Astronomers identify twelve new Herbig-Haro objects in the dark nebula LDN 673

(Phys.org)—Astronomers have found a dozen new faint Herbig-Haro objects in the dark nebula LDN 673 by employing a novel color-composite imaging method. The discovery, reported in a paper published December 1 on the arXiv pre-print server, could provide new important information about star formation process.
