This is the first full view of the quiet Sun with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR). The high-energy X-rays from NuSTAR are shown in comparison to EUV images from NASA’s Solar Dynamics Observatory/Atmospheric Imaging Assembly instrument (SDO/AIA) and the X-ray Telescope (XRT) on JAXA’s Hinode. These three telescopes all captured the quiet Sun on September 28, 2018, with the NuSTAR images made from a mosaic of smaller images.
This video highlights a variety of bright points and structures even though the Sun is nearing the minimum of its activity cycle, without any active regions or flares present. NuSTAR gives a unique view of the energetic processes that are present on the quiet Sun, helping to understand how the atmosphere of the Sun is heated.
The Nuclear Spectroscopic Telescope Array science operations center is located on the campus of the California Institute of Technology
