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.
Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within the Milky Way galaxy at a distance of about 125 parsecs (407 lightyears). [2]
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 ...
The Rosette Nebula is an example of an unusual shape that an elephant trunk can assume. It has a double helix structure instead of the normal straight column. [ 10 ] The double helix is caused by the presence of magnetic fields and electric currents lined up along the trunk axis of the trunks.
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.
In today's puzzle, there are six theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: FO. FE ...

NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. [2] A recent survey indicates the cluster contains more than 130 stars less than 1 million years old. [citation needed] NGC 7129 is located just half a degree from nearby ...
