Astronomers have determined that the Milky Way's outer halo is filled with "magnetic donuts" that are as wide as 100,000 light-years. The discovery could shed light on how cosmic magnetic fields ...

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 recent discovery of a magnetic halo surrounding the Milky Way galaxy could significantly alter our understanding of galactic evolution. Researchers from the National Institute for Astrophysics ...

Previous studies of the Milky Way's inner halo — the region surrounding the galaxy's familiar spiral-armed disk — had estimated that it formed anywhere between 10 and 13 billion years ago. The ...

The team spotted the stars in the Milky Way's "halo"—the cloud of stars that envelopes the entire main galactic disk. Based on the team's analysis, the three stars formed between 12 and 13 ...

The Milky Way is home to gas, dust, billions of stars, and a supermassive black hole at its center. Living in this galactic home gives us exclusive insight into its components, but it also hinders ...

Around the Milky Way, there is a region with a diffuse population of stars known as the halo. It is much bigger than the disk where the spiral arms, including the one with our Solar System in it ...

We are not alone—at least as a galaxy. About 50 dwarf galaxies surround the Milky Way.But when its intense gravity inevitably draws them to venture too close, they will probably be annihilated.

Astronomers have detected in the stellar halo that represents the Milky Way's outer limits a group of stars more distant from Earth than any known within our own galaxy - almost halfway to a ...

The Milky Way’s halo is a cloud of stars that encompass all of our galaxy’s main galactic disk. The team believes that these three stars formed between 12 and 13 billion years ago, ...

The Milky Way's core will be visible this month and through August. Here's what Tennessee stargazers should know.

Astronomers have at last identified what’s believed to be the edge of the Milky Way galaxy. A team of astronomers from England used that farthest point to determine that the diameter of the ...
