Nebulas are mesmerizing giants, and their soft colors invite you to dive into their vastness and get lost in your deepest dreams. Beware, however, the deceiving beauty of their gentle appearance: many nebulas  originate from the violent death of a star. Others emerge when diffuse interstellar gas cools down and condensated forming enormous clouds with curious shapes that glow illuminated by countless stars. The gravitational pull in their densest regions collapses the cloud and breeds a myriad of new bright stars.
