Hold the map face down above your head, and the cardinal points will be oriented as usual. As a starting point, face North, holding the map in your eyesight direction, with its ...

... a star completely of its outer layers, removing about half of its mass and exposing the hot core. Figure 3 shows two examples of planetary nebulae. The outer layers, illuminated by intense UV light from the core and glowing via fluorescence, form “planetary nebulae.” These nebulae have nothing to do ...
