hubble and planetary nebulae - photo #20
{"Image ImageDescription": "The NASA/ESAHubble Space Telescope has shown us that the shrouds of gas surrounding dying, sunlike stars (called planetary nebulae) come in a variety of strange shapes, from an 'hourglass' to a 'butterfly' to a 'stingray.' With this image of NGC 6210, the Hubble telescope has added another bizarre form to the rogues  gallery of planetary nebulae: a turtle swallowing a seashell. Giving this dying star such a weird name is less of a challenge than trying to figure out how dying stars create these unusual shapes."}
