| The Sagittarius Star Field is a cloud of stars located some 25,000 light years away toward the constellation Sagittarius. The constellation Sagittarius occurs toward the center of the Milky Way galaxy, where the stars are especially concentrated. Most views of the center of the galaxy are blocked by obscuring dust, but this particular region is relatively free of dust, allowing for an unobstructed view. The color of a star is directly related to its temperature, mass, and age. Blue stars are hot, of high mass, and young, whereas red stars are cool, of low mass, and old. Yellow stars like the Sun are of intermediate temperature, mass, and age. |
