A spectrum unravels the light and enables more detailed research on the nebula’s composition, temperature, density, and velocity of the gas. Astronomers separated the light from the nebula into its component colors, creating a spectrum to study the nebula’s properties. The image shows structural information, but it cannot identify which elements are the source of the light. ![]() The multicolor image is a composite created by combining the four single-color images. This may have happened repeatedly, creating the multiple pairs of hourglasses. ![]() These winds rammed into and displaced much slower gas upstream, pushing it into the edges of the hourglass lobes that we see today. The winds moved at speeds of hundreds of miles per second through a pair of cone-like openings, like rocket exhaust. The nebula appears to have three, nested, hourglass shapes that were likely sculpted by dense winds from a red giant star as it and a white dwarf whirled around one another in a close orbit. Scientists turned the Hubble Space Telescope toward the Southern Crab Nebula to learn about its complicated structures. ![]() These data reveal important details about the makeup of atmospheres of exoplanets, the temperatures of stars and nebulae, the motion of galaxies, and more. By examining the intensity of light, or lack thereof, in each color, scientists can work backward to infer the properties of the material that left their stamp on the observed rainbow. This “stamp” is like a fingerprint for each element and molecule. When materials interact with light or emit their own light, properties of that material are stamped on the light. Light is packed with information! By using specialized instruments on telescopes, researchers can spread out light into a rainbow (known as a spectrum) to analyze its properties and learn about objects in the universe. By using spectra to unravel light, scientists learn more than they can from a picture alone. ![]()
