Bluish Planetary Nebulae HFG1 and Abell 6 Immersed in a Glowing Field of Hydrogen Gas
Alqueva´s Dark Sky Reserve | By Year: 2025 | Deep Sky Wide Field
Captured in HaOIII and RGB light, the image features a deep wide field view immersed in the glow of ionized hydrogen gas, where small planetary nebulae Abell 6 and larger HFG1 (Heckathorn-Fesen-Gull 1 nebula type) seems to live, in the constellation of Cassiopeia. Being both remnants from the last phase of a medium star like our Sun. HFG1 features a bluish arc shaped shock wave, created by the binary star system V664 Cas, which comprises a white dwarf and a red giant star only a few million kilometres apart from each other. The small bright bluish ball visible near the center of the image, is known as Abell 6. Those kind of planetary nebulae, has a short life span of only about 10,000 years, becoming then invisible due to a lack of ultraviolet light emitted by the stars that create them. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: Captada em diferentes comprimentos de onda entre a luz Ha, OIII e RGB, a imagem apresenta uma visão ampla e profunda, imersa no brilho do gás hidrogénio ionizado, onde a pequena nebulosa planetárias Abell 6 e a mais extensa HFG1 (nebulosa planetária de tipo: Heckathorn-Fesen-Gull 1) parecem viver, na constelação de Cassiopeia. Sendo ambos remanescentes da última fase de uma estrela média como o nosso Sol. HFG1 apresenta uma onda de choque em forma de arco azulado, criada pelo sistema estelar binário V664 Cas, que compreende uma anã branca e uma estrela gigante vermelha, orbitando a apenas alguns milhões de quilómetros de distância uma da outra. A pequena bola azulada brilhante visível perto do centro da imagem, é conhecida como Abell 6. Este tipo de nebulosa planetária tem uma vida curta de apenas cerca de 10.000 anos, tornando-se então invisível devido à falta de luz ultravioleta emitida pelas estrelas que as criaram. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal.
