Briefings
The APOD article from November 9, 2026, features the Witch Head Nebula (IC 2118), a 50-light-year-wide blue nebula in Orion's belt. Its shape resembles a witch's head due to the star Rigel's intense blue light and dust scattering. The nebula is about 50 light-years across and was formed by Rigel's erosion. The article explains that the blue color results from Rigel's starlight and atmospheric scattering, noting that Earth's atmosphere also scatters blue light. The image was credited to Piotr Czerski with editors Robert Nemiroff, Jerry Bonnell, Cecilia Chirenti, and Keighley Rockcliffe.
Key points
- The Witch Head Nebula (IC 2118) is approximately 50 light-years across and located in Orion's belt.
- The nebula's blue color is caused by Rigel's intense blue starlight and atmospheric scattering of blue light.
