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.
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.
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.
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.
