ASTRONOMY PHOTO OF THE DAY: The Red Rectangle Nebula. Credit: ESA, Hubble, NASA. The Red Rectangle nebula lies 2,300 light years towards the constellation of the Unicorn (Monoceros). At its centre is an aging binary star system that powers the nebula. The unusual shape is likely due to a thick dust torus which pinches the otherwise spherical outflow into tip-touching cone shapes, with the outflow occurring in fits and starts. In a few million years, as one of the central stars becomes further depleted of nuclear fuel, it will likely bloom into a planetary nebula.

On 30 June 1911, less than a year after the downfall of the constitutional monarchy, this design was officially adopted.
