Andromeda Galaxy -- The most famous of all galaxies is also the most distant object visible to the naked eye, and the nearest major galaxy to our Milky Way. In some ways its spiral structure resembles that of our own galaxy, but it is about twice as massive. The galaxy is most visible in the northern sky towards the end of autumn and beginning of winter. Andromeda's proximity will be deadly to our galaxy. Astronomers estimate that it will collide with the Milky Way in about 5 billion years.
The Cartwheel galaxy as seen by 3 space telescopes. 100 million years ago, another, smaller galaxy tumbled through the Cartwheel galaxy and left behind "ripples" of star creation. The outer ring is the first ripple, with high ultraviolet output, and the inner yellow spot is from the second ripple, which was smaller and high in infrared output.
