Horsehead & Flame Nebulae

The Horsehead Nebula, Barnard 33, is a dark cloud of dust and gas in front of the bright red emission nebula IC 434 in the constellation Orion. To the lower left of the Horsehead is the blue reflection nebula NGC 2023. To the left of both is the peach-colored Flame Nebula, which hides in its center a cluster of young stars that have been imaged in x-ray and infrared light. All are about 900 to 1500 light-years away. A closer view of the Horsehead Nebula, taken with a larger telescope, is shown below.
