WASHINGTON, D.C.: U.S. President Joe Biden and NASA's chief Bill Nelson released on Monday (July 11) the debut photo from NASA's James Webb Space Telescope - an image of a galaxy cluster revealing the most detailed glimpse of the early universe ever seen.

The White House sneak peek of Webb's first high-resolution, full-color image came on the eve of a larger unveiling of photos and spectrographic data that NASA plans to showcase on Tuesday at the Goddard Space Flight Center in suburban Maryland.

The image showcased by Biden and NASA chief Bill Nelson showed the 4.6 billion-year-old galaxy cluster named SMACS 0723, whose combined mass acts as a "gravitational lens," distorting space to greatly magnify the light coming from more distant galaxies behind it.

Nelson said that the thousands of galaxies were captured in a tiny patch of the sky roughly the size of a grain of sand held at arm's length by someone standing on Earth.

Webb was constructed under contract by aerospace giant Northrop Grumman Corp. It was launched to space for NASA and its European and Canadian counterparts on Christmas Day 2021 from French Guiana, on the northeastern coast of South America.

The $9 billion Webb observatory, the largest and most powerful space science telescope ever launched, was designed to peer through the cosmos to the dawn of the known universe, ushering in a revolutionary era of astronomical discovery.

The highly anticipated release of its first imagery follows six months of remotely unfurling Webb's various components, aligning its mirrors, and calibrating instruments.
