A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...

Astronomers using the James Webb Space Telescope have discovered a rare jellyfish galaxy 8.5 billion light-years from Earth, offering a pristine look at how cosmic environments violently shut down ...

The discovery made by a large research team challenges the existing models of the universe.

A striking new image of our Milky Way's center, captured by the European Southern Observatory's ALMA, spans more than 650 ...

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

Learn how supermassive black holes may be suppressing star formation in nearby galaxies.

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.

"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 ...

Metallicity distribution of the first supernovae at 10 million years after the explosion. The supernova ejecta (orange region) has expanded to a radius of 1 kpc and enriched the surrounding gas to ...

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 ...

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, ...
