The object in question is a cosmic filament, a thread-like chain of gas that is about 5.5 million light-years in length and ...

The filament is a part of the vast cosmic web composed primarily of dark matter and interspersed with lighter layers of ...

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 SPT2349-56, ...

"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 behind ...

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 interplay of ...

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 formation.

This illustration provided by the European Southern Observatory in February 2024, depicts the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive ...

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 ...

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...
