Each cube shows a specific cosmological redshift, from 9 to 1, with earlier cubes cast in redder shades. That last sentence describes where we’re at now.

NASA noted that Webb can identify extremely distant supernovae due to the cosmological redshift, which stretches their light into longer wavelengths. Learn more about the star-exploding story here.

NASA Telescope Discovers Exploding Stars 'Almost Everywhere' Published Jun 13, 2024 at 1:46 PM EDT Updated Jun 13, 2024 at 6:55 PM EDT By Jess Thomson ...

According to NASA, Webb's ability to detect extremely distant supernovae stems from their light being stretched into longer wavelengths, a phenomenon called cosmological redshift.

New images from NASA’s James Webb Space Telescope show the most distant star ever detected. It’s more than twice as hot as the sun.

Quantized redshift of cosmological objects would either indicate that they are physically arranged in a quantized pattern, or that there is an unknown mechanism for redshift that is not related to ...
