Astronomers have obtained their most detailed look yet at young galaxies in the early universe using the James Webb Space Telescope, Hubble Space Telescope and Atacama Large Millimeter/submillimeter Array. The conclusion? These cosmic adolescents grew up incredibly fast.
The team behind this research observed 18 galaxies located around 12.5 billion light-years away over a range of wavelengths of light. Existing just over 1 billion years after the Big Bang, these galaxies were in the midst of rapid star formation and were therefore undergoing explosive growth.
