Measuring colour in astronomy
... Many of the galaxies imaged by SDSS are too far away to make out individual features, so one has to measure the spectrum and colour of a whole galaxy. Since the light from a galaxy is just the sum of all the light from the individual stars of which it is made, its spectrum – and hence its colour – i ...

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.
