What will happen to the solar system when the Milky Way completes the merger with the Andromeda Galaxy? Bryan ...

The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

About 100 years after astronomer Edwin Hubble's discovered the "magnificent" spiral nebula, the Hubble Space Telescope and NASA scientists have produced the most comprehensive survey of the Andromeda ...

Astronomers spent a decade compiling this special image with the Hubble Space Telescope and then stitched together 600 photos to showcase over 200 million stars.

This image of the Andromeda Galaxy, captured by the Herschel Space Observatory, reveals a detailed view of cool lanes of star formation.

In about 4.5 billion years, the Andromeda Galaxy will collide with the Milky Way, resulting in a spectacular cosmic collision! Don’t worry, though – the distances between stars are vast ...

But only one galaxy stands out as the most important nearby stellar island to our Milky Way -- the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear ...

The astronomical panorama is a major accomplishment because Andromeda is the “closest” large galaxy to ours, at a distance of 2.5 million light years away—equal to the diameter of the Milky Way disk ...

But only one galaxy stands out as the most important nearby stellar island to our Milky Way—the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear ...

Observations show Andromeda has a more active star formation history than the Milky Way, potentially due to a past galactic collision. NASA recently released images of the Andromeda galaxy ...
