Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet -like objects that same year. [4] M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071.

2024年8月25日 · M78 was discovered in 1780 by Charles Messier’s colleague Pierre Méchain. It is best seen in January. M78 can be found in binoculars and small telescopes, but telescopes 8 inches or larger will reveal more detail in the nebula. M78 has the distinction of appearing very comet like, with one side of the nebula flaring away like a comet’s tail.

Messier 78 (M78, NGC 2068) is a beautiful blue reflection nebula in the constellation Orion. It is the brightest diffuse reflection nebula in a group of nebulae that includes NGC 2064, NGC 2067, and NGC 2071.

2024年5月23日 · This breathtaking image features Messier 78 (the central and brightest region), a vibrant nursery of star formation enveloped in a shroud of interstellar dust. This image is unprecedented – it is the first shot of this young star-forming region at this width and depth.

2015年8月1日 · Messier 78 (M78) is a reflection nebula located in the northern constellation Orion, the Hunter. M78 is the brightest diffuse reflection nebula in the sky. It has an apparent magnitude of 8.3 and lies at an approximate distance of 1,600 light years from Earth. It has the designation NGC 2068 in the New General Catalogue.

2021年1月21日 · One of the brightest, M78, is centered in this colorful, wide field view, covering an area north of Orion’s belt. At a distance of about 1,500 light-years, the bluish reflection nebula is around 5 light-years across.

M78 is a bright reflection nebula located close to the celestial equator, and about four degrees east of Mintaka (Delta Orionis), the westernmost star in Orion’s belt. Like all reflection nebulae, M78 is seen because it scatters light from another source, usually nearby stars.

M78并不难找，可以从猎户腰带上最东侧的恒星，猎户座Zeta，即參宿一（Alnitak）开始寻找；M78位于这颗恒星以北约2度，以东1 1/2度的地方；Zeta星向北伸出的3颗5-6等的一串恒星，也许可以帮你定位。

Messier 78 (M78), a fascinating reflection nebula, is one of the brightest nebulae in the night sky. Located in the constellation Orion, M78 offers amateur astronomers a striking view of cosmic dust illuminated by the glow of nearby stars.
