The dusty dark nebula to the right of NGC 1788 is LDN 1615, along with LDN 1616, which is a part of
NGC 1788, together they form a cometary cloud. The large dusty globu le to the south is a remnant
molecular cloud called OS 2. It is one of 85 remnant molecular clouds catalogued by the Japanese
astronomers Katsuo Ogura and Koji Sugitani in 1998. [Text and object recognition from a courtesy of Sakib Rasool]
About:
The delicate nebula NGC 1788 (called "The Cosmic Bat" or "The Foxface Nebula") is located
in a dark and often neglected corner of the Orion
constellation. 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. [Text from ESO]
