... above the horizon at sunset so observe Saturn as soon as you can this month, in the south-west. Uranus is at opposition on the 15th and is visible throughout the night this month. At a magnitude of 5.70 it may well be seen with binoculars. A small telescope might show a blue hue, but since Uranus us ...

Cygnus the Swan, Leo the Lion and Orion the Hunter are perhaps exceptions and do (with a little imagination) look remotely like those characters. The stars making up the constellations are not generally physically associate ...

For instance, there are many more stellar classes than OBAFGKM; however for simplicity’s sake, only the classes that contain a large majority are shown. Absolute magnitude – the intrinsic brightness of stars – is similar ...
