Zeta Ophiuchus, a massive star plowing through the gas and dust floating in space. Zeta Oph is a bruiser, with 20 times the Sun’s mass. It’s an incredibly luminous star, blasting out light at a rate 80,000 times higher than the Sun. Looks remarkably like a bow.
The breathtakingly beautiful Cocoon Nebula is located about 4,000 light years away toward the constellation of Cygnus. Hidden inside the Cocoon is a newly developing open cluster of stars dominated by a massive star in the center of the above image that opened a hole in an existing molecular cloud through which much of the glowing material flows. The same star, which formed about 100,000 years ago, provides the energy source for much of the emitted and reflected light from this nebula.
