The delicate nebula NGC 1788, located in a dark and often neglected corner of the Orion constellation, is revealed in this finely nuanced image. Although this ghostly cloud is rather isolated from Orion’s bright stars, their powerful winds and light have a strong impact on the nebula, forging its shape and making it a home to a multitude of infant suns.

This image has been obtained using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. It combines images taken through blue, green and red filters, as well as a special filter designed to let through the light of glowing hydrogen. The field is about 30 arcminutes across; North is up, and East to the left.

This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. NGC 1788 is an unusual reflection nebula (bluish white at the center of the image) surrounded by a glowing red ring of hydrogen gas. The stars inside the nebula are only about a million years old, which is very young compared to most stars. The ring of glowing hydrogen gas is energized by nearby hot, massive stars not visible in the image. The image was generated with observations in the B (blue), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is up, East is to the left.

This image from the Digitized Sky Survey 2 covers a field of view of 3 x 2.9 degrees, and shows that the Bat Nebula is part of much larger nebulosity.

This skyscape finds an esthetic balance of interstellar dust and gas residing in the suburbs of the nebula rich constellation of Orion. Reflecting the light of bright star Rigel, Beta Orionis, the jutting, bluish chin of the Witch Head Nebula is at the upper left. Whiskers tracing the red glow of hydrogen gas ionized by ultraviolet starlight seem to connect that infamous visage with smaller nebulae, like dusty reflection nebula NGC 1788 at the right. Strong winds from Orion's bright stars have also shaped NGC 1788, and likely triggered the formation of the young stars within. Appropriate for its location, NGC 1788 looks to some like a cosmic bat. The scene spans about 3 degrees on the sky or 6 full Moons.
