Intro and Visual description
Dorado the Swordfish is a small and obscure but very interesting constellation. It contains the Large Magellenic Cloud (LMC) and the only recent naked-eye supernova. In addition, the south ecliptic pole is located about where the "eye" of the fish would be. The Large and Small Magellenic Clouds are bright enough to be visible even in Moonlight.
The Magellenic clouds are satellite galaxies bubbled off of the Milky Way like spray from a fountain. However, some astronomers consider them galaxies in their own right (the LMC has a degree of spiral structure). These bright regions of light, observed by Ferdinand Magellan in 1519 and by other early explorers like Amerigo Vespucci and Marco Polo, are also known as Cape Clouds.
Origin and History
One of the eleven southern constellations created by Pieter Dirksz Keyser and Frederick de Houtman in 1596. These were published in Plate Aaa of Johann Bayer, Uranographia (1603).
