The Orion Nebula

The colorful Orion Nebula lies in our Milky Way galaxy about 1,500 light-years from Earth. A vast expanse of valleys and pillars carved through cosmic swirls of gas and dust, this stellar nursery encompasses a complete range of star formation. Images from NASA’s Hubble Space Telescope reveal thousands of developing stars scattered throughout the region. Deep inside the nebula, which spans about 15 light-years, cold and dense clouds of gas collapse under their own gravity. As each cloud contracts, its core compresses and heats until nuclear fusion ignites a new star. Over hundreds of thousands of years, newborn planetary systems arise from the dust and gas that wrap the stars with shadowy disks. The observations by Hubble provide scientists with a glimpse into how our sun and planets formed five billion years ago. Watch the video for a tour of the nebula.
