Astronomers using the James Webb Space Telescope and gravitational lensing have identified LAP1-B as the most metal-poor early-universe galaxy yet observed, offering a rare look at conditions about 800 million years from

Using the James Webb Space Telescope and gravitational lensing, astronomers characterized the ultra-faint galaxy LAP1-B and identified it as the most metal-poor galaxy yet observed in the early universe.

New James Webb Space Telescope analysis suggests the extreme infrared output of W2246−0526, the most distant known Hot DOG, may be explained in part by polar dust rather than the torus alone.

A James Webb Space Telescope study of four nearby galaxies found that more massive star clusters break out of their birth clouds faster, adding new detail to how star formation shapes galaxies.

Astronomers using James Webb data have reconstructed the cosmic web at a new level of detail, offering a clearer picture of how galaxies formed and evolved across deep time.

A new combined view of the Whirlpool Galaxy is helping astronomers study how newly formed stars clear away surrounding gas and dust, a key process in galaxy evolution.

New James Webb Space Telescope observations of the planetary nebula Tc 1 are giving astronomers a sharper view of where buckminsterfullerene, or C60, emerges in space and how complex carbon chemistry develops around dead

Astronomers studying trans-Neptunian object 2002 XV93 report signs of a thin atmosphere, raising new questions about how such a small body could retain gas so far from the Sun.

A newly identified ‘X-ray dot’ spotted by Chandra may offer astronomers a crucial link between mysterious little red dots seen by JWST and the growth of supermassive black holes in the early universe.

Using 60 hours of continuous James Webb Space Telescope observations, astronomers have mapped the temperatures of TRAPPIST-1b and TRAPPIST-1c and found evidence that both Earth-sized worlds are rocky, tidally locked, and

New observations of 29 Cygni b with the James Webb Space Telescope are giving astronomers fresh evidence about how extremely massive gas giants may form and where the boundary between planets and stars begins.

NASA says James Webb Space Telescope observations of 29 Cygni b found evidence for heavy elements including carbon and oxygen, supporting the idea that the 15-Jupiter-mass object formed like a planet.

New James Webb observations of the Milky Way’s W51 region are exposing young stars and intricate structures previously obscured by dust, while comparisons with ALMA also show how much of star formation still remains ve,

New James Webb Space Telescope observations of W51 are exposing previously hidden young stars and the gas-and-dust structures around them in unusually fine detail.

New complementary observations from the James Webb and Hubble space telescopes are offering one of the most complete views yet of Saturn’s layered and dynamic atmosphere.

The James Webb Space Telescope has detected frozen carbon dioxide inside a planetary nebula for the first time — a cosmic first that expands our understanding of the chemical environments around dying stars.

A massive international collaboration using the James Webb Space Telescope and ALMA has identified 70 dusty galaxies from the universe's first billion years. These ancient objects appear to have formed stars far earlier than current models predict, potentially forcing a fundamental reassessment of how galaxies evolve.
