The Flower Nebula – Oil on canvas

40” x 40”

Based on a supernova remnant. So massive is the explosion that for a brief amount of time, the explosion actually outshines the entire galaxy in which it explodes

These are enormously big stars eventually explode shooting out matter in every possible direction. These ejected materials eventually form a nebula. The material that is expelled from the exploding star travels at a very high speed of 30,000 kilometers in one second.

This explosion sends out a shockwave in nearby outer space. The outer space that we keep saying is actually referred to as interstellar medium which is defined as matter that exists in space between stars within a galaxy. As this shockwave travels through this interstellar medium, the gas and dust from the exploding star are bound by the shockwave and it continues to expand. This expanding structure is known as supernova remnant.

Not every star explodes. For instance, our Sun (which is a star) will never explode. Stars that are 10 to 100 times bigger than our Sun eventually explode and create a supernova explosion

In essence, a nebula is formed when portions of the interstellar medium undergo gravitational collapse. Mutual gravitational attraction causes matter to clump together, forming regions of greater and greater density. From this, stars may form in the center of the collapsing material, who’s ultraviolet ionizing radiation causes the surrounding gas to become visible at optical wavelengths.

Most nebulae are vast in size, measuring up to hundreds of light years in diameter. Although denser than the space surrounding them, most nebulae are far less dense than any vacuum created in an Earthen environment. In fact, a nebular cloud that was similar in size to Earth would only so much material that its mass would be only a few kilograms.
