A flat plane of dark matter beyond the Local Group may explain why nearby galaxies move away from us instead of falling ...

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at ...

Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from ...

Hubble catches a spiral galaxy mid-flight, shedding glowing gas as it battles the harsh environment of a nearby galaxy ...

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

This idea is called the big bang model—which is an unfortunate name because it brings to mind a cosmos expanding like an ...

The suburbia of the Milky Way does not form a ball of matter with the center at its center. Rather, the mass around it is arranged in a wide, flattened form, which alters the sense of gravity back ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

Astronomers used James Webb Space Telescope data to determine the density of the universe's most mysterious "stuff." ...

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

A sheet of dark matter lying beyond the boundary of the Local Group is responsible for this.

For the first time, researchers have found what seems to be a cloud of dark matter about 60 million times the mass of the sun in our galactic neighbourhood ...
