The gold images show the sun at a wavelength of 171 Angstroms, which corresponds to a temperature of 1 million degrees F (600,000 C). Teal images (131 Angstroms) show features 18 times hotter. The blast triggers waves that traverse the sun at 1 million mph. Credit: NASA/SDO; NASA's Goddard Space Flight Center
