The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter. It is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is Read More …
