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 reveal more detail than ever in the unusual and rare supernova remnant.
Astronomers from the University of Warwick examined 151 white dwarfs situated approximately 65 light-years from Earth. Detailed spectral analyses reveal unexpected optical and atmospheric properties in these stellar remnants.
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.
