James Webb Space Telescope: NASA reveals 1st full-colour image to the world
Global News
The most powerful space telescope ever built, James Webb is set to deliver its first full-colour scientific images to the world this week.
It’s a day that’s been highly anticipated in astronomy circles and beyond. Monday we will get the deepest view of the cosmos ever captured, thanks to the extraordinary capabilities of the James Webb Space Telescope (JWST).
The first image from the $10-billion telescope is going to show the farthest humanity has ever seen in both time and distance, closer to the dawn of the universe and the edge of the cosmos.
U.S. President Joe Biden will reveal the first image around 5 p.m. ET, followed by four more galactic beauty shots on Tuesday.
NASA said Biden will show a “deep field” image. That shot is likely to be filled with lots of stars — “lots” being an understatement — with massive galaxies in the foreground distorting the light of the objects behind, telescoping them and making faint and extremely distant galaxies visible. Part of the image will consist of light from not too long after the Big Bang.
The images to be released Tuesday include a view of a giant gaseous planet outside our solar system, two images of a nebula where stars are born and die in spectacular beauty and an update of a classic image of five tightly clustered galaxies that dance around each other.
The JWST is the successor to the Hubble Space Telescope, which has not only provided stunning images, but has also been vital in providing scientific knowledge about our universe and its origins.
The JWST has a much larger primary mirror than Hubble (2.7 times larger in diameter, or about six times larger in area), giving it more light-gathering power and greatly improved sensitivity over the Hubble.
The JWST launched, and there were no second chances — its extremely distant location in the solar system makes it impossible for human crews to work on.
