Gazing Deeply Through Time
ESA/Webb, NASA & CSA, L. Bradley, A. Adamo, and the Cosmic Spring collaboration
Day 11 of the 2024 Space Telescope Advent Calendar: gazing deeply through time. Using the James Webb Space Telescope, an international team of astronomers detected five young massive star clusters in the Cosmic Gems arc (SPT0615-JD1), a strongly lensed galaxy emitting light from when the universe was roughly 460 million years old—looking back across 97 percent of cosmic time.
