NGC 1788 (also known as the Bat Nebula as its structure is somewhat reminiscent of a bat) is a reflection nebula in the constellation Orion in the northern sky . He is in the sky only a few degrees of the belt stars of Orion and is about 3,000 light-years from the sun away
NGC 1788 is significantly influenced by the massive stars of the Orion region. The winds of these stars gave the nebula its shape, stimulated the formation of stars in it and also made the hydrogen gas glow (in the picture the reddish stripe on the left half of the picture).
Most of the stars that are in the nebula are obscured by dust. One of the few exceptions is HD 293815 . The stars in this region are very young, with an average age of one million years.
The object was discovered on February 1, 1786 by the German-British astronomer Friedrich Wilhelm Herschel .
