Hubble Reveals the Ring Nebula's True Shape
In this composite image, visible-light observations by NASA's Hubble Space Telescope are combined with infrared data from the ground-based Large Binocular Telescope in Arizona to assemble a dramatic view of the well-known Ring Nebula. Called a planetary nebula, the Ring Nebula...
Hubble Captures a Ring
This close-up, visible-light view by NASA's Hubble Space Telescope reveals new details of the Ring Nebula. The object is tilted toward Earth so that astronomers see the ring face-on. The Hubble observations reveal that the nebula's shape is more complicated than astronomers...
