Small crescent-like structures come into clear view. NASA’s James Webb Space Telescope has uncovered new details in Supernova 1987A with its NIRCam (Near-Infrared Camera) instrument. Structures, some only visible in infrared wavelengths, provide clues into the development of supernovas over time.

Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987.
by NASA’s Hubble and Spitzer Space Telescopes and Chandra X-ray Observatory, the unparalleled sensitivity and spatial resolution of Webb revealed a new feature in this supernova remnant – small crescent-like structures. These crescents are thought to be a part of the outer layers of gas shot out from the supernova explosion. Their brightness may be an indication of limb brightening, an optical phenomenon that results from viewing the expanding material in three dimensions.
