Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient ...

Astronomers have discovered a previously hidden "cosmic fuel tank" in an infant cluster of forming galaxies. This vast reservoir of cool molecular gas is found in the protocluster known as ...

"To make progress towards a theory of galaxy formation, it is crucial to compare results and codes from different simulations. We have now done this by bringing together competing code groups ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex ...

The European Space Agency's Euclid mission—designed to map the geometry of the dark universe with unprecedented precision—continues to deliver its first scientific insights. The Euclid Consortium has ...

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star ...

Sci-fi tends to paint the edge of our galaxy as a desolate backwater, but in one early galaxy, the galactic rim is the bright, bustling center of activity, and the core is the aging backwater. The ...

The vantage point at Cerro Pachón, with its dark skies and high-altitude clarity, enhances the richness of the image.
