Recently, the James Webb Space Telescope had a close look at a phenomenon known as gravitational arcs. What are gravitational arcs? They are a type of cosmic phenomenon that occurs when the gravity of a massive object, such as a galaxy or a black hole, warps the light from an even more distant object into a distinctive curved shape. The arcs are a way for astronomers to look at the distant universe in a new way. By studying these arcs, astronomers can learn more about how galaxies and other objects interact with each other, and gain a better understanding of the structure of the universe.
