Beginning in the months of Autumn, the Orionid meteor shower sends streaks of light across the heavens. Peaking around October 21, the yearly display comes from icy remnants of Halley鈥檚 Comet drifting in the path of our planet鈥檚 orbit and appears to Earth observers to come from the constellation of Orion.
Orion is named for a mythological Greek hunter, though many ancient cultures from Babylon to China have names for this grouping of stars. The oldest depiction of Orion found to date is a 32,000-year-old carved mammoth tusk found in Germany.
Orion the hunter is one of the most beloved constellations, known even to the most occasional stargazer. Located along the celestial equator, Orion is best seen in the evenings, January to March, during the Northern Hemisphere鈥檚 winter and the Southern Hemisphere鈥檚 summer. But the only time it鈥檚 truly out of reach is from May to July when it鈥檚 visible during midday 鈥 unless you鈥檙e in Antarctica, of course.
As you鈥檙e training your gaze on the mighty hunter Orion, peer a little deeper and uncover the stars and deep-sky objects that make up this iconic constellation. Enjoy delicate swirls and brilliant colors of Orion鈥檚 most beautiful nebulae.

Orion Nebula
Found south of Orion鈥檚 Belt, the titular nebula is one of the most heavily studied nebulae in the night sky. With a telescope, you can see filaments of gas and dust, as well as the dense masses of star-forming regions within the nebula.

Running Man Nebula
This reflection nebula is part of a larger region of ionized gas that makes up the northernmost part of Orion鈥檚 sword. It lies near the Orion nebula 鈥 look for the characteristic outline of a figure with arms and legs splayed outward, hidden inside the gas cloud.

Horsehead Nebula
Astronomer听听first discovered this equine-shaped object in 1888. Cataloged as Barnard 33, the dark nebula is full of shadowy dust with newly-formed stars visible at its base.

Flame Nebula
The Flame Nebula (also known as NGC 2024) is an emission nebula, which means it鈥檚 full of ionized gases that emit light. It actually gets many of its colors thanks to Alnitak, the easternmost star is Orion鈥檚 belt, whose UV light causes the nebula to glow brightly.

Messier 78
NGC 2068 or M78 is a reflection nebula just northwest of Alnitak that鈥檚 1,350 light-years from Earth. French astronomer Pierre M茅chain discovered it in 1780.

Monkey Head Nebula
NGC 2174 is another emission nebula found in the constellation Orion that resides 6,400 light-years away. Be sure to try and spot the 鈥渕onkey鈥檚 head.鈥

Cosmic Bat Nebula
This nebula, also known as听, is a reflection nebula that scatters the light from most of the stars within, obscuring them with its dust and gas. In a dark corner of the Orion constellation, this elusive object is home to a number of infant stars.
