The James Webb Space Telescope captured photos of one of the earliest supernovas ever ... This background image of the region around supernova remnant Cassiopeia A was released by NASA’s Spitzer ...
The supernova progenitor was a white dwarf star, the progenitor of all Type Ia supernovae. The gravitational lens is galaxy cluster PLCK G165.7+67.0 (at a redshift of z=0.35), which lensed the supernova and its host galaxy. [5] [6] The determination for the Hubble Constant (H 0) using this Type Ia supernova was 75.4 kilometers per second per ...
A team of scientists published their findings this week using Nasa's James Webb Space Telescope (JWST) to cross-check the physics problem known as "Hubble Tension," which refers to Hubble Space ...
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy.As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [9]
The James Webb Space Telescope (JWST) has significantly advanced our understanding of supernovae [41] by identifying around 80 new instances through its JWST Advanced Deep Extragalactic Survey (JADES) program. This includes the most distant spectroscopically confirmed supernova at a redshift of 3.6, indicating its explosion occurred when the ...
The update provided by the James Webb Space Telescope features a galaxy cluster called SMACS 0723. In Webb's First Deep Field, the cluster is composed primarily of the fuzzy blobs seen across the ...
The photometry was obtained on the 1 m Swope Telescope at the Las Campanas Observatory. Observations were acquired twice per night in order to look for small scale fluctuations in the light curve. [3] The brightness and close proximity of SN 2021aefx make it an excellent target for nebular-phase James Webb Space Telescope observations. Kwok et ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
