Reposted from @space_telescopes ・・・ Irregular galaxies have—you guessed it—no specific form, but there are two types. The first is often a single galaxy with an unusual appearance (in other words, it’s still gorgeous, but not symmetrical). The second is more interesting. This type of irregular galaxy may interact with or disrupt other galaxies through collisions or mergers, and contain a large amount of dust, making it extraordinarily interesting to study. Hubble imaged NGC 1569, which has pumped out stars at a rate that is 100 times faster than the Milky Way for the past 100 million years. #astrodefinition Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA).
