In the event you look due South after astronomical twilight (and hour and a half after sundown) in a darkish sky location you will note what appears to be like like two wispy clouds however not like clouds they don’t transfer, these are the Magellanic clouds, the dwarf companion galaxies to ours. The most important of the wisps, to the left of due south is the big Magellanic cloud. The Giant Magellanic cloud lies at an approximate distance of 163,000 gentle years from us. The LMC has a outstanding bar in its central area, which signifies that it might have beforehand been a barred spiral galaxy.

A line by means of Sirius and Canopus carried on will piece the center of the LMC. Throughout the hazy disk of the LMC is a fuzzy star, that is the tarantula nebula.
