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 paper has been accepted for publication in The Astrophysical Journal.
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.
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 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 (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…
