Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

Scientists led by a team from the University of Chicago recently released a study that mapped some of the largest known objects in the universe. The study may help scientists test theories about how ...

A new high-resolution map of distant galaxies may help scientists understand a mysterious invisible substance that helps hold the universe together. The ordinary matter all around us — stars, planets ...

The Dark Energy Survey collaboration is releasing results that, for the first time, combine all of the data from an intensive six-year mapping of galaxies in the universe. The new analysis, of ...

A massive, spacetime-warping cluster of galaxies is the setting of today’s NASA/ESA Hubble Space Telescope image. The galaxy cluster in question is Abell 209, located 2.8 billion light-years away in ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

A galaxy made almost entirely of dark matter was sitting 300 million light-years away, unnoticed until astronomers applied a detection technique never before used for galaxy discovery. The find could ...

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The ...

The faint glow of individual stars stretching between two bright galaxies indicates that the galaxies are actively merging while the galaxy clusters that surround them merge as well. The image was ...

A galaxy so faint it escaped detection for as long as anyone has been scanning the sky has finally been found. Called CDG-2, this newly identified “ghostly” galaxy may be one of the most dark ...
