This spectacular image from the NASA/ESA Hubble Space Telescope captures the spiral galaxy NGC 105, which lies roughly 215 million light-years away in the constellation Pisces. While it looks like NGC 105 is plunging edge-on into a neighboring galaxy, this is just a circumstance of perspective. NGC 105's elongated neighbor is actually far more distant. Such visual associations are the result of our Earthly perspective and they occur frequently in astronomy. A good example of this are the constellations. The stars that form constellations are at vastly different distances from Earth. To us they appear to form these patterns because they are aligned along the same sightline, while an observer in another part of the galaxy would see different patterns.
