NASA, European Science Agency and Canadian Space Agency have come up to build James Webb Space Telescope that would be placed in the space to observe secrets of the Universe. JWST has sent data back to Earth and NASA revealed the sharpest, deepest infrared image of the early universe ever taken.
This is just the image of grain of sand held at arm’s length and the clarity difference between Hubble Deep Field to JWST infrared imagery is mind boggling. The data that it can transmit with the clarity and represent is unprecedented.
NASA while revealing the first picture wrote, “Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse
This isn’t the farthest back we’ve observed. Non-infrared missions like COBE & WMAP saw the universe closer to the Big Bang (~380,000 years after), when there was only microwave background radiation, but no stars or galaxies. Webb sees a few 100 million years after the Big Bang.
If you held a grain of sand up to the sky at arm’s length, that tiny speck is the size of Webb’s view in this image. Imagine — galaxies galore within a grain, including light from galaxies that traveled billions of years to us!
The James Webb Space Telescope is a collaboration between NASA, ESA & CSA_ASC. The Space Telescope Science Institute is the science & mission operations center for Webb. Tune in tomorrow at 10:30 am ET (14:30 UTC) as we continue to #UnfoldTheUniverse!”
