The James Webb Space Telescope has revealed a lopsided exoplanet and blistering winds on its evening side, challenging the familiar image of an evenly illuminated world. The finding shows how observations can expose differences across an exoplanet’s atmosphere.

The James Webb Space Telescope has revealed a lopsided exoplanet and blistering winds on its evening side, challenging the familiar image of an evenly illuminated world. The finding shows how observations can expose differences across an exoplanet’s atmosphere.
Researchers using the James Webb Space Telescope tracked water-cloud changes in a brown dwarf about 7.5 light-years away, while separate studies describe deformed atmospheres on ultra-hot exoplanets and gemstone-forming conditions on a scorching, low-density world. Together, the findings extend observations of weather and atmospheric structure beyond the planets in our solar system.
Teams behind the James Webb and Hubble space telescopes have released new images capturing stellar nurseries, galaxies and gravitational lensing. Webb is jointly operated by NASA and the European Space Agency, with the Canadian Space Agency also participating; both observatories contributed to the latest collection.
The newly observed “little red dots” have prompted questions about what they can reveal about the early universe. Scientists do not yet know what the objects are or what they may show, making their identification a key step in assessing their significance for understanding cosmic origins.

Astronomers used the James Webb Space Telescope to study a distant fast radio burst, seeking clues to how these brief, powerful radio signals originate. The observations add evidence from a far-off event to a still-unresolved astrophysical question; the available report provides no further details on the burst or findings.
Astronomers are using the James Webb Space Telescope to study young star systems and their extreme debris disks, seeking evidence about how planetary systems evolve. The observations may help test theories about the early solar system, including the hypothesis that a Mars-sized body called Theia collided with the infant Earth.

Astronomers using the James Webb Space Telescope have detected the most distant fast radio burst ever observed, more than doubling the previous distance record. The burst’s source surprised scientists, though the available report does not specify what they found unexpected.
High activity
James Webb Space Telescope observations indicate that galaxies were producing and dispersing heavy elements just 500 million years after the Big Bang. Separately, NASA selected PRIMA, a far-infrared mission concept using spare Webb hardware, for further development toward a potential 2033 launch.
