Here’s how it works. Astronomers have discovered something surprising about the universe's smallest and faintest class of galaxies: Ultra-Diffuse Galaxies (UDGs). A research team studying these ...

The detection of polycyclic aromatic hydrocarbons—carbon-based molecules often associated with star-forming regions—suggests potential for stellar activity, though the Sombrero galaxy remains ...
