This year-long time-lapse of the sun reveals its incredible power

NASA's Solar Dynamics Observatory (SDO) used powerful HD cameras to film the sun for an entire year then sped up the footage to create this mesmerizing time-lapse. Zach Wasser contributed to an earlier version of this video. Follow Tech Insider: On Facebook Join the conversation about this story »

SDO sees partial eclipse in space

On May 25, 2017, NASA's Solar Dynamics Observatory, or SDO, saw a partial solar eclipse in space when it caught the moon passing in front of the sun. The lunar transit lasted almost an hour, between 2:24 and 3:17 p.m. EDT, with the moon covering about 89 percent of the sun at the peak of its journey across the sun's face. Show More Summary

Astronomers Observe Rare Blank Sun, Warn of Solar Minimum

NASA’s Solar Dynamics Observatory captured a stunning image of a rare phenomenon which some scientists say is a sure sign of the oncoming solar minimum. The solar minimum is a regularly-occurring phase of the solar cycle which marks a low point in solar activity. That means solar...

NASA captured stunning images of three simultaneous solar flares

On April 2 and 3, 2017, three solar flares erupted from the sun. NASA's Solar Dynamics Observatory captured the stunning view. Follow Tech Insider: On Facebook Join the conversation about this story »

NASA's Solar Dynamics Observatory Live-Streamed Spectacular Solar Eruption (WATCH)

A solar eruption on Sept. 26, 2014, seen by NASA's Solar Dynamics Observatory affecting the ionosphere in all of Earth's northern latitudes. If erupted solar material reaches Earth, it can deplete the electrons in the upper atmosphere in some locations...        

NASA's solar dynamics observatory captured trio of solar flares April 2-3

(NASA/Goddard Space Flight Center) The sun emitted a trio of mid-level solar flares on April 2-3, 2017. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events.

Solar Dynamics Observatory captured trio of solar flares April 2-3

The sun emitted a trio of mid-level solar flares on April 2-3, 2017. The first peaked at 4:02 a.m. EDT on April 2, the second peaked at 4:33 p.m. EDT on April 2, and the third peaked at 10:29 a.m. EDT on April 3. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events. Show More Summary

NASA --Rise & Fall of the Sun's Current Solar Cycle (WATCH Video)

The Solar Dynamics Observatory (SDO) has now captured nearly seven years worth of ultra-high resolution solar footage. This time lapse shows that full run from two of SDO's instruments. The large orange sun is visible light captured by HMI. The...        

Seven years of Solar Dynamics

5 months agoNews : Slugger O'Toole

It seems like only yesterday that I was noting First Light on Nasa’s Solar Dynamics Observatory [SDO], and the early hours of this morning for ‘three years in three minutes‘ and ‘SDO Year 4‘.  In fact the SDO was launched on 11 Feb 2010, with First Light in April of that year. [Seven long years… more...

NASA Solar Dynamics Observatory --Earth is Putting the "Brakes" On Sun's Rotation

Astronomers from the University of Hawaii Institute for Astronomy (IfA), Brazil, and Stanford University may have solved a long-standing solar mystery. Two decades ago, scientists discovered that the outer five percent of the sun spins more slowly than the rest...        

NASA just spotted a massive hole growing on the surface of the sun — here’s what it means

NASA's Solar Dynamics Observatory just spotted a massive hole on the sun surface called a coronal hole. The hole appears black because it's cooler than its surroundings, and is responsible for high-speed solar winds that can sometimes...Show More Summary

Image: NASA's SDO performs calibration maneuvers

On Oct. 19, 2016, operators instructed NASA's Solar Dynamics Observatory, or SDO, to look up and down and then side to side over the course of six hours, as if tracing a great plus sign in space. During this time, SDO produced some unusual data. Show More Summary
