Kronberger 61, also known as the "soccer ball", is a planetary nebula discovered by an amateur astronomer in January, 2011, with the newer images having been taken by the Gemini Observatory.[2] The nebula is named for Austrian Mattias Kronberger,[3] who is a member of the amateur group Deep Sky Hunters. The object is estimated to lie 13,000 light-years away. They discovered the nebula while searching near the northern constellation of Cygnus.[4] It is hoped that the discovery will help resolve a decades-old debate, regarding the role of stellar companions in the formation and structure of planetary nebulae.[5]
