Switch this video to HD full screen and marvel at the incredible detail in which we can now observe the sun, our closest star. This video is filled with year four highlights from the Solar Dynamics Laboratory (SDO), and it’s incredible.

Previously, the Solar TErrestrial RElations Observatory (STEREO), and Jewel Box Sun: how SDO converts the wide range of invisible wavelengths into colorized images that our human eyes can see.

From NASA Goddard, Jewel Box Sun, a surprising video that illuminates how NASA’s Solar Dynamics Observatory (SDO) converts a wide range of invisible wavelengths into colorized images that our human eyes can see. 

As the colors sweep around the sun in the movie, viewers should note how different the same area of the sun appears. This happens because each wavelength of light represents solar material at specific temperatures. Different wavelengths convey information about different components of the sun’s surface and atmosphere, so scientists use them to paint a full picture of our constantly changing and varying star. 

There are more Solar Dynamics Observatory videos in the archives.

On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled away from the sun at over 900 miles per second.

This movie shows the ejection from a variety of viewpoints as captured by NASA’s Solar Dynamics Observatory (SDO), NASA’s Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO).

Follow this up with this video primer of how SDO, STEREO, and SOHO work together to send us these phenomenal views of the sun’s entire surface and atmosphere.


Did you catch the Solar Dynamics Observatory’s videos of Venus crossing in front of the sun

On June 5 2012, SDO collected images of the rarest predictable solar event—the transit of Venus across the face of the sun. This event lasted approximately 6 hours and happens in pairs eight years apart, which are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.

For more, YouTube user scottieM3 animated the Astronomy Picture of the Day’s images to see the entire sun as Venus passed it, and It’s Okay to Be Smart reminds us that though it looks like Venus is super close to the sun and might disappear into it, “that it’s still 108 million kilometers away.”

Launched in October 2006, STEREO (Solar TErrestrial RElations Observatory) traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO, when paired with SDO, can now give us the first complete view of the sun’s entire surface and atmosphere. 

Speaking of SDO, the Solar Dynamics Observatory team just posted two videos: one of a recent large prominence eruption and one of “darker, cooler plasma” being pulled back and forth by competing magnetic forces. They were observed above the Sun’s surface for 30 hours (Feb. 7-8, 2012).
