Hinode XRT, SDO AIA and NuSTAR observe the Quiet Sun

The Hinode X-ray Telescope (XRT) provides content images of 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 XRT. 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.
