NASA on Tuesday released five images from the early work of the James Webb Space Telescope.

The pictures highlighted the great potential of the telescope to plumb the secrets of deep space. Below are some of the things we have learned so far

The Hubble Space Telescope's experience returning hazy photos to NASA shown that cutting-edge scientific instruments occasionally did not function as expected.

The Hubble was repaired by astronauts on numerous occasions, but the Webb was too far away from Earth for such repairs to be feasible.

Even further-off galaxies were visible scattered across the sky in the photograph of the distant star cluster SMACS 0723.

The gravitational field of the cluster intensified the light from those galaxies, which was then created more than 13 billion years ago.

The most ancient and remote stars may not have looked like the stars we see now, according to astronomers' theories.
