Even small asteroids can do a lot of damage—and new research shows the James Webb Space Telescope is adept at spotting the tiniest of space rocks. A time-lapse of images from NASA’s James Webb ...

Those payloads range from a camera to take images of the dust plume created by the lander during its descent to one designed to see if GPS and Galileo navigation signals can be used at the moon.

The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

JWST has proven to be ideal for the discovery, researchers say, thanks to the telescope's sharp infrared eyes that detect the asteroids' thermal emissions. These infrared emissions are much ...
