Scientists discovered the Milky Way lies within a vast flat dark-matter sheet spanning about 32 million light-years.

A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-scale distribution of ...

Every year, AIP awards physical scientists for their leadership and excellence. In recognition of women in the physical ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...

Most of the (dark) matter beyond the Local Group of galaxies (which includes the Milky Way and the Andromeda Galaxy) must be ...

Apple TV's multiverse sci-fi thriller, Dark Matter, starring Joel Edgerton, is surging up the charts ahead of the new season.

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

Astronomers have spotted a galaxy so faint, it’s almost invisible — a discovery that could help illuminate one of the most ...

Astronomers just uncovered something strange about our galactic neighborhood. The Milky Way may not sit inside a simple halo of invisible matter after all.

A groundbreaking computational physics framework has demonstrated that the three-dimensional fabric of the universe can be generated from scratch using a simple algorithm with exactly zero free ...

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 ...
