The Trifid Nebula in Stars and Dust

                          

 Unspeakable beauty and unimaginable bedlam can be found together in theTrifid Nebula. Also known as M20, this photogenic nebula is visible with good binoculars towards the constellation of Sagittarius. The energetic processes of star formation create not only the colors but the chaos. The red-glowing gas results from high-energy starlight striking interstellar hydrogen gas. The dark dust filaments that lace M20 were created in the atmospheres of cool giant stars and in the debris from supernovae explosions. Which bright young stars light up the blue reflection nebula is still being investigated. The light from M20 we see today left perhaps 3,000 years ago, although the exact distance remains unknown. Light takes about 50 years to cross M20.

Space art

Space art is a general term for art emerging from knowledge and ideas associated with outer space, both as a source of inspiration and as a means for visualizing and promoting space travel. Whatever the stylistic path, the artist is generally attempting to communicate ideas somehow related to space, often including appreciation of the infinite variety and vastness which surrounds us. In some cases, artists who consider themselves space artists use more than illustration and painting to communicate scientific discoveries or works depicting space; a new breed of space artists work directly with space flight technology and scientists as an opportunity to expand the arts, humanities and cultural expression relative to space exploration.
