The Webb telescope shows tantalizing views of the early universe

Just over a year after its historic launch, NASA James Webb Space Telescope JWST challenges astronomers’ predictions of the early universe and shows that massive galaxies likely formed much earlier than expected.

JWST sees in the run Infrared part of the electromagnetic spectrum invisible to our eyes, according to NASA. This means that the telescope is optimized for catching light from the early universe, which was stretched toward these longer, redder wavelengths as the universe expanded over time – a process known as redshift.
