NASA Administrator Bill Nelson announced on June 29 that the agency will officially release the first images of the James Webb Telescope at 10:30 a.m. Eastern Time on July 12, which are "the first images of our universe in the history of our universe." The deepest image". Nelson said, "This is farther than humans have ever seen before, and we are just beginning to understand what Weber can and will do."

According to reports, the telescope, worth 10 billion US dollars and taking 20 years to build, will look back at the period after the "Big Bang" to uncover some mysteries about how the universe evolved. "We're getting history-making data," Nelson said.
NASA Jonathan Gardner, Webb associate senior project scientist at Goddard, said one of the goals of the Webb telescope is to find the first galaxies that formed in the universe after the Big Bang, so the images to be released will include the first ever Spectrum of the exoplanet .
These spectra measure the amount of light emitted at specific wavelengths and can provide insights into the composition of planets and their formation over the history of the universe.

In the six months since the James Webb Telescope launched on December 25, 2021, researchers and scientists have been ensuring that its massive mirrors were deployed correctly and that all of the scientific instruments were aligned and working.
It is larger than Hubble so it can see in dimmer light.

Gardner said those original small, faint galaxies merged together again and again over time to become the larger galaxies we now know, including our own Milky Way . "We will also see an example of how galaxies interact and grow," said Klaus Pontoppidan, Webb project scientist at the Space Telescope Science Institute.
