The constellation of Scorpius is a large and includes many bright stars, that of the lower half of body is bathed in the summer's Milky Way.
The asterism of a vast skewed shape of "S" was taken an attention in many ancient cultures, for an example, it was regarded as a gigantic fishhook in Japanese fishing villages. Alpha Scorpii is well known as Antares meaning of "Rival of Mars", emitting pale red light at the heart of Scorpion. The star is considered as a supergiant and estimated to be about 230 sun diameters. It's about 600 light years away. To image of Scorpius with closed Mars |
