Gemini Image Captures Elegant Beauty of Planetary Nebula Discovered by Amateur Astronomer
Gemini Observatory image of Kronberger 61 showing the ionized shell of expelled gas resembling a soccer ball. The light of the nebula is primarily due to ionized oxygen (oxygen-III) emission and its central star can be seen as the slightly bluer star very close to the center of the nebula. The field of view is 2.2 x 3.4 arcminutes with north up (rotated 22 degrees west of north). Image processing by Travis Rector, University of Alaska Anchorage. A color composite image, it consists of two narrow-band images (O-III and Hydrogen-alpha with three, 500-second integrations each) obtained with the Gemini Multi-Object Spectrograph (GMOS) on the Gemini North telescope on Mauna Kea in Hawaiâi. Below the bright star at left is a barred spiral galaxy in the distant background, careful inspection will reveal several additional distant galaxies in the image.
