Astronomers using China's FAST radio telescope have discovered a compact hydrogen cloud devoid of visible stars. Containing nearly 500,000 solar masses of neutral hydrogen, it represents one of the strongest candidates yet for an isolated dark galaxy.
An international team led by the University of Duisburg-Essen has developed a high-resolution 3D model demonstrating how uneven stellar nurseries cast shadows that alter local chemistry and impact infrared signals detected by Webb.
Chile, home to some of the world's premier astronomical observatories, has brought its light-pollution regulations into full effect, protecting night skies from Atacama to Tierra del Fuego.
Using the James Webb Space Telescope, astronomers have detected gemstone-like features in the atmosphere of a blisteringly hot, marshmallow-density exoplanet, shedding new light on planetary structures.
Researchers have quantified diffusion and scattering within Solar Orbiter's Extreme Ultraviolet High-Resolution Imager, improving the precision and clarity of solar observations.
Astronomers have detected a massive black hole tearing apart a star more than 1,000 parsecs from its galaxy's center. The tidal disruption event, TDE 2023mfm, was tracked across multiple observatories.
The Hubble Space Telescope has captured a striking edge-on view of the intermediate spiral galaxy NGC 1827, located approximately 37 million light-years away in the constellation Columba.
An international research team participating in the ALMA COMPASS Large program has detected a rare form of methanol in deep space for the first time, advancing interstellar chemistry.
Astronomers utilized NASA's Chandra X-ray Observatory to determine the physical causes behind the 'Treble Clef' radio wave structure. The study unveils the dynamics of massive colliding galaxy clusters.
Astronomers at Caltech and NASA JPL are utilizing SPHEREx data to decode the atmospheric mysteries of brown dwarfs. The study reveals critical gaps in current stellar and planetary evolution models.
The James Webb Space Telescope has detected an unexpected signal twice, 88 days apart, emanating from a patch of space previously thought to be empty. Scientists are evaluating four possible origins.
The VERTECS astronomical nanosatellite, built by a Japanese university consortium, has concluded in-orbit testing. Meeting all performance standards, it has begun routine scientific observations.
More than 90 NSF NOIRLab volunteers welcomed visitors from the Tohono O’odham Nation to NSF Kitt Peak National Observatory to enjoy an evening of cultural performances and educational activities.
The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was found without the help of gravitational lensing. JWST observations suggest…
The speed of an asteroid's spin can tell astronomers a surprising amount about what it is made of. However, existing approaches to measuring spin based on telescope observations can often produce misleading estimates.
Diligent sleuthing by astronomers has broken open a cold case in the data archive of NASA’s Hubble Space Telescope. In a study published Monday in Nature Astronomy, researchers report uncovering a surprising chemical clue that indicates the white dwarf star HS 0209+0832 may host a second-generation…
Astronomers have used radio observations from the Atacama Large Millimeter/submillimeter Array (ALMA) to catch a dying star in the middle of a dramatic transformation, and the data show a ring that records its final outburst. The new research was posted to the arXiv preprint server on Sept. 18. The…
NASA, Hubble uzay teleskobunun yakaladığı ilginç bir kareyi paylaştı. Kameraya gülümseyen bir galaksi kümesi... ABD Havacılık ve Uzay Ajansı'nın (NASA) Hubble uzay teleskobu, evrenin gizemlerini gözlemlemeyi sürdürüyor. NASA 1990 yılından bu yana yörüngede çalışan Hubbe'ın kaydettiği çarpıcı bir…
James Webb Uzay Teleskobu, 2024 yılında MeerKAT dizisi tarafından tespit edilen ve şimdiye kadar gözlemlenen en uzak hız...
NASA has taken the next step in the process of developing a new all-glass telescope for the LISA (Laser Interferometer Space Antenna) mission, a space observatory designed to detect ripples in space-time called gravitational waves.
A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone expected. Using the James Webb Space Telescope, Brittany Miles, assistant astronomer at the University of Arizona's Steward Observatory, led a team that spent 11 hours staring…
First discovered in 2007, fast radio bursts are enigmatic, millisecond-long flashes of radio emission from the distant Universe. Their origin remains uncertain, particularly since most are seen once and never again. Astronomers using the NASA/ESA/CSA James Webb Space Telescope have pinpointed the…
The dimly glowing balls of gas formed like stars but in other ways resemble giant planets.

Astrobites reports on NASA’s SPHEREx mission, which is collecting an infrared spectrum for every point in the sky — potentially revolutionizing our understanding of cosmic inflation, galaxy formation, and interstellar ices.
For more than a quarter century, unidentified chemical signatures from a white dwarf star have laid dormant in the archive of the NASA/ESA Hubble Space Telescope, until diligent sleuthing by a young astronomer revealed something extraordinary: high amounts of the element niobium, and other unusual…
NASA'nın yeni gözlemevi Roman Uzay Teleskobu, yörünge öncesi testlerini tamamlayarak ilk ışığını yakaladı. Teleskobun yö...
In the early history of our Solar System, a Mars-sized object called Theia smashed into the infant Earth, vapourising massive amounts of rock and blasting it into space. Some of that material coalesced into the Moon. Astronomers have now used the NASA/ESA/CSA James Webb Space Telescope to examine a…
By studying radiant energy that only emerges in the far-infrared, PRIMA will address a wide range of questions about the universe.
This starry view of the nearby star-forming region IC 348 is one of the largest images from the NASA/ESA/CSA James Webb Space Telescope released to the public so far. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered…
