Starlight Reflections
28.12.2001

Interstellar dust grains often find themselves in a reflective "mood". Near a bright star, clouds of these dust particles scatter short wavelengths of visible starlight more readily than long wavelengths, producing lovely blue reflection nebulae. Nine of the more spectacular examples of these dusty, blue stellar neighborhoods have been assembled here by astrophotographer Rob Gendler.

The Iris Nebula in a Field of Dust
12.09.2019

These cosmic dust clouds drift some 1,300 light-years away along the fertile starfields of the constellation Cepheus. The beautiful Iris Nebula, also known as NGC 7023, blossoms at the upper left. Not the only nebula in the sky to evoke the imagery of flowers, its pretty, symmetric form spans about 6 light-years.

Haunting the Cepheus Flare

Spooky shapes seem to haunt this dusty expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds visible in dimly reflected starlight. Far from your...

A Dusty Iris Nebula

Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers.
