Here’s a new breathtaking view of the Lagoon Nebula. The region is filled with intense winds from hot stars, funnels of gas, and energetic star formation, all embedded within pitch-dark dust.

This map illustrates the Copernican system of the Universe, as described by Copernicus in his “De Revolutionibus Orbium Coelestium” (On the Revolutions of the Celestial Spheres), published in 1543. His Heliocentric model, with the Sun at the center of the Universe, demonstrated that the observed motions of Celestial objects can be explained without putting Earth at rest in the center of the Universe. His work spurred further scientific investigations, becoming a landmark in the history of Science that is often referred to as the Copernican Revolution.
