Feild and R. van der Marel, STScI Sometime in the far distant future, about 4 billion years from now, our Milky Waygalaxy will collide with the neighboring Andromeda galaxy, as illustrated in this artist’s […]

“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth,” says Professor Anders Johansen.

When most of us picture the shape of the Milky Way, the galaxy that contains our own sun and hundreds of billions of other stars, we think of a central mass surrounded by a flat disc of stars that spiral around it. However, astronomers know that rather than being symmetrical, the […]

The Milky Way houses 8,292 recently discovered stellar streams — all named Theia. But Theia 456 is special. A stellar stream […]

Scientists from Cardiff University have helped produce a brand-new, three-dimensional survey of our galaxy, allowing them to […]

Position and velocity map of the Milky Way Galaxy. Arrows show position and velocity data for the 224 objects used to model the Milky Way Galaxy. The solid black lines show the positions of the Galaxy’s spiral arms. The colors indicate groups of objects belonging the same arm. The background […]

The long-held belief that the Milky Way, the galaxy containing Earth and the solar system, is relatively static has been ruptured by fresh cosmic insight. The spiral-shaped disc of stars and planets is being pulled, twisted and deformed with extreme violence by the gravitational force of a smaller galaxy – the […]
