Fun With The Sun



Yes, it’s Earth Day. So we’ll follow the Sun instead. NASA’s Solar Dynamics Observatory released it’s first images and video. The spacecraft’s three instruments will likely revolutionize the study of heliophysics, much as Hubble did for astronomy.




The Helioseismic and Magnetic Imager (HMI) will study the motions and magnetic fields at the Sun’s surface to figure out what’s happening inside.

The Atmospheric Imaging Assembly (AIA) is a bunch of four telescopes will check out the corona, the outer layer of the Sun’s atmosphere. The AIA filters will observe across ten wavelength and provide 725 km resolution.

And the Extreme Ultraviolet Variability Experiment (EVE) will gauge the Sun’s energy in extreme-ultraviolet wavelengths.
