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 ...

2022年11月12日 · NGC 1491, usually known as Sh2-206 or the Fossil Footprint Nebula, is an emission nebula located at about 10,700 light years in the constellation Perseus. The nebula is ionized by BD +50 886, an 11.2 magnitude star located just left of the center of this image and about in the center of the carved “cave” in the gas cloud around it.

NGC 1491 (also designated Sharpless SH2-206) 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 away in the Perseus arm of our Milky Way galaxy.

In the sky area of the constellation Perseus and about 10,700 light years distant from us, there is a bright emission nebula, the Fossil Footprint Nebula, cataloged as NGC 1491, although it is also included in the Sharpless catalog as Sh2 -206 and in the Lynds as LBN 704.

Wiki: 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.

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.

NGC 1491 is also known as LBN 704 and Cederblad 25. It is loosely associated with LBN 705, LBN,706, and Sh2-206. The latter identification, Sh2-206 covers the full field of this image (and more). NGC 1491 is an emission nebula structure with most of the Ionization energy coming from the star BD+50 886 (TYC3339-339-1).
