Webb Telescope Provides New Cosmological Insights

The James Webb Space Telescope has provided groundbreaking insights, capturing Centaur 29P/Schwassmann-Wachmann 1 and revealing gas jets, including carbon dioxide and carbon monoxide, though water was not detected. Webb also captured a supernova appearing three times due to gravitational lensing, aiding in measuring the Hubble constant and highlighting the discrepancy known as Hubble tension, which arises from differing measurements of the universe's expansion rate. The supernova 'H0pe' was observed through a 'trifold mirror' lensing effect, enhancing understanding of cosmic expansion. Additionally, Webb has imaged the supernova remnant Cassiopeia A, located 11,000 light-years away, contributing to stellar evolution studies. These observations underscore the telescope's profound impact on our understanding of the universe.
