Description

IC 2118 is a reflection nebula in the Orion constellation, around 900 light years from earth.

It’s essentially a large cloud of dust that’s being illuminated by starlight. As such, the colours/tones that we perceive will be largely dependent on the nearby stars. As you can see, there’s a fairly dominant blue’ish tone present. That’s because the nebula is right next to (astronomically speaking) the blue supergiant star Rigel; one of the brightest stars in our night sky and one you’ve no doubt seen before (it makes up the “left leg” of the hunter figure in the Orion constellation).
