Seán Doran turns astro images into wonderful videos. We’ve seen his work before and Doran’s use of still images from organizations like NASA and JAXA to create stunning videos is incredible. Doran’s latest creation is a remastered video of the Sun.
Doran used 78,846 frames of ångström-171 data from the Solar Dynamics Observatory. He repaired, processed and rescaled the images captured during August 2014 to create the final 4K resolution video. The 48-minute timelapse showcases the Sun’s movement during that month.
It’s one thing to view still images from the Solar Dynamics Observatory, but seeing them in motion is especially impactful.
The NASA Solar Dynamics Observatory (SDO) is NASA’s first mission launched for NASA’s Living with a Star (LWS) Program. The program is designed to help us understand what causes solar variability and how it impacts Earth. The SDO is designed to further our understanding of the Sun’s effect on Earth and Near-Earth space. Some of the SDO’s goals include understanding how the Sun’s magnetic field is generated and structured and how the stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles and variance in solar irradiance. SDO launched on February 11, 2010 from Cape Canaveral in Florida.
SDO includes three instruments to capture different wavelengths of light. The instruments include the Helioseismic and Magnetic Imager (HMI), Extreme Ultraviolet Variability Experiment (EVE) and the Atmospheric Imaging Assembly (AIA). The lattermost instrument is what captured the source images that Doran used for the above video.
The video below illustrates the wide range of wavelengths that SDO can observe. It’s amazing to see the different ways instruments aboard the SDO can view the Sun.
