Orion Nebula: The heart of the Artwork
An image from NASA’s Spitzer and Hubble Space Telescopes looks more like an abstract painting than a cosmic snapshot. The magnificent masterpiece shows the Orion nebula in an explosion of infrared, ultraviolet and visible-light colors. It was “painted” by hundreds of baby stars on a canvas of gas and dust, with intense ultraviolet light and strong stellar winds as brushes.
At the heart of the artwork is a set of four monstrously massive stars, collectively called the Trapezium. These behemoths are approximately 100,000 times brighter than our sun. Their community can be identified as the yellow smudge near the center of the composite.
Additional stars in Orion are sprinkled throughout the image in a rainbow of colors. Spitzer exposed infant stars deeply embedded in a cocoon of dust and gas (orange-yellow dots). Hubble found less embedded stars (specks of green) and stars in the foreground (blue). Stellar winds from clusters of newborn stars scattered throughout the cloud etched all of the well-defined ridges and cavities.
