The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

These gigantic structures, which contain hundreds or even thousands of galaxies bound together by gravity, offer important ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

Mikhail Ivanov, Oliver Philcox, and Marko Simonović won the New Horizons Award for their work on large scale structures — the strands and filaments of our universe which contain buried clues to its ...

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date. When you purchase through links on our ...

After 10 years of searching, scientists have finally found the universe's 'missing matter'. For our cosmological models to work, scientists know there should be a certain amount of matter - the ...

The universe's expansion is accelerating, a phenomenon attributed to dark energy, potentially explained by a cosmological constant (Λ) in Einstein's general relativity. The ΛCDM model, the standard ...

Thinking about the edge of the universe is one of those ideas that fascinates pretty much everyone. We can map […] ...

Dr. Frank is an astrophysicist at the University of Rochester. Dr. Gleiser is a theoretical physicist at Dartmouth College. Not long after the James Webb Space Telescope began beaming back from outer ...

How did the universe start? Did we begin with a big bang, or was there a bounce? Might the cosmos evolve in a cycle of expansion and collapse, over and over for all eternity? Now, in two papers, ...
