Witch head nebula
Do you believe in witches? Because I took a picture of the head of one such space witch.
NGC 1909, or otherwise known as IC 2118 (also known as the Witch's Head Nebula due to its shape), is an extremely faint reflection nebula thought to be an ancient supernova remnant or gas cloud illuminated by the nearby supergiant Rigel in Orion. It is located in the constellation Eridanus, about 900 light years from Earth. The blue color of the Witch's Head is due to the nature of dust particles, which reflect blue light better than red light. Radio observations show significant carbon monoxide emission throughout IC 2118, an indicator of the presence of molecular clouds and star formation in the nebula. In fact, deep in the nebula, candidates for pre-main-sequence stars and some classical T-Tauri stars have been found.
The molecular clouds in IC 2118 likely lie next to the outer boundaries of the giant Orion-Eridanus bubble, a huge superball of molecular hydrogen that was blown by the high-mass stars of the Orion OB1 association. As the superball expands into the interstellar medium, conditions favorable for star formation are created. IC 2118 is located in one such region. The wind-drifted appearance and cometary shape of the bright reflection nebula strongly suggest a strong association with the high-mass glowing stars of Orion OB1.
