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.

While 2.5 million light-years away, the Andromeda galaxy can be visible to the naked eye on clear autumn nights. But the Hubble Telescope can see it even more sharply from space without the ...

"It's like photographing a beach and resolving individual grains of sand." Astronomers announced last week that they had completed a decade-long, meticulous effort to assemble a full portrait of ...
