[00:00:00]Scientists say the James Webb Space Telescope has looked farther into space than humanity ever has before, so far that it's actually looking back in time.

[00:00:12]At the edge of the observable universe, Webb discovered ancient galaxies forming only a few hundred millions years after the Big Bang. Far earlier than scientists expected, some researchers say these discoveries are forcing astronomy to rethink how the universe began. In the endless darkness beyond our world, James Webb may have uncovered secrets the cosmos kept hidden for nearly 13 billion years. This is Science to Sleep By. Thanks for watching.
