How far can the most powerful telescope see into space?
SMRTR summary
The James Webb Space Telescope (JWST), launched in December 2021, is humanity's most powerful telescope, capable of observing 98% of the way back to the Big Bang. Its 21.3-foot primary mirror and infrared detection capabilities allow it to see objects too faint for visible light detection from vast distances. Orbiting at a stable Lagrange point nearly 1 million miles from Earth, JWST can detect galaxies like JADES-GS-z14-0 and MoM-z14, which existed just 280-290 million years after the Big Bang—surpassing Hubble's 13.4 billion-year reach.
