The deepest and most detailed image of the universe to ever be captured was unveiled by NASA and President Joe Biden.
The photo is named "Webb's First Deep Field" and shows the universe only a few hundred million years after the Big bang. It took roughly 13 billion years for this starlight to travel to us, arriving at the James Webb Space Telescope after the space-time warping pull of the galaxy cluster SMACS-0723 steered even the fainter and more distant light away from us.
Bill Nelson said at the press conference that NASA is going back 13 billion years. We're going back almost to the beginning now that we know the universe is more than 13 billion years old. Nelson said that the telescope's view of the universe would allow scientists to find answers to questions that haven't been asked yet.
Ahead of debut science images, the telescope reaches "perfect" alignment.

Nelson said that the image was just the smallest slice of the night sky.
"Mr President, if you held a grain of sand on the tip of your finger at arm's length that is the part of the universe that you're seeing, just one tiny speck of the universe." Nelson made a statement. We used to think there was only one galaxy. The number is unrestricted. Billions of stars or suns can be found in our universe. There are a lot of stars and suns.
The Hubble Space Telescope has held the record for capturing the deepest glimpse into space. A series of deep image fields showed how our universe was formed hundreds of millions of years after the Bigbang. To peer even further back in time, scientists needed to design a telescope large enough to capture light from the faintest objects and capable of detecting the mid-IR frequencies the most distant light had been shifted to.
The telescope can be entered by entering. Hubble's mirror is just 7.9 feet wide in diameter. The JWST is able to detect objects 100 times fainter than Hubble. The universe can be seen using the telescope, which can see the universe in a new way.
After being launched from French Guiana atop an Ariane, the JWST was isolated from heat signals on Earth and now rests at a stable location beyond the moon. NASA engineers adjusted the telescope's instruments and mirror segments in order to get the first images. The telescope was struck by a micrometeoroid sometime between May 23 and May 25 but the impact did not damage the spacecraft.
The image is the first one collected. At 10:30 a.m. on Tuesday, there will be a ceremony. A stellar nursery, the atmosphere of a distant exoplanet, and a figure eight-shaped gas explosion from a dying star are some of the images NASA is releasing. Live Science and NASA have websites where you can follow the release.
Biden said at the press conference that it showed what we can achieve and what more we can discover.
