A Cometary Globule Reaching for the Stars | Victor Blanco Telescope

A Cometary Globule Reaching for the Stars | Victor Blanco Telescope

Cosmoview Episode 81: This cloudy, ominous structure is CG 4, a cometary globule nicknamed ‘God’s Hand’. CG 4 is one of many cometary globules present within the Milky Way, and how these objects get their distinct form is still a matter of debate among astronomers. This image was captured by the Department of Energy-fabricated Dark Energy Camera on the U.S. National Science Foundation VĂ­ctor M. Blanco  Telescope at Cerro Tololo Inter-American Observatory, a Program of the National Science Foundation's NOIRLab. In it, the features that classify CG 4 as a cometary globule are hard to miss. Its dusty head and long, faint tail vaguely resemble the appearance of a comet, though they have nothing in common. Astronomers theorize that cometary globules get their structure from the stellar winds of nearby hot, massive stars.
