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.
