Text, Cosmic Tour, The Horsehead Nebula
Sixteen hundred light-years away, a shadowy cloud of gas and dust - the Horsehead Nebula - juts out into a starlet void. Scale bar showing 1 light-year 0.31 parsecs
The nebula is illuminated by a young, multiple-star system above the image.
The harsh stellar winds and ultraviolet radiation emitted by one of the young stars is slowly eroding the nebula, exposing newly-formed stars embedded within it.
