Hubble captured a new image of galaxy cluster MACS J0417 on September 19, 2026, and what’s interesting isn’t just the photo, but what it’s for: this cluster is so massive that its gravity curves space around it and acts as a cosmic magnifying glass, or “gravitational lens.” That means it can take light from objects far behind it and magnify it, while also splitting it into multiple copies. That’s where supernova Athena comes in, discovered by the James Webb Space Telescope in 2025. Since its light travels different paths around the cluster (some shorter, some longer), the same stellar explosion doesn’t appear just once, but several times, at different moments.…
