Solar Dynamics Observatory Spots a Lunar Transit
NASA’s Solar Dynamics Observatory captured a new image of a lunar transit when the Moon crossed the spacecraft’s view of the Sun. On October 19,…
Solar Dynamics Observatory Captures Image of Mid-level Flare
NASA’s Solar Dynamics Observatory captured an image of a mid-level solar flare emitted from the sun on September 4th. The sun emitted a mid-level solar…
Astronomers Detail the Nature of Solar Brightness Variations
For the first time, researchers reconstruct and detail the two phenomena that are responsible for the fluctuation of brightness in our sun. The Sun shines…
Scientists Watch the Sun Stop Its Own Solar Eruption
A team of astronomers watch as a failed solar eruption occurs on the surface of the Sun, leaving astronomers with a wealth of data captured…
Solar Dynamics Observatory Tracks an Active Region on the Sun
NASA’s Solar Dynamics Observatory (SDO) watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun…
NASA’s SDO Watches a Sunspot That is Larger Than Earth
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…
NASA’s Solar Dynamics Observatory Sees Partial Solar Eclipse in Space
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…
NASA’s Solar Dynamics Observatory Views a Trio of Solar Flares
NASA’s Solar Dynamics Observatory captured the new images of the three solar flares. The sun emitted a trio of mid-level solar flares on April 2-3,…
NASA’s Solar Dynamics Observatory Views a Spotless Sun
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…
NASA’s Solar Dynamics Observatory Captures a Partial Solar Eclipse
NASA’s Solar Dynamics Observatory experienced a partial solar eclipse in space when it caught the moon passing in front of the sun. The moon’s shadow…
