JACOBY 12,600 light-years Jacoby 1 is an ancient planetary nebula of exceedingly low surface brightness, ejected by an ultra-hot white dwarf star with a temperature of 140 000 degrees Kelvin on its exterior. Just discovered in 1995, this image may be the only colour view of Jacoby 1 to date. Credit: Mischa Schirmer. |
