Orione's constellation is a very rich one as well:its main star is called Betelgeuse, which means "the shoulder" in Arabian, and which is none less than 400 times bigger than our Sun.
Another stunning object in the constellation is the nebulas M 42, in the so called "knife's" of Orione.
Orione's constellation is also surrounded by interesting other ones as Unicorn, Major and Minor Dog and it's near also to the Rosette Nebula, code name NGC 2244, which is actively producing gases destined to be a nursery for new stars.
Also the Scorpio constellation is a source of delight for the eyes:the alpha star there is called Antares, whose diameters is 700 times (!!) that one of our Sun. If instead of Sun we had in the Solar System Antares, well Mercury, Venus, the Earth and Mars would have been taken into the body of the star itself.
Antares name derives from its wonderful red colour, which was making it rival under the eyes of Greeks with Ares planet (Mars), coloured in red as well, and from that it came the name: "anti ares", against Ares, therefore Antares.
