Celebrating the fifth anniversary of Solar Dynamics Observatory, NASA has released a gorgeous time-lapse video of our sun, a compilation of all the footage of the sun collected over the last five years.
The imagery is an example of the kind of data that SDO provides to scientists. By watching the sun in different wavelengths – and therefore different temperatures – scientists can watch how material courses through the corona, which holds clues to what causes eruptions on the sun, what heats the sun’s atmosphere up to 1,000 times hotter than its surface, and why the sun’s magnetic fields are constantly on the move.

Watch this 4-minute video as it captures one frame every eight hours, from June 2010 to Feb. 8, 2015, showing huge sun spots grow and solar materials burst into space. It’s a time-lapse videos at its best.
