Dark Universe

The vast, seemingly empty spaces between galaxies are not entirely empty. So what's in these cosmic voids?

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe.

Using data from the Euclid Space Telescope, astronomers have discovered a stunning 2,674 dwarf galaxies, the study of which could help better understand cosmic evolution.

Computer algorithms can model the universe, matching simulations to observations and revealing the distribution of dark matter.

Interactions between dark matter and dark photons during a "missing chapter" cosmic history could shed light on one of the most troubling cosmic mysteries.

The strength of dark energy in our universe is not optimized for forming stars, which means other universes might have a greater likelihood of producing life.

The secrets of dark matter might be hiding in the immense cosmic crashes that are colliding galaxy clusters.

Located at the confluence of several dark matter filaments in the cosmic web, the Coma Cluster of galaxies is the perfect case study for understanding how these galactic conurbations grow.

The concept of dark energy came about just around the time Space.com booted up.

A simulated universe created by a supercomputer should help astronomers better analyze dark matter and dark energy clues delivered by "dark universe detective" telescopes Roman and Rubin.
