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 ...
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).
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 ...
The two galaxies in the images are situated 326 million light-years from Earth in the constellation Hydra. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
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 captured new detailed portraits of 19 spiral galaxies filled with millions of stars and glowing gas and dust. ‘Mind-blowing’ new images reveal 19 galaxies ...
In 2024, two older and more distant galaxies, JADES-GS-z14-0 and JADES-GS-z14-1, were found. [ 6 ] JADES-GS-z13-0 is located in the Great Observatories Origins Deep Survey – South (GOODS-S) field in the constellation Fornax , which includes the Hubble Ultra Deep Field .
