James Webb telescope marks 1 year of peering into far corners of the universe

Astronomers and fans of its stunning images of deep space are celebrating the James Webb Space Telescope's first year of operation this week.

One year ago Wednesday, the first image was unveiled ceremoniously at the White House by U.S. President Joe Biden and NASA administrator Bill Nelson.

The $10 billion US telescope is the successor to the aging Hubble Space Telescope, which was launched into orbit in 1990. Both the Hubble and Webb telescopes use a series of curved mirrors instead of lenses to reflect light that is collected by powerful sensors and instruments to produce their hypnotic images.

According to the North Americans Space Agency (NASA), the JWST has a much larger primary mirror than the Hubble, which ultimately lets it absorb more light from further away. 

"In just one year, the James Webb Space Telescope has transformed humanity's view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the very first time." Nelson said in a release accompanying the newest image from the telescope.

The image of the Rho Ophiuchi cloud complex, the closest star-forming region to Earth at some 390 light-years away, illustrates the power of the telescope.

Here are some of the highlights from the JWST releases over its first year.

The first full-colour image from the Webb telescope, a revolutionary apparatus designed to peer back through the cosmos to the dawn of the universe, shows the galaxy cluster SMACS 0723, known as Webb's First Deep Field, in a composite made from images at different wavelengths taken with a near-infrared camera and released July 11, 2022.
