A new image combining previously released data from three telescopes shows a region that includes the Orion Nebula, named after the mighty hunter from Greek mythology who was felled by a scorpion’s sting. But the story of how this dusty region came to be is just as dramatic.

The Orion Nebula is located in the constellation Orion, which takes the appearance of a hunter raising a club and shield at an unseen target. Three stars in a line are together known as Orion’s belt; the region shown in the image aligns with another series of stars perpendicular to the belt, known as Orion’s sword. If you could see it in the sky, the region would appear about the size of the full moon.

Two enormous caverns that dominate the cloud were carved out by giant stars (unseen in this image) that can release up to a million times more light than our Sun. All that radiation breaks apart dust grains there, helping to create the pair of cavities. Much of the remaining dust is swept away by winds from stars or when the stars die explosive deaths as supernovae.

The blue light in these areas indicates warm dust. Observed in infrared light – a range of wavelengths outside what human eyes can detect – the views were provided by NASA’s retired Spitzer Space Telescope and the Wide-Field Infrared Survey Explorer (WISE), which now operates under the moniker NEOWISE. Spitzer and WISE were both managed by NASA’s Jet Propulsion Laboratory in Southern California.
