Hubble's Variable Nebula (NGC 2261) - Named for American astronomer Edwin P Hubble, this nebula is lit by the star R Monocerotis, bottom of nebula, in the constellation Monoceros (Greek : unicorn). There is probably a symmetrical counterpart of the fan-shape on the southern side of the star, but it is heavily obscured from view by dust lying between this lobe and our line of sight
