NASA's Astronomy Picture of the Day for September 7, 2026, highlights the Pelican Nebula, showcasing its active star formation and evolving gas clouds.
Key facts
- •The Pelican Nebula is officially designated as IC 5070.
- •The featured image was captured in Utah, USA, using 25 hours of exposure.
- •A molecular cloud filled with dark dust separates the Pelican Nebula from the larger North America Nebula.
- •An ionization front marks the boundary where young stars are heating cold gas.
- •The nebula is bounded by the dark nebula LDN 935.
The Pelican Nebula, officially designated as IC 5070, is currently undergoing a slow transformation driven by active star formation and evolving gas clouds. A new image captured from Utah, USA, utilizes 25 hours of exposure to reveal the nebula's filamentary dust structures and its separation from the North America Nebula by a molecular cloud.
Nebula Composition and Evolution
The nebula is characterized by an ionization front, visible in bright orange on the upper right of the image, where light from young, energetic stars converts cold gas into hot gas. Dense tentacles of cold gas persist within the structure, which is bounded by the dark nebula LDN 935. Astronomers note that the nebula is a significant site for studying the interplay between star formation and gas evolution.
Future Appearance
The appearance of the Pelican Nebula is expected to change significantly over millions of years. As the placement and balance of its stars and gas continue to shift, the nebula will likely lose the features that currently give it its name.
