Arizona is an ideal spot to see the Milky Way thanks to its numerous dark-sky places. Here's the best time to see - and ...

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo. The most distant of these stars is more than a million light years from Earth, ...

A study published in Nature Astronomy suggests that there is a 50-50 chance of the Milky Way and the Andromeda galaxy colliding in the next 10 billion years. The study used observations from the ...

Astronomers have found a new way of accurately mapping the outer gas disk of the Milky Way using the positions of young stars ...

The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about ...

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, ... meaning if their distance is more than around 500,000 light-years, ...

But “the density of the Milky Way stars — they should have a dip around 300 kiloparsecs ... The 208 RR Lyrae stars detected by the team range in distance from 20 to 320 kiloparsecs, ...

The doughnut analogy also applies to distance: Because of the Milky Way's distance from Earth, looking at it from our planet is similar to seeing a doughnut on the surface of the Moon.

Caption. The distance between the Milky Way and Andromeda in 50 simulations. Just slightly more than half of orbits result in a Milky Way - Andromeda collision within 10 billion years.

The Milky Way and the neighboring Andromeda galaxy are currently hurtling through space toward each other at a speed of about 250,000 miles per hour (400,000 kph), setting up a possible future ...

They found that to find another galaxy just as outsized in its own wall as the Milky Way is, you'd have to travel 160–200 megaparsecs, or between around 521,600,000 and 652,000,000 light years.
