This is an image of a solar flare captured by NASA's Solar Dynamics Observatory. It shows a solar flare in three wavelengths of light: visible, 171 angstroms, and 304 angstroms (an angstrom is roughly the diameter of an atom and it's the measurement we use to define the size of light waves). Each wavelength shows a different temperature of material. Image courtesy of Photographs Relating to Disasters and Emergency Management Programs, Activities, and Officials
