Irregular Galaxies

Description
Irregular Galaxies
(a) At a distance of only 179,000 ly, the Large Magellanic Cloud (LMC), an Irr I irregular galaxy, is passing close to our Milky Way Galaxy.
About 62,000 ly across, the LMC spans 22° across the sky, about 44 times the angular size of the full Moon. Note the huge H II region
(called the Tarantula Nebula or 30 Doradus). Its diameter of 800 ly and mass of 5 million solar masses make it the largest known H II region.
