These are the farthest galaxies we've ever been able to see. The first science image from the James Webb Space Telescope is a deep view of the universe, showing galaxies galore
Zoom in enough on any patch of space, and it’ll be teeming with distant galaxies. The first deep-field image from NASA’s is zoomed in further than any previous infrared picture of the cosmos, a record that won’t stand for long as the massive observatory continues to push the limits of astronomical observation. It has revealed galaxies we have never been able to see before.around the sun in early 2022.
The small specks and streaks of light amplified by the lens and visible around the edges of the image are distant, incredibly faint galaxies – some of the first that ever formed.The most powerful telescope ever made is finally ready to gather fresh clues relating to questions we could only dream of answering with its predecessors.
We couldn’t see these galaxies before now partially because of the expansion of the universe: the further away an object is, the faster it is moving away from us and the redder its light appears because of that motion. JWST’s predecessor, the Hubble Space Telescope, observes light mainly in visible wavelengths, but, allowing it to spot objects that appear so red that they’ve become invisible to Hubble.
“We think that when stars form from primordial material in the distant universe, they form in a very different way, but we’ve never really observed that before,” says at the University of Sussex in the UK. “There’s a lot of crucial physics there that we don’t know anything about.”
