Located in the constellation Scutum, the Wild Duck Cluster (M11) remains prominent in the evening sky for several hours after sunset. This young cluster offers amateur and professional astronomers an exceptional observing target.
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.
Astronomers utilized decades of archival data and radial velocity measurements to search for exoplanets around 70 Oph AB. Ruling out Jupiter-mass worlds leaves the door open for Earth-sized planets.
Astronomers have obtained a closer look at J0404+1112, a rare white dwarf and brown dwarf binary. The system allows researchers to investigate a substellar atmosphere exposed to extreme radiation.
A new study reveals that neutrino flavors could play a decisive role in the fate of massive stars, dictating whether they erupt into a supernova or collapse directly into a black hole.
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.
New research links a host star's mass directly to the architecture of its planetary system. This stellar influence organizes planetary systems into two distinct families.
Combining cold dark matter simulations with observations of stellar streams and globular clusters, researchers inferred a declining power-law initial mass function for globular 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.
University of Warwick astronomers have shown that white dwarf stars can glow in a range of colors, including the first star ever found that would appear green to the human eye.
The edge of the Sun appears darker than its central region. This effect is known as limb darkening and tells us about the solar atmosphere. This same limb darkening effect has now been observed on several nearby stars and could help us improve our understanding of stellar atmospheres.
Globular clusters have far fewer binary stars than the solar neighborhood. New research identifies black hole burning as the culprit.
When a supernova exploded in 1181, Chinese and Japanese sky-watchers recorded it. They couldn't have known what the object was, and why it appeared for six months then disappeared. But in our modern times, we know it was a supernova, and we've even, most likely, found its remnant. New observations…
A new study reveals that the Chandrasekhar limit setting the upper mass bound for white dwarfs is not absolute. Highly magnetized white dwarfs might overcome this threshold.
Astrophysicists think that hypernovae are the most powerful stellar explosions in the Universe. They're the most explosive type of core-collapse supernova. But the evidence for them is not voluminous, and new research pokes holes in it, pointing out that hypernovae may not actually exist.
Astronomers detected an unusual triangular light curve about 300 light years away. They were searching for Black Widow Binaries, where a dense neutron star eats its companion. But they found something different: an M dwarf slowly eating its binary companion brown dwarf.
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…
Analyzing a sample of 300 of the best-characterized planetary systems among the more than 1,000 known in the Milky Way, an international research team led by the Italian National Institute for Astrophysics (INAF) has discovered that the multiplanet systems identified so far belong to two distinct…
In the early moments of the big bang, two elements were forged: hydrogen and helium. Technically, the tiniest traces of light elements such as lithium were produced as well, but nothing of consequence. The early universe was about three parts hydrogen to one part helium. All the heavier elements…
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…
Astrobites reports on why interstellar magnetic fields can appear ordered or tangled, depending on which gas clouds you measure and how.
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…
Researchers have discovered a millisecond pulsar with two stellar companions — one of only a handful of these rapidly spinning stellar remnants known to be in a triple system.
The stellar gathering known as Garro 04 belongs to a growing number of enigmatic groupings that combine traits of young open clusters ancient globulars.
The dimly glowing balls of gas formed like stars but in other ways resemble giant planets.
Gokul P. Srinivasaragavan et al 2026 ApJL 1006 L36 Through modeling, researchers determined that a recently discovered supernova accompanied by an X-ray flash likely gave rise to a long-lived magnetar that may be surrounded by an accretion disk.
The molecular cloud complex G12.79+0.43 contains 82 young stellar object candidates; while this complex is spatially associated with a larger superbubble, it’s not yet clear if there is a causal association.
Eruptions taking place in different locations on the Sun (e.g., on the solar limb versus on the disk) appear to have different spectral characteristics, paving a way for source regions of stellar flares to be studied.
A new catalog of giant pulses from the Crab Nebula pulsar reveals a feature predicted to exist but not seen until now.
The Gemini North telescope located on Maunakea in Hawai‘i has revealed the most detailed view yet of Pa 30, the likely remnant of the historic supernova seen in the year 1181. The new observations reveal that its famous “firework” filaments are not smooth streaks, but chains of tiny knots.

The upcoming Wide Fast Deep and Deep Drilling Field surveys have limited potential to confirm exoplanets, with just a handful of hot planets around M-dwarf stars likely to be confirmed in the Deep Drilling Field.
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…
Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star. New research investigates a potential link between this event and a supernova.

Image: This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in great detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300…
Image: Though the spiral galaxy in this new image by the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. It’s one of over one thousand galaxies in the Virgo Cluster, the…
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.
