IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection [2] /emission [3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.
Cheomseongdae (Korean: 첨성대; Hanja: 瞻星臺; lit. star-gazing tower) is an astronomical observatory in Gyeongju, South Korea.Cheomseongdae is the oldest surviving astronomical observatory in Asia, [1] [2] [3] and possibly even the world.
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
The first star in the list, Godzilla [1] — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the 19th ...
This is a list of the brightest natural objects in the sky. This list orders objects by apparent magnitude from Earth , not anywhere else . This list is with reference to naked eye viewing; all objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly.
LBN 114.55+00.22 is an emission nebula in the constellation Cassiopeia. [1] Named after the astronomer who published a catalogue of nebulae in 1965, LBN stands for “Lynds Bright Nebula." The numbers 114.55+00.22 refer to nebula's coordinates in the Milky Way Galaxy. Dust blocks most of the visible light from this nebula. [1]
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
Lynds' Catalogue of Bright Nebulae (abbreviation: LBN) is an astronomical catalogue of bright nebulae. Objects listed in the catalogue are numbered with the prefix LBN (not to be confused with LDN, or Lynds' Catalogue of Dark Nebulae ).
