Astronomers have successfully charted a colossal cluster of galaxies, extending billions of light years. This unprecedented exploration into cosmic structures could provide new insights into the ...

A massive star on the distant outskirts of our Milky Way galaxy is seen blowing a powerful cosmic blowtorch in a new image ...

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, ...

For several years, the astronomers have been intrigued by the compact and luminous galaxies observed in great number in the remote Universe. They are dwarf by their sizes, and however radiate ten to ...

For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter ...

"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 ...

An impossibly bright galaxy is forcing scientists to rewrite the rules of the Big Bang’s aftermath. Here’s what you’ll learn ...

What was the universe like in the first few hundreds of millions of years after it came into existence? How did the first ...

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.

Sometimes, Hubble or other telescopes will capture two or more galaxies that are in the process of merging — called interacting galaxies. These huge collisions can warp one or both of the galaxies, ...

"We know these monster black holes exist at the center of galaxies near our Milky Way, but the big surprise now is that they were present at the beginning of the universe." When you purchase through ...
