The Ghost Nebula

With Halloween only a few days away, now’s a good time to take a look at The Ghost Nebula in the constellation Cepheus. It’s a giant cloud of dust two light years across and some 1,200 light years away.

The weird shape is made visible by dust that reflects the light of several stars buried within the nebula. The sepia tones are the result of starlight streaming through the fine dust, with the blues and violets of the stars’ light scattered away, leaving only the warmer yellows to reach our eyes.
