Webb telescope reveals early universe's compact galaxy secrets.

The James Webb Space Telescope has detected a highly compact galaxy that formed 13.3 billion years ago, just 510 million years after the Big Bang. The galaxy has a diameter of approximately 100 light-years and forms new stars at a rate similar to that of the Milky Way. The discovery challenges current understanding of galaxy formation in the early universe and highlights the power of the James Webb Space Telescope, which is far more sensitive than its predecessor, the Hubble Space Telescope. The galaxy was observed using gravitational lensing, which magnified the light traveling from the distant galaxy.
