The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

The Universe may not have started with the Big Bang, but instead “bounced” out of a massive black hole formed within a larger “parent” universe, according to a new scientific paper. Professor Enrique ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of ...

Astronomers have identified what could be the largest structure ever observed in the known universe—a vast network of galaxy clusters and superclusters containing an astonishing 200 quadrillion solar ...

A surprising new study reveals that the first stars appeared in a pre-heated universe, challenging earlier ideas about early cosmic conditions.

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe.

A new AI-powered method is changing how scientists measure the universe. Developed by researchers at the Flatiron Institute and their partners, this technique offers a far more accurate way to ...

Astronomers have uncovered a vast cloud of energetic particles surrounding one of the most distant galaxy clusters ever observed, marking a major step forward in understanding the hidden forces that ...

If you thought the cosmic web was tangled enough, think again. A team of astrophysicists recently used gamma-ray bursts—those spectacular, enigmatic explosions of energy from the farthest reaches of ...

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the largest known structure in the universe in terms of length, scientists claim.
