I’m not a scientist, but I love science.

(Note the audio, the sound of the “heartbeat” of the Sun.)

The surface of the sun from October 14th to 30th, 2014, showing sunspot AR 2192, the largest sunspot of the last two solar cycles (22 years). During this time sunspot AR 2191 produced six X-class and four M-class solar flares. The animation shows the sun in the ultraviolet 304 ångström wavelength, and plays at a rate of 52.5 minutes per second. It is composed of more than 17,000 images, 72 GB of data produced by the solar dynamics observatory (http://sdo.gsfc.nasa.gov/) + (http://www.helioviewer.org/). This animation has be rendered in 4K, and resized to the Youtube maximum resolution of 3840×2160. The animation has been rotated 180 degrees so that south is ‘up’. The audio is the “heartbeat” of the sun, processed from SOHO HMI data by Alexander G. Kosovichev. Image processing and animation by James Tyrwhitt-Drake.
