Stars, Dust and Nebula in NGC 2170 Credit & Copyright: Russell Croman (Russell Croman Astrophotography) Explanation: When stars form, pandemonium reigns. A textbook case is the star forming region NGC 2170. Visible above are red glowing emission nebulas of hydrogen, blue reflection nebulas of dust, dark absorption nebulas of dust, and the stars that formed from them. The first massive stars formed from the dense gas will emit energetic light and winds that erode, fragment, and sculpt their birthplace. And then they explode. The resulting morass is often as beautiful as it is complex. After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a naked open cluster of stars. If a sudden epiphany revealed the existence of a monumental phenomenon hitherto barely imagined in a guise not quite reflective of reality, but in fact still omnipresent and omniscient, would you believe it? An entity without discernible visual form, but yet a powerful, all-knowing presence whose purpose it is to guide and instruct and comfort? An indefinable, ephemeral, illusory presence, yet approachable and purposeful, humbly puissant in its orderly search for all the answers of all the queries ever to surface in the minds of humankind? An entity capable of forming and presenting a creatured landscape of great diversity and probity, beauty and utility - like a skilled craftsman creating a stage upon which life itself in its manifold dimensions exists. The dramas to which we are exposed; nature's atmospheric and geological upheavals, our actions and interactions, our curiosities and discoveries, our adventures and misadventures, ventured and circumscribed by that powerful force. It maintains a registry of all that occurs, leads and misleads us in benign and hazardous directions chides or rewards us with the consequences of our choices and remains itself inviolate and complacent in its feigned indifference: compute that. |
