Each and every day, our Solar Dynamics Observatory satellite collects data about our brightest star☀️. Our satellite helps researchers understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
This image of the sun, taken today, combines images in three wavelengths of extreme ultraviolet light. Each different wavelength of extreme ultraviolet light present in the Sun's corona correlates to material of different temperatures, resulting sometimes in completely different views of the same Sun. Scientists examine the combined images to reveal the solar atmosphere in all its detail.
