The photo from the largest and most powerful space science telescope ever launched was unveiled by U.S. President Biden on Monday afternoon
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. At least one of the faint, older specs of light appearing in the “background” of the photo – a composite of images of different wavelengths of light – dates back more than 13 billion years, Nelson said. That makes it just 800 million years younger than the Big Bang, the theoretical flashpoint that set the expansion of the known universe in motion some 13.8 billion years ago.Article content
“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.” He was joined at the Old Executive Office Building of the White House complex by Vice President Kamala Harris, who chairs the U.S. National Space Council.On Friday, the space agency posted a list of five celestial subjects chosen for its showcase debut of Webb. These include SMACS 0723, a bejeweled-like sliver of the distant cosmos that according to NASA offers “the most detailed view of the early universe to date.
