NGC 3314 is a pair of overlapping spiral galaxies between 117 and 140 million light-years away in the constellation Hydra. This unique alignment gives astronomers the opportunity to measure the properties of interstellar dust in the face-on foreground galaxy (NGC 3314a). The dust appears dark against the background galaxy (NGC 3314b). Unlike interacting galaxies, the two components of NGC 3314 are physically unrelated. It{{Clarify|date=February 2022}} was discovered in April 1999.

In a March 2000 observation of the galaxies, a prominent green star-like object was seen in one of the arms. Astronomers theorized that it could have been a supernova, but the unique filtering properties of the foreground galaxy made it difficult to decide definitively.{{Cite web|title = NGC 3314 Variable Object|url = http://heritage.stsci.edu/2000/14/blink.html|website = heritage.stsci.edu|access-date = 2015-11-05|last = Keel|first = Bill|last2 = Frattare|first2 = Lisa}}
