James Webb telescope discovers powerful early galaxies.

The James Webb Space Telescope has detected a highly compact galaxy that formed soon after the Big Bang and displayed an impressive rate of star formation. The galaxy, dating to 13.3 billion years ago, has a diameter of approximately 100 light-years and forms new stars at a rate similar to that of the Milky Way. The discovery is another example of how observations by Webb are transforming our knowledge of the early universe. The orbiting infrared observatory was designed to be far more sensitive than its Hubble Space Telescope predecessor.
