NASA’s Hubble Telescope Reaches Milestone, Looks for Elusive Supernova

NASA’s Hubble Space Telescope captured this image of massive galaxy cluster MACS J0417 (left of center) on Sept. 19, 2026. This galaxy cluster acts as a gravitational lens, bending and magnifying light from objects far behind it. Supernova Athena, discovered by NASA’s James Webb Space Telescope in 2025, is predicted to reappear between now and […]
