Astronomers have used the youngest objects in the Milky Way to build a new map of the galaxy's spiral arms, and the results are far messier than expected.

In the vast expanse of the universe, the Milky Way Galaxy holds a special place in our hearts. It is our home, and after studying it for decades from our cosmic residence nestled within one of its ...

Stargazers may catch a cosmic light show this Fourth of July weekend when the Milky Way appears in the night sky across the ...

This artist's concept illustrates the new view of the Milky Way. The galaxy's two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two ...

Galaxies come in an array of shapes. Some, like the Milky Way, are composed of arms of well-ordered stars revolving in a spiral shape around a central concentration or "bulge" of stellar bodies.

New paper links formation of Earth’s continents to solar system’s passage through dense interstellar clouds within our Milky Way’s four spiral arms.

In 2008, the Milky Way lost two of its four major spiral arms, according to some analyses. But the galaxy may be getting them back. Radio telescope data from the 1950s first suggested that the ...

More commonly, however, the spirals split to form other minor arms, probably as a result of collisions and mergers with other clusters and galaxies. On top of this, some spirals have a central bulge ...

The vast, spiralling arms of our Milky Way galaxy could have helped form the continents that we live on today, according to a new study.. The Earth’s continental crusts appear to undergo periods ...

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

Large spiral galaxies like the Milky Way were thought to take several billion years to form. Thus, during the first billion years of cosmic history, scientists expected to observe only small ...
