Webb Reveals Complex Galactic Structures
This image from the NASA/ESA/CSA James Webb Space Telescope shows IC 5332, a spiral galaxy, in unprecedented detail thanks to observations from the Mid-InfraRed Instrument (MIRI). Its symmetrical spiral arms, which appear so clearly in Hubble’s ultraviolet and visible-light image of IC 5332, are revealed as a complex web of gas, emitting infrared light at a variety of temperatures. Capturing light at these wavelengths requires very specialised instruments kept at very cold temperatures, and MIRI performs spectacularly at the task.
