The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little ...
Before Webb, images like these only came from the Hubble Space Telescope, which rocketed into Earth's orbit in 1990. But the JWST pictures reveal the rewards of the 25 years and $10 billion NASA ...
Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, [2] within the southern constellation of Volans (RA/Dec = 110.8375, −73.4391667).
In this handout photo provided by NASA, NASA's James Webb Space Telescope reveals Stephans Quintet, a visual grouping of five galaxies, in a new light on July 12, 2022 in space.
SMACS J0723.3-7327 – a galaxy cluster at redshift 0.39, with distant background galaxies whose images are distorted and magnified due to gravitational lensing by the cluster. This image has been called Webb's First Deep Field. It was later discovered that in this picture the JWST had also revealed three ancient galaxies that existed shortly ...
The James Webb Space Telescope has produced its second revelatory image in as many days. Scientists using the observatory have discovered a tightly-packed "knot" of at least three galaxies that ...
[8] [9] Spectroscopic observations of GLASS-z12 by the Atacama Large Millimeter Array (ALMA) in August 2022 confirmed that the galaxy has a spectroscopic redshift of 12.117 ± 0.012, making it one of the earliest and most distant galaxies ever discovered, dating back to just 350 million years after the Big Bang, 13.6 billion years ago.
