Visible in small telescopes, the nebula lies near Wasat (Delta Geminorum), between Kappa and Lambda Geminorum. The X-rays were produced by a jet launched from the core of the star at the moment of its collapse. Because Type Ia supernovae arise from dim, common white dwarf stars, it is likely that a supernova that could affect the Earth will occur unpredictably and take place in a star system that is not well studied. Why do people smile when talking about trauma? For Pollux to go supernova, it would have to be of much bigger mass. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. "It suggests that planet-formation around stars much more massive than the sun may [be] common," read an Astronomy and Astrophysics paper concerning the discovery. NY 10036.
