James Webb Space Telescope observations of Neptune’s inner moons and dusty rings detect clay minerals that require long-term water–rock interactions, implying these moons expose deep interiors from a past catastrophe. The study supports a scenario in which Triton was captured early, disturbing Neptune’s original moons and leaving the current inner moons to form from the resulting debris.
New JWST observations and simulations identify L98-59d as a 1.6 Earth-radius exoplanet with a global magma ocean, a molten core, surface temperatures near 1900°C, and a hydrogen-sulfide atmosphere shaped by strong tidal forces; this suggests molten planets may be more common than thought and that some planets in the habitable zone might not be habitable after all.
The James Webb Space Telescope captured a detailed image of the Sagittarius B2 molecular cloud, a highly efficient star-forming region about 26,000 light-years away, revealing complex chemical areas and offering clues to its extraordinary star production despite limited gas resources.
The James Webb Telescope has observed a distant exoplanet, PSR J2322-2650b, with an unusual atmosphere composed of soot and diamonds, challenging current understanding of planetary formation and composition, especially given its proximity to its pulsar host star and its unique chemical makeup.
The James Webb Space Telescope has released a stunning image revealing a dense cluster of galaxies and cosmic filaments in the early universe, providing new insights into galaxy formation, the structure of the cosmic web, and the influence of dark matter and dark energy, with observations reaching back over 13 billion years.
The James Webb Space Telescope captured a detailed image of the merging spiral galaxies NGC 2207 and IC 2163, revealing an intricate web of cosmic chaos, complemented by Chandra's X-ray data highlighting high-energy regions, providing insights into galaxy interactions.
A new image from the James Webb Space Telescope shows the intricate chaos of two colliding spiral galaxies, NGC 2207 and IC 2163, combining infrared and X-ray data to reveal the complex interactions and star formation processes during their gravitational merge.
Scientists have discovered a bizarre, lemon-shaped exoplanet called PSR J2322-2650b orbiting a pulsar, with a mysterious carbon-rich atmosphere that may produce diamonds, challenging current understanding of such systems. Additionally, breakthroughs include the creation of the shortest X-ray pulses, fossilized bee nests inside mammal bones, and evidence that swearing can improve physical performance.
The JWST observed the 'super-puff' exoplanet WASP-107b, which is losing its helium-rich atmosphere rapidly as it orbits close to its star, providing insights into atmospheric escape processes on distant worlds.
Astronomers using the James Webb Space Telescope have potentially identified some of the universe's first stars, known as Population III stars, in a distant galaxy cluster, providing insights into early galaxy formation and the conditions of the universe shortly after the Big Bang.
Astronomers have discovered a rogue planet, Cha 1107-7626, that is rapidly accreting gas and dust at a record rate, acting like a star, which could provide insights into planetary and stellar formation processes.
Recent observations by the James Webb Space Telescope suggest that some black holes in the early universe may have formed from primordial collapse before galaxies, challenging traditional models of galaxy and black hole co-evolution and indicating that black holes could have grown rapidly or even predated their host galaxies.
Recent observations by the James Webb telescope suggest that supermassive black holes may have formed before galaxies, possibly from primordial black holes or dark matter collapse, challenging previous theories about their origins and indicating that such phenomena are less exotic than once thought.
The James Webb Space Telescope captured a detailed image of the Red Spider Nebula, showcasing the complex gas and dust structures from a dying star, offering insights into the future of our own sun as it becomes a red giant billions of years from now.
Two Australian PhD students developed a software fix that restored the James Webb Space Telescope's imaging clarity, allowing it to capture unprecedented detailed images of celestial objects without physical repairs, showcasing innovative use of neural networks and simulations.
