NGC 7023 | ||
 | ||
| Description: | Though often refered to as NGC 7023, the blue reflection nebula pictured here is properly named LBN 487, while the loose star cluster at the bottom of the nebula is NGC 7023. The nebula's common name, The Iris Nebula, is much more evocative and descriptive. It was discovered by Freidrich Herschel in 1794. The young, bright central star is illuminating surrounding dust clouds. The reflected light is stongest in the blue part of the spectrum. | |
