Today, astronomers have measured the distance to the Andromeda Galaxy much more precisely; they find it to be about 2 1/2 million light years away. It is a majestic spiral-shaped galaxy ...

The Andromeda galaxy is a colossal marvel in our sky, hosting over 1 trillion stars. Now, astronomers have used the Hubble Space Telescope to capture hundreds of detailed images of our vast galactic ...

His remark holds true now, nearly half a decade later. At 2.5 million light-years away, the Andromeda Galaxy—officially called Messier 31—is the farthest object visible to the naked eye.

In addition, this representative map of the line-of-sight velocities allowed the team ... and what effect they have had on the galaxy. Andromeda clearly has had a more active merger history than the ...

Andromeda is the closest large galaxy to the Milky Way. And it is getting closer, as the two will merge in several billion years. It has been an object of study for centuries, but we have never seen ...

The Hubble Space Telescope has produced the most comprehensive survey of the Andromeda galaxy, revealing new clues about its history. The Hubble survey, assembled from over 1,000 orbits and ...

(NASA/ESA/Williams/Univ. of Wash. via SWNS) By Dean Murray A jaw-dropping new panorama of Andromeda galaxy took 10 years to create. The largest photomosaic of the cosmic wonder was assembled from ...

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 ...

This illustration shows a stage in the predicted merger between our Milky Way galaxy and the ... [+] neighboring Andromeda galaxy, as it will unfold over the next several billion years.

Messier 32 resembles the stripped-down core of an ex-spiral galaxy in the nearby vicinity, suggesting the two may have had a coming together in the distant past. Weisz continues: “Andromeda ...
