If confirmed, those galaxies are quite early, as they were in existence just 200 million years after the Big Bang. Not long after, intriguing new results suggests astronomers are blasting past that metric with possible detections up to redshift 20. One week after the James Webb Space Telescope released the first science images, astronomers detected galaxies at redshift 13, equating to about 300 million years after the Big Bang. The James Webb Space Telescope has just barely started operations, but is breaking records and performing intriguing observations in its first few weeks. A composite image captured by the James Webb Space Telescope's MIRI and NIRCam instruments reveals the odd Cartwheel galaxy in an unprecedented detail.
