Astronomers spot 'time-warped' supernovas whose light both has and hasn't reached Earth

Astronomers using the James Webb Space Telescope discovered two ancient supernovas whose light has been split by gravitational lensing, creating multiple images arriving at different times across decades. While one image from each explosion has already reached Earth, the remaining images will arrive in 1-2 years and 60 years respectively due to space-time warping effects, potentially helping resolve the mysterious "Hubble tension" regarding universe expansion rates.
