NASA’s Interface Region Imaging Spectrograph Sees the Sun on Jan 17, 2021

NASA’s Interface Region Imaging Spectrograph, or IRIS, captures images of the lower regions of the Sun’s atmosphere in ultraviolet light, along with spectra that break down how much light is visible across different wavelengths. These images, captured on Jan. 17, 2021, show an active region on the Sun, an area of intense and complex magnetic fields that is prone to explosions of light and solar material. This particular active region was targeted for IRIS observations based on model predictions that suggested that magnetic field lines from this region could be ones
