    StDr20 is the potential remnant of a dying star, a planetary nebula in the constellation Puppis, at a distance of nearly 4000 light-years from Earth. The probable PN has not yet been spectroscopically confirmed, but there is no doubt about the nature of a PN.

    StDr20 (Aurore's Nebula) was discovered in February 2020 by Xavier Strottner and Marcel Drechsler of the team "StDr".

    StDr20 is extremely old, because it is very distant, extremely faint, but still 6' arcminutes large.
    Estimated age about 20000 years.
