This is part of the Centaurus constellation which is located in the southern sky visibly referenced around the Southern Cross. Its stars are some of the brightest visible and some of the closest. This particular image is a stacked image of several forms of light so as not to be obscured by interfering space dust left over from the collision of the contributing galaxies.
The result is small, ‘young’ blue stars and a hard to imagine gigantic molecular jumble. That and a cool background image.
