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 class of young stellar systems that show signs of similar upheavals, providing clues to the amount of energy in their…
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.
