Hace 5 días · Redshift. Absorption lines in the visible spectrum of a supercluster of distant galaxies (right), as compared to absorption lines in the visible spectrum of the Sun (left). Arrows indicate redshift. Wavelength increases up towards the red and beyond (frequency decreases).
13 de jun. de 2024 · A redshift of one corresponds to a distance of more than 10 billion light-years. JWST’s studies showed that JADES-GS-z14-0 has a redshift of 14.32, the highest ever recorded. (JADES-GS-z13-0 has...
6 de jun. de 2024 · GS-z14-0 was discovered to have a redshift of 14.3, besting the 2022 record of a galaxy found with a redshift of 13.2 that corresponded to a formation age of some 325 million years after the...
30 de may. de 2024 · The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy.

17 de jun. de 2024 · The galaxies that emitted that light are called high-redshift galaxies, where redshift is indicated by the letter z. Since its shifted into the red, only infrared telescopes can see it....
Hace 6 días · For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.
