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 ...
NGC 6914 is a reflection nebula located approximately 6,000 light-years away in the constellation of Cygnus, and was discovered by Édouard Stephan on August 29, 1881. [3] Ultraviolet radiation from stars in the Cygnus OB2 association ionize the nebula's hydrogen.
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.

NGC 1360, also known as the Robin's Egg Nebula, [4] is a planetary nebula in the constellation of Fornax. It was identified as a planetary nebula due to its strong radiation in the OIII bands. Reddish matter, believed to have been ejected from the original star before its final collapse, is visible in images. [5]
Why? The sun's outermost layer, the elusive corona, was brighter, the moon appeared larger and the uncharacteristic darkness known as totality lasted just a bit longer.
