Reaching nanometer precision in space isn’t just hard—it’s nearly impossible. But JWST’s flexure-driven actuators do it while surviving cryogenic temps, vacuum, and launch forces.

Findings could imply that the Big Bang would no longer be an isolated event and suggest that every black hole in our universe ...

The James Webb Space Telescope has taken another look at the potential "city-killer" asteroid 2024 YR4 and found its chances ...

Inflation and budget issues are threatening to hobble NASA’s most in-demand telescopes.

The James Webb Space Telescope (JWST) has discovered that a hazy sky over frozen Pluto is helping to cool the dwarf planet's ...

A NASA-backed project using observations from the James Webb Space Telescope (JWST) has released more than 1.5 TB of data for ...
