A groundbreaking Canadian-led mission proposal could revolutionize the way scientists search for habitable planets beyond our solar system, zeroing in on some of the smallest and dimmest stars in the galaxy. As outlined in a recent study published on...

data upends our view of a nearby lava planet, revealing puzzling activity deep beneath its surface. Using the James Webb Space Telescope, astronomers have captured five eclipses of the rocky world 55 Cancri e, located roughly 41 light‑years from Earth....

3378b does not transit its star from our viewpoint, astronomers cannot employ transit spectroscopy—the method the James Webb Space Telescope uses to probe atmospheres of transiting worlds like those in the TRAPPIST‑1 system. Consequently, any atmosphere...

the scientists synthesized data from ALMA, the U.S. National Science Foundation’s Very Large Array (VLA), the James Webb Space Telescope (JWST), and the Very Large Telescope (VLT). By integrating radio and infrared observations, the team could correlate...

temperatures triggering the formation of its coma and tail. Credit: NASA/JPL-Caltech Follow-up data from the James Webb Space Telescope (JWST), as detailed in a report on the arXiv preprint archive, identified carbon dioxide as the primary driver of...

about 10 millibars, is orders of magnitude thicker. The puzzle deepens because earlier observations with the James Webb Space Telescope found no surface ices of nitrogen, methane or carbon monoxide on 2002 XV93—volatile compounds that normally fuel...

moons that may explain why its satellite system is unlike any other in the solar system. New evidence from the James Webb Space Telescope (JWST) indicates that the rings and minor moons of Neptune may be composed of debris from a shattered, ancient...

an ancient satellite system shattered by a violent cosmic event billions of years ago. New observations from the James Webb Space Telescope indicate that the tiny inner moons of Neptune may be the shattered remnants of a once‑larger satellite family...

team can now provide concrete predictions of how the early Milky Way would have appeared to instruments like the James Webb Space Telescope (JWST) and the Hubble Space Telescope. Testing Physics Through Cosmic Evolution Because humans cannot observe the...

gas, proving that the ingredients for life existed remarkably early in the cosmos. New observations from the James Webb Space Telescope (JWST) have revealed that the infant universe was far more chemically active than previously assumed. Researchers...

of exoplanet WASP-17b, revealing new structural details 1,300 light-years from Earth. Astronomers utilizing the James Webb Space Telescope (JWST) have unveiled a striking atmospheric asymmetry on the hot Jupiter exoplanet WASP-17b, located roughly 1,300...

young giants swaddled in dense, light-scattering cocoons that have misled astronomers for years. When the James Webb Space Telescope (JWST) first began peeling back the layers of the early universe, astronomers expected to see the faint, orderly...

of mysterious supermassive black holes in the early universe. Among the most perplexing targets identified by the James Webb Space Telescope (JWST) are the so-called “Little Red Dots”—compact, crimson-hued objects scattered across the early universe....

red dots suggest massive black holes may have formed and grown before their host galaxies even took shape. The James Webb Space Telescope (JWST) has shed new light on one of the most puzzling phenomena in the early universe: the “little red dots.” These...

al, Nature Astronomy To bypass these limitations, a research team leveraged the unprecedented capabilities of the James Webb Space Telescope. By employing a stacking technique on data from 217 individual “little red dots,” researchers were able to...

detailed in The Astrophysical Journal Letters, were made possible through the advanced sensitivity of the James Webb Space Telescope. Of the more than 6,300 exoplanets currently cataloged by scientists, only a fraction are rocky worlds that appear to...

power and the measurement challenges within its growing public archive. Analysis of public data from the James Webb Space Telescope has revealed a highly stretched galaxy whose light has been bent by a massive foreground cluster, underscoring how hidden...

in essence, an ultimate “cheat sheet” for where to point the world’s most powerful telescopes. Prioritizing the James Webb Space Telescope Observing time on instruments like the James Webb Space Telescope (JWST) is fiercely competitive and extremely...

suggesting galaxy interactions may drive the rapid growth of supermassive black holes. New analysis from the James Webb Space Telescope (JWST) has identified four candidate pairs of “little red dots” (LRDs) in the early universe, suggesting that some of...

660 Myr after the Big Bang, shedding light on JWST’s red dots and rapid black‑hole growth. Observations with the James Webb Space Telescope have turned a faint point of light known as MoM‑BH*‑1 into a compelling case for a black hole enshrouded by...
