Video of the day: three-year life of the Sun

About the Author


Solar Dynamics Observatory (SDO) in the last three years did not take her “eye” with the Sun, which is located almost in the middle of an eleven-year cycle. The agency NASA continues to make high-quality video. Not so long ago, the attention of users provided video “Earth at a distance of more than 160 million kilometers” and “Moon Bird’s Eye” . Currently, NASA experts took some amazing photos and combined them in a video lasting about three minutes, which you can see a gradual increase in solar activity.

Space Observatory SDO was launched February 11, 2010 under the “Life of a Star.” It was then SDO took the first shot and has since photographed the sun once every 12 seconds. On board the observatory has three large tool capable of getting 12 different types of images of the Sun. Most elegantly Sun looks at the wavelength of 171 Angstroms. Despite the fact that the SDO takes snapshots every 12 seconds to create a video, scientists took two photos of each day for three years.

Video is different frequency 29.7 frames per second. Thus, these three minutes is enough to see each full rotation of the sun (about the axis), which takes about 25 days, as well as features such as a partial eclipse, flash, and even a comet Lovejoy.
Provided SDO images provide scientists a continuous stream of information for the analysis and explanation of the various phenomena. Solar Dynamics Observatory is designed for 5 years of stable work.
