US President Joe Biden on Monday unveiled the first image taken by the James Webb Space Telescope, which shows a cluster of galaxies with unprecedented accuracy, while the device is expected to provide unprecedented information about the cosmos.
The photo shows the named galaxy cluster SMAC 0723, more than 4 billion years. According to NASA CEO Bill Nelson, at least one of the bright streaks appearing in the “background” of the photo is more than 13 billion years old, or just 800 million years after the Big Bang.
“It’s a new window the history of our universe“Joe Biden said before unveiling the image.
The French National Center for Space Studies (CNES) pointed out on Twitter that the image released on Monday is “the most accurate and the furthest ever obtained. It represents a portion of the sky equivalent to the size of a grain of sand held at arm’s length.
Look for evidence of life in the universe
This photo released by the White House serves as a glimpse into the series of photos and spectrographic data that the American space agency, NASA, plans to release. unveil on Tuesday from a space center located in the state of Maryland.
Webb, designed by NASA to help shed light on the birth of the first galaxies, reached its final destination in solar orbit last January, around 1.5 million kilometers from Earth.
Consisting of a set of 18 hexagonal segments in gold-coated beryllium metal and 6.5 meters in diameter, the telescope can collect more light and observe more distant objects than its predecessor Hubble and other telescopes.
It should allowto obtain never-before-seen information about the cosmosdating back to just 100 million years after the Big Bang, the theoretical explosion that triggered the expansion of the observable universe about 13.8 billion years ago.
Its tools make Webb also ideal for look for evidence of potentially life-sustaining atmospheres around dozens of recently documented exoplanets – celestial bodies orbiting distant stars – and to observe worlds much closer to us, such as Mars and Titan, Saturn’s icy moon.
Webb is the result of a NASA-led international collaboration with European and Canadian space agencies.
