Yes. I am geeking out.

To help you appreciate the sheer awesomeness of the following video, consider just how large the Sun is compared to our humble earth. Do note this image only compares the sizes of the Earth and the Sun, it does not depict how close the Earth is to the Sun. If we were actually this close to the sun our popcorn would be popping whether we wanted it to or not.

If the Sun were hollow, it would take approximately 1,000,000 Earths to fill the Sun!

This extraordinary video looks back on the 3rd year of operation of NASA’s Solar Dynamics Observatory. Since its launch in 2010, SDO’s data and imagery have exceeded everyone’s hopes and expectations, providing stunningly detailed views of the sun. The observatory has continued to return breathtaking pictures and movies of eruptive events on the sun. These images are more than just pretty. By highlighting different wavelengths of light, scientists can track how material on the sun moves. Such movement, in turn, holds clues as to what causes these giant explosions.

SDO is the first mission in a NASA’s Living With a Star program, the goal of which is to develop the scientific understanding necessary to address those aspects of the sun-Earth system that directly affect our lives and society.
