James Webb Space Telescope

As part of the 2023 Holidays at the White House, First Lady Jill Biden debuted the first-ever White House Advent Calendar and is celebrating with this new image from the JWST. In it, supernova remnant Cassiopeia A (Cas A) gleams against the…

To say that the James Webb Space Telescope (JWST) is upending our thoughts about the universe is an understatement. Scientists were shocked when they saw the telescope's first images of the universe's earliest galaxies. The galaxies…

Saturn has more moons than any other planet in our solar system. With the recent discovery of 62 new spatial bodies in the system, the ringed planet now has a total of 145 moons, beating Jupiter’s 92, which also increased in February with …

The James Webb Space Telescope (JWST) has been unlocking many mysteries, and now it's finding multiple galaxies that grew massive too soon after the Big Bang if the standard model of cosmology is to be believed. In a study published in …

A research team used the James Webb Space Telescope data to pinpoint the precise location of what they call the “engine” of the merging galaxy. They published their results in The Astrophysical Journal Letters. The team at the Hiroshima…

Rice University astronomers reviewed the first images from NASA’s James Webb Space Telescope and saw telltale signs from two dozen previously unseen young stars approximately 7,500 light years from Earth. The published research provides…

In galaxy clusters, tremendous tidal forces pull out a fraction of stars that wander off into intergalactic space. The faint light emitted by these stars is called intracluster light (ICL) and has a brightness of less than 1% of the…

The James Webb Space Telescope revealed the first detailed molecular and chemical portrait of a distant world's sky. The telescope’s array studied WASP-39 b, a planet nearly as massive as Saturn orbiting a star some 700 light-years away.…

The James Webb Space Telescope and the Hubble Space Telescope captured views of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world's first-ever in-space test for planetary defense.…

The Webb Space Telescope returned its first images of Mars. The data comes from the telescope’s infrared instruments and provides scientists with information about Mars’ surface and atmospheric composition. Using the Near-Infrared…
