The recent observation of the Cassiopeia constellation has revealed three previously unidentified faint nebulas. The imaging process required 100 hours of exposure time and the application of a specialized oxygen filter to capture these structures.
The study highlights the presence of ionized oxygen in these new objects, labeled 1, 2, and 3. Researchers suggest that Object 3 might result from a bow shock created as the multi-star system Gamma Cassiopeia moves through interstellar medium, while Object 1 could potentially be a planetary nebula.
These findings complement the existing observations of IC 59 and IC 63, known as the Ghosts of Cassiopeia. The research team, including Louis Leroux-Géré, Thibault Rouillée, Vincent Martin, and Cédric de Decker from Starfront Observatories, continues to investigate the origins of these phenomena.
