Along the Taurus Molecular Cloud Image Credit & [3]Copyright: [4]Yuexiao Shen, Joe Hua Explanation: The cosmic brush of star formation composed [5]this interstellar canvas of emission, dust, and dark nebulae. A 5 degree wide telescopic mosaic, it frames a region found north of bright star Aldebaran on the sky, at an inner wall of [6]the local bubble along the [7]Taurus molecular cloud. At lower left, emission cataloged as [8]Sh2-239 shows signs of embedded young stellar objects. The region's Herbig-Haro objects, nebulosities associated with newly born stars, are marked by tell-tale reddish jets of shocked hydrogen gas. Above and right T Tauri, the prototype of the class of [9]T Tauri variable stars, is next to a yellowish nebula historically known as Hind's Variable Nebula ([10]NGC 1555). T Tauri stars are now generally recognized as young, less than a few million years old, sun-like stars still in the early [11]stages of formation.
