The James Webb Space Telescope, performing splendidly as it examines the universe, has got astronomers scratching their heads. The very distant universe looks a little different than expected.
The telescope, launched eight months ago and orbiting the sun about a million miles from Earth, has been capturing images of extremely faint galaxies that emitted their light in the first billion years or so after the big bang. Observing these "early" galaxies is one of the main missions of the telescope - to see deeper into space, and further back in time, than any previous telescope.
