The main topic of Ashraf Uddin's discussion was determining the Hubble Constant, which is the rate of expansion of the universe, through the observation of Type 1a supernovae. For the convenience of ...

Because type 1a supernovae produce consistent peak brightness, measuring their brightness when observed from Earth can reveal how far away they are. "Type Ia supernovae are extremely valuable in ...

This trio won the 2011 Nobel Prize in Physics for this work. While dim supernovae might not seem like a major find, these astronomers were looking at Type 1a supernovae, which are known to have a ...

They use JWST to explore its earlier results of the cepheid/supernova distance ladder. This has been used to establish distances across the cosmos using Cepheid variable stars and Type 1a supernovae.

“That reminds of of being a star in space and having other stars gather with me until we create a supernova and result in a new universe ... “Time series images (15 Sep 2023 & 29 Dec 2024) of EOS-04 ...

The James Webb Space Telescope (JWST) has caught yet another visual spectacle, depicting layers of interstellar material illuminated by a supernova in a phenomenon known as a thermal light echo.
