Everyone knows you're not supposed to stare directly at the sun. But NASA has a few ways around that.
This video shows the results of different ways that scientists look at the sun.
This video is based on data from NASA's Solar Dynamics Observatory. It shows the range of wavelengths – invisible to the naked eye – that the telescope can view.
The observatory converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.
A few notes about the colors of the sun from the NASA description of the video:
Yellow light of 5800 Angstroms, for example, generally emanates from material of about 10,000 degrees F (5700 degrees C), which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, which is typically colorized in green in SDO images, comes from atoms that are about 11 million degrees F (6,300,000 degrees C) and is a good wavelength for looking at solar flares, which can reach such high temperatures.
