The speed of an asteroid's spin can tell astronomers a surprising amount about what it is made of. However, existing approaches to measuring spin based on telescope observations can often produce misleading estimates.
Astronomers have launched a citizen science initiative to uncover hidden black holes in the Milky Way. Volunteers will comb through vast NASA telescope archives to identify key gravitational signatures.
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.
The highly anticipated Orionid meteor shower is set to reach its peak activity overnight on October 21-22. Stargazers can look forward to a spectacular celestial display of shooting stars lighting up the autumn night sky.
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.
