Using a powerful Gemini South telescope in Chile, two Argentine astronomers Julia Arias and Rodolfo Barbá captured this dramatic and colorful image that shows newly born stars embedded in thick clouds in the beautiful Lagoon nebula, located in the Sagittarius constellation in the southern Milky Way.

The Argentine astronomers are studying Herbig-Haro (HH) objects — small patches of nebulosity associated with newly born stars which are formed when gas ejected by young stars collides with clouds of gas and dust nearby at speeds of several hundred kilometres per second. Herbig–Haro objects are ubiquitous in star-forming regions, and several are often seen around a single star, aligned along its rotational axis.
HH objects are transient (in Universe time, that is) phenomena, lasting not more than a few thousand years.

  1. Kinda looks like an oil slick. Geeze, I hope the dems don’t find out about – they won’t issue any new star permits.
