Blue Horse Nebula
Blue Horse Nebula is a reflection nebula located about 400
light-years from Earth. Stretching about 20 light-years in length, it
is part of the larger Rho Ophiuchi complex of reflection and emission
nebula. IC4592 consists mostly of dust particles and is illuminated by
bright star Nu Scorpii, seen at the center-left as the horse's
eye. Part of another reflection nebula, IC4601, surrounds the
bright star at the top-right corner. North
is at the bottom.
