NGC 1491, also known as LBN 704, SH2-206 or the Fossil Footprint Nebula, is an emission type bright nebula located about 9,800 light years away from Earth in the constellation of Perseus. [1] The nebula gets its deep red coloration due to many massive stars (such as BD+50 866 ) embedded within NGC 1491 producing large amounts of ultraviolet ...

2024年3月1日 · The Fossil Footprint Nebula (Sh2-206, NGC 1491, LBN 704) is an irregular nebula containing both HII-emission and reflection areas. It is approximately 9,800 light-years (ly) away from Earth in the constellation of Perseus.

Other designation for this H-II region are: LBN 704, Sharpless 2-206, S 206, Sh2-206. Physical Properties. There are two measured distances on Simbad: 3.0 kpc and 3.3 kpc (9780 and 10'800 light years). The distance to the centre of the Milky Way is about 11.1 kpc (36'200 light years).

NGC 1491 (also designated SH2-206 and LBN 704) is a bright emission nebula and HII region, located on the edge of a vast cloud region of neutral gas, about 10 700 light-years. HII regions are well known for being places where new stars are born, and are created when ultraviolet radiation from hot stars ionizes the surrounding gas, causing it to ...

The central part of this interesting-looking nebula is NGC 1491 or LBN 704 to 706 or SH2-206, also called the Fossil Footprint Nebula. It is part of a larger gas cloud in the Perseus arm, at a distance of about 10700 light years. The central part is quite bright and is …
