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.

When the James Webb Space Telescope (JWST) began sending home its first deep-space images, astrophysicists knew that its suite of instruments would glimpse never-before-seen cosmological objects.

Known as the Hubble tension, the issue arises from conflicting measurements of how fast the universe is expanding. Now, a new ...

Thus, light from bodies located around 12 billion light-years away, like these supernovas, has experienced extreme wavelength lengthening, or " cosmological redshift." ...

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.
