Collision or illusion?
The Hubble Space Telescope has captured this image of the spiral galaxy NGC 105, situated about 215 million light-years away in the constellation Pisces.
NGC 105 appears to be on a collision course with a neighbouring galaxy, but this is merely an illusion created by their alignment in our line of sight.
The elongated galaxy near NGC 105 is, in fact, much farther away and not well known to astronomers. Such deceptive conjunctions are common in astronomy. For example, the stars in constellations, while forming patterns from Earth's perspective, are actually at vastly different distances from us.
