NGC 2346 is a planetary nebula near the celestial equator in the constellation of Monoceros, [5] less than a degree to the ESE of Delta Monocerotis. [6] It is informally known as the Butterfly Nebula. [3] The nebula is bright and conspicuous with a visual magnitude of 9.6, [3] and has been extensively studied.

1999年10月7日 · NGC 2346, in contrast to the first two young objects, is a so-called "planetary nebula," which is ejected from Sun-like stars which are near the ends of their lives. NGC 2346 is remarkable because its central star is known to be actually a very close pair of stars, orbiting each other every 16 days.

2008年3月23日 · The Hubble Space Telescope captured this image of the "butterfly wing"- shaped nebula, NGC 2346. The nebula is about 2,000 light-years away from Earth in the direction of the constellation Monoceros. It represents the spectacular "last gasp" of a binary star system at the nebula's center.

NGC 2346 is a Planetary Nebula in the Monoceros constellation. NGC 2346 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

2016年3月2日 · NGC 2346, the Butterfly Nebula, achieved its remarkable dual-lobed or bi-polar shape in part because of interactions between the two stars at its center. The nebula is located about 2,000 light-years from Earth in Monoceros.

1999年10月7日 · NGC 2346 is a so-called "planetary nebula," which is ejected from Sun-like stars which are near the ends of their lives. NGC 2346 is remarkable because its central star is known to be actually a very close pair of stars, orbiting each other every 16 days.

NGC 2346 is a planetary nebula made of gas and dust that has evolved into a familiar shape. At the heart of the bipolar planetary nebula is a pair of close stars orbiting each other once every sixteen days.

1997年3月14日 · The Hubble Space Telescope's Wide Field and Planetary Camera 2 (WFPC2) is back at work, capturing this black-and-white image of the "butterfly wing"-shaped nebula, NGC 2346. The nebula is about 2,000 light-years away from Earth in …

2025年3月2日 · NGC 2346 is a planetary nebula located in the constellation Monoceros, approximately 2,000 light-years from Earth. It is classified as a bipolar planetary nebula, with a distinctive butterfly-like morphology.

NGC 2346 is a planetary nebula near the celestial equator in the constellation of Monoceros, less than a degree from Delta Monocerotis. It is informally known as the Butterfly Nebula. The core nebula is bright and conspicuous, with a visual magnitude of …
