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.
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.
