Galaxies, including the Milky Way, grow from thick, turbulent disks into layered structures. JWST’s images show this process ...

Unusually fast-moving gas clouds near a nearby galaxy suggest they may have come from outside the galaxy. Scientists have ...

A quiet, glowing gas cloud has been hiding in plain sight not far from Earth. For decades, astronomers have predicted that ...

An interstellar object called 3I/ATLAS is now moving through our solar system, the third one we've seen in the last eight ...

The Vera C. Rubin Observatory's first image release includes a 'staggering' view of 10 million galaxies in and around the ...

Our Milky Way and Andromeda are the two largest galaxies in the Local Group, a cluster that includes around a hundred smaller galaxies. Astronomers have known for over a century that Andromeda is ...

Exactly which of these scenarios ultimately occurs could be governed by the masses of the Large Magellanic Cloud (LMC) and the Triangulum galaxy, two galactic players in the Local Group.

Both the Milky Way and the Andromeda galaxies (M31) are part of what's known as the Local Group (LG), which also hosts other smaller galaxies (some not yet discovered) as well as dark matter (per ...

A collision between our Milky Way galaxy and its largest neighbor, the Andromeda galaxy, predicted to occur in about 4.5 billion years, has been anticipated by astronomers since 1912.

After factoring in the gravitational pull of Local Group galaxies and running 100,000 simulations using new data from the Hubble and Gaia space telescopes, the team found there is about a 50% ...

Approaching, but not directly The Andromeda and Milky Way galaxies are the two biggest galaxies in our section of the universe, referred to as the Local Group. Despite being 2.5 million light ...
