Explanation: The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But this wide and deep image combining data from two telescopes also reveals its extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the right, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552.

Webb rileva idrocarburi policiclici aromatici nelle regioni nucleari delle galassie di Seyfert

Questa immagine, ripresa con il Mid-InfraRed Instrument (MIRI) di Webb, mostra la galassia a spirale barrata NGC 7469. Gli astronomi hanno analizzato i dati disponibili al pubblico dello strumento Mid-Infrared (MIRI) del telescopio spaziale James Webb della NASA/ESA/CSA per tre galassie di Seyfert – NGC 6552, NGC 7469 e NGC 7319 – e hanno analizzato le proprietà dell’emissione di idrocarburi…

Explanation: The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But the composite image combines many short and long exposures to also reveal an extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star.

Кошачий глаз: широко и глубоко

http://astro-analytics.net

Туманность Кошачий глаз (NGC 6543) - одна из самых известных планетарных туманностей на небе. На этом широкоугольном снимке можно разглядеть более знакомые очертания центральной части туманности. Однако изображение составлено из множества снимков с большой и маленькой выдержкой, что позволило проявить очень слабое внешнее гало туманности. На расстоянии до туманности примерно в 3 000 световых лет гало протянулось более чем на 5 световых лет в поперечнике. Долгое время считалось, что планетарные туманности являются финальной стадией жизни звезды типа Солнца. Недавно исследователи начали открывать у некоторых подобных туманностей наличие протяжённого внешнего гало, что говорит о сбросе внешних частей оболочки звезды во время более ранних эволюционных стадий. Возрасты планетарных туманностей оцениваются примерно в 10 000 лет, а время жизни внешнего гало может составлять от 50 000 до 90 000 лет. В левой части изображения видна спиральная галактика NGC 6552, расположенная в каких-то 50 миллионах световых лет от красочной туманности.
