Wisps Surrounding the Horsehead Nebula
Image Credit & Copyright: Mario Zauner [3]
Explanation: The famous Horsehead Nebula in Orion is not alone. A deep
exposure shows that the dark familiar shaped [4] indentation, visible just
below center, is part of a vast complex [5] of absorbing dust [6] and
glowing gas [7] . To bring out details of the Horse [8] head's pasture, an
amateur astronomer used a backyard telescope in Austria [9] to accumulate and
artistically combine 7.5 hours of images in the light of Hydrogen [10] (red),
Oxygen [11] (green), and Sulfur [12] (blue). The resulting spectacular
picture [13] details an intricate tapestry of gaseous wisps [14] and
dust-laden filaments [15] that were created and sculpted [16] over eons by
stellar winds [17] and ancient supernovas [18] . The Flame Nebula [19] is
visible just to the left of the Horsehead, while the bright star on the upper
left is Alnilam [20] , the central star in Orion's Belt [21] . The Horsehead
Nebula [22] lies 1,500 light years [23] distant towards the constellation
[24] of Orion [25] .
