Who Are You Calling an Irregular Dwarf?

ESA/Hubble & NASA ; Acknowledgement: Judy Schmidt (Geckzilla)

Tuesday, March 29, 2016: Irregular dwarf galaxy UGC 4459 lies approximately 11 million light-years away in the constellation of Ursa Major (The Great Bear). Irregular dwarf galaxies often possess a chaotic appearance, with neither a nuclear bulge in the center nor spiral arms extending outwards. Owing to their low masses, these galaxies generate fewer stars than larger galaxies. Image released March 28, 2016.

Cosmic Dust

Canada-France-Hawaii Telescope/Coelum

Thursday, March 31, 2016: Dark regions of space in nebula LBN 468 appear devoid of stars, but the dark patches actually consist of dust obscuring stars that lie beyond. This dust arises from elements in molecular clouds, such as carbon and silicon, combining into tiny particles. Image released March 2016.
