Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution of matter. Now astronomers from China have made a large-volume search for hypervelocity stars by utilizing a special class of stars known for their distinct, […]
Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a “sterile” type of neutrino hypothesized to be responsible for previous experiments’ anomalous results, as detailed in a paper published in Nature.

Mid-infrared observations from NASA’s James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA’s Chandra X-ray Observatory, highlighted in blue. Together, these different wavelengths reveal a detailed and layered view of a pair of colliding spiral galaxies, captured in an image released on Dec. 1, 2025.

Even most rocket scientists would rather avoid hard math when they don’t have to do it. So when it comes to figuring out orbits in complex three-body systems, like those in cis-lunar space, which is between Earth and the moon, they’d rather someone else do the work for them.

Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the observational campaign, published December 19 on the pre-print server arXiv, shed more light on the nature of this source.
