... At magnitude -19.36, Sol would still look brighter than the full moon seen from Earth as seen from Neptune. It would obviously cast shadows, and would scatter light in Neptune’s cloudtops so that the sky would probably be a deep blue as seen by a viewer sitting in the planet’s upper atmosphere. Next ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
