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 ...

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 ...

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

A group of astronomers led by Evuda Wempe, a graduate student from the Kaptein Institute in Groningen, discovered a giant structure surrounding a Local group of galaxies, including the Milky Way and ...

Earth and the entire Milky Way galaxy might be sitting inside an enormous, mysterious void—a giant cosmic hole making our universe expand faster right here than anywhere else. This unusual idea, ...

Cosmologists have discovered new evidence from the early universe that suggests we are living in a giant void. After studying sound waves from the initial moments of the universe – essentially the ...

Now that we have tools to find vast numbers of voids in the universe, we can finally ask…well, if we crack 'em open, what do we find inside? The answer is a whole bunch of nothing. You probably could ...

New research presented at the Royal Astronomical Society's National Astronomy Meeting (NAM) in Durham suggests a revolutionary possibility: Earth and the entire Milky Way galaxy might be nestled ...
