New NASA Timelapse Shows 3 Years of Solar Activity in 3 Minutes
The amazing video below is a product of NASA’s latest endeavor at the Solar Dynamics Observatory (SDO), and provides breathtaking and high quality data that will aide astronomers in better predicting solar activity such as solar flares and coronal mass ejections. Plus, it just looks really cool!
The SDO’s Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 Angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin. In this wavelength it is easy to see the sun’s 25-day rotation as well as how solar activity has increased over three years. – Read More
