The photo shown was taken by the Hubble Space Telescope. Astronomers describe it as representing the life cycle of stars. The bright blue area on the upper left is a blue supergiant, which is a dying star. Sugergiants are very bright and have a diameter over 100 times that of the Sun.
The golden region with spots of stars is an open cluster of stars, which are young stars in a group of less than a few hundred. These stars are bound to each other by their gravity.
These monstrous pillar-like structures are actually columns of cool hydrogen gas and dust. To some they look like giant stalagmites on a cavern floor.
Clouds of gas and dust in space are called nebulae, which are the starting materials for new stars. These clouds are part of the Eagle Nebula 7,000 light-years from Earth.
