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 ...
An analysis of Gaia data suggests that the central star is a binary system. [7] Visible-light observations capture the glow of gases including hydrogen and nitrogen. [ 8 ] The total mass of the nebula is estimated to be around 0.22 M ☉ , most of which is ionized gas (0.21 M ☉ ) and a small fraction ( 8.9 × 10 −4 M ☉ ) is carbon-rich dust.
NGC 2736 (also known as the Pencil Nebula) is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula's linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from the Solar System. It is thought to be formed from part of the shock wave of the ...

The overall nebula with smaller hole shown in context. NGC 1999, also known as The Cosmic Keyhole, [1] [2] is a dust-filled bright nebula with a vast hole of empty space represented by a black patch of sky, as can be seen in the photograph. It is a reflection nebula, and shines from the light of the variable star V380 Orionis.
