The Eskimo Nebula, formally NGC 2392, is a planetary nebula formed from a dying white dwarf star. Its distinctive double-shell structure, created by material ejected over thousands of years, makes it a notable example of stellar evolution. Discovered by William Herschel in 1787, this Hubble Space Te...

Gemini South is an 8.1-meter optical and infrared telescope on Cerro Pachón in the Chilean Andes, at an elevation of about 2,722 meters. It achieved first light in 2000 and forms one half of the international Gemini Observatory, paired with Gemini North on Mauna Kea in Hawaii. Its southern location...

Abell 21, also known as the Medusa Nebula, is an ancient planetary nebula in the constellation Gemini. It was catalogued by astronomer George Abell in his 1966 survey of planetary nebulae. Located approximately 1,500 light-years from Earth, this stellar remnant exhibits a braided, filamentary struct...

Completed in 1999 on Mauna Kea in Hawaii, the Gemini North Observatory houses an 8.1-meter optical and infrared telescope. It serves as the Northern Hemisphere component of the international Gemini Observatory, which operates in partnership with multiple countries to provide full-sky astronomical co...

NGC 2371-2372 is a bipolar planetary nebula located in the constellation Gemini, recognized by its distinct, double-lobed structure. Because of its unique appearance, its two lobes were historically cataloged as separate objects, NGC 2371 and NGC 2372. The nebula was discovered by astronomer William...
