'''NGC 3314''' is a pair of overlapping [[spiral galaxies]] between [[1 E22 m|117 and 140 million]] [[light-year]]s away in the [[constellation]] of [[Hydra (constellation)|Hydra]]. The very unique alignment of both [[Spiral galaxies]] gives [[astronomer]]s the opportunity to measure the properties of [[interstellar dust]] in the face-on foreground galaxy ('''NGC 3314a'''). The dust appears as dark blue against the background galaxy ('''NGC 3314b''').  Unlike [[interacting galaxies]], the two components of NGC 3314 are physically unrelated and are too distant from one another to interact. The galaxies {{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 of one of the galaxies. Astronomers theorized that it could have been a [[supernova]], but the unique filtering properties of the foreground galaxy made it difficult to decide definitively.<ref>{{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}}</ref>                                                                                                                                             
'''NGC 3314a''' is seen face-on as the '''foreground''' galaxy, its spiral arms and copious amounts of dust obscuring the '''background''' galaxy '''NGC 3314b'''. a dust tail can also be seen from NGC 3314a, being a sign of [[Ram Pressure]] stripping caused by NGC 3314a rushing through the [[intracluster medium|ICM]] of its home cluster, the [[Hydra Cluster]].
Both of the galaxies are members of the [[Hydra Cluster]].<ref name=":3">{{Cite journal|last=Richter|first=O.-G.|date=February 1989|title=The Hydra I cluster of galaxies.
