Volans has several deep-sky objects within its borders. The Lindsay-Shapley ring, also categorized as AM0644-741, is a ring galaxy located 300 million light-years from Earth. Named for its discoverers, the Lindsay-Shapley ring was found near the Large Magellanic Cloud in 1960. Like theCartwheel Galaxy in Sculptor, the unusual shape of this galaxy results from a collision many millions of years ago. The blue ring, 150,000 light-years in diameter, was formed when a shock wave from the collision created a ring of hot blue stars; the yellow core is an amalgamation of the progenitors' cores.NGC 2442, an intermediate-spiral galaxy, is also located in this constellation, with a distance of 50 million light-years from Earth.<ref>[http://en.wikipedia.org/wiki/Volans Volans]</ref> | Volans has several deep-sky objects within its borders.

==Etymology== | |||
Volans, a fish flying, evokes the idea of a thing in a foreign environment; "a fish out of water" is a metaphor for something being out of its element; a stranger, exile, foreign. The Mediterranean flying fish is called Exocoetus exiliens, from Latin exilium, exsilium,'exile'. | |||
Volans is the present participle of volare, to fly, and comes from the Indo-European root *gwel- 'To fly; a wing'. Derivatives: volant (having wings), volatile (quickly evaporating; easily changing, fickle), vole2 (taking of all card tricks in card games), volitant (fly about, move swiftly), volley (a flight of missiles). <ref>[http://www.constellationsofwords.com/Constellations/Volans.htm Constellations of Words]</ref> | |||
