Sharpless 140 is an H II region and emission nebula in the Cepheus constellation, [2] 3,000 light years from the Solar System. [1] It is part of the Cepheus bubble. [3] The surface of the nebula's clouds primarily consists of polycyclic aromatic hydrocarbons. [4]

This view into deep space reveals a pocket of hydrogen emission (Ha) peeking out behind a large dust cloud. Fortunately, looking with high magnification reveals some additional detail. You can see...

2018年11月19日 · Sharpless2-140 (Sh2-140) refers to the hydrogen alpha emission and Lynd's 1204/2304 (LDN 1204/2304) is the dark nebula throughout frame. It is immediately apparent that the dark nebula hangs in front due to the lack of stars in the area.

Sh2-140 is a hydrogen emission nebula located approximately 3,000 light-years away on the edge of a ring of molecular gas and dust known as the Cepheus Ring. From what I can tell in the literature, Sh2-140, refers to the more dense star forming the bottom edge of the nebular complex while LBN 505 is the nebula as a whole.

2014年8月1日 · Sh2-140 is an HII emission nebula on the southwest edge of the Lynds 1204 darn nebula. It is also on the edge the Cephus Ring, a ring of molecular gas and…

2020年6月30日 · Sh2-140 is an HII emission nebula on the southwest edge of the Lynds 1204 darn nebula. It is also on the edge the Cephus Ring, a ring of molecular gas and dust. Invisible in this image, there are about fifty young stars deeply embedded in the dark gas in the lower-left corner of the image.

2020年11月15日 · Here’s my latest image of Sh2-140, taken over 4 nights in August and September. Thanks for looking! Description: Sharpless 140 is a H-II region that lies 3000 light years away in the constellation Cepheus. Obscuring a portion of the emission nebula is Lynds 2304, a dark nebula to the lower right of the main complex.

2024年11月22日 · SH2-140 Wiki: Sharpless 140 is an H II region and emission nebula in the Cepheus constellation, 3,000 light years from the Solar System. It is part of the Cepheus bubble.

Sh2-140 is an HII emission nebula on the southwest edge of the Lynds 1204 darn nebula. It is also on the edge the Cephus Ring, a ring of molecular gas and dust. Sh 2-140 is part of the Cepheus Bubble, the expanding shell of gas and dust surrounding the Cep OB2 association.

Sh2-140 is a visible emission nebula in the constellation of Cepheus ; it is part of the great star-forming region of the Cepheus molecular nebula complex . Taken with a Planewave 24" f6.5 on a Planewave HD Mount and a SBIG 16803 camera.
