Unveiling Webb space telescope’s first full-color image of distant galaxies
U.S. President Joe Biden on Monday released 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 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 $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 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.
“It’s a new window into the history of our universe,” Biden said before the picture was unveiled. “And today we’re going to get a glimpse of the first light to shine through that window: light from other worlds, orbiting stars far beyond our own. It’s astounding to me.”
