A beautiful view of Rho Ophiuchi in Ophiuchus constellation with Blue Horsehead nebula
Engraving of \
Comet C/ 2017 K 2 Pan STARRS passing by the Blue Horsehead Nebula in the constellation Scorpius. \nAn upside down horse head encounters a visitor from far far away as seen from earth. \nThe comet was relatively close at the time-17 light minutes from us- about twice as far as the sun roughly speaking - while the Blue Horsehead nebula is 400 light YEARS distant.\n\n Comet C/2017 K2 (PanSTARRS) had been traveling from the Oort cloud for some 3 million years in a hyperbolic orbit around our sun.\n\nIts nucleus is about 18 km or so in diameter;  its cometary atmosphere  (“coma”) is about 130,000 km in diameter, and its tail – clearly visible in this image -is estimated at 800, 000 km !\nThe Blue Horsehead – upside down* in this image because this was imaged from the Southern Hemisphere, from a dark site near Sydney last Sunday is a “reflection nebula”; so called because these nebulas are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars. In this case, the source of much of the reflected light is a star at the “eye” of the horse.

It is home to the hottest, most massive stars known!\n\nNicknamed the Tarantula Nebula for the appearance of its dusty filaments in telescope images, the nebula has long been a favorite for amateur astronomers.
