"In other words, our viewing angle makes it appear that there is more material in these two crescents than there actually may be," NASA wrote in its press release about the new photo. And they may create somewhat of an optical illusion. NASA believes the crescents, shown in the image above, are the outer layers of gas that propelled out during the supernova explosion.

Arendt (NASA’s Goddard Spaceflight Center & University of Maryland, Baltimore County), C. ![]() The parts of the supernova remnant as captured by the James Webb Space Telescope in 2023. Webb has also revealed new crescent-like structures within the remnant that Hubble didn't notice. What Hubble missed, though, is a faint outer ring with more of these bright hotspots surrounding the entire cloud of the Supernova 1987A remnant. The pearl-like ring of bubbles of light surrounding the supernova's center is called its "equatorial ring." Those hotspots formed when the supernova's shockwave slammed into the equatorial ring of gas the star had ejected tens of thousands of years before it exploded, NASA said. Webb spotted 2 features in the supernova that Hubble missed They could offer clues as to how the supernova has evolved over time. It will explore every phase of cosmic history from within our solar system to the most distant observable galaxies in the early universe, and everything in between. The Webb Space Telescope is an international partnership with the European and Canadian space agencies. Thanks to the new image's unprecedented resolution, Webb has revealed a couple of features in the supernova remnant that astronomers couldn't previously see. Fueling operations will begin Thursday, Nov.
