The nebula RCW 34 is relatively dark. However, when observed using infrared wavelengths, two different areas are visible - one half of the nebula is bright, and the other is dark. The bright side is the hydrogen illuminated by a nearby blue supergiant star , and dark is the place where new stars surround the central star on the other side.
NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster. Two other objects are within this designation but not officially included, the Snowflake Cluster , [ 3 ] [ 4 ] and the Fox Fur Nebula . [ 5 ]
Enormous Lyα nebula (ELAN) The nebula is associated with the galaxy overdensity BOSS1441, [7] which is a protocluster at z=2.3. The nebula represents the circumgalactic medium. Its emission is powered by starburst and an obscured AGN. One of the most extended ELAN discovered as of 2019. [8] NGC 262 Halo Cloud 1,300,000 ly (400,000 pc) [9] H I ...

Halo: Nightfall—a series of weekly, episodic digital videos directed by Sergio Mimica-Gezzan and produced by Ridley Scott—launched soon after the collection was released. The series was designed to connect the stories of previous Halo games to the upcoming Halo 5. [3] The Halo 5 beta launched on December 29, 2014, and ran until January 18 ...
On 5 June 2020, NASA awarded Northrop Grumman Innovation Systems a $187 million contract to complete the preliminary design of HALO. [15] NASA signed a separate contract with Northrop for the fabrication of the HALO, and for integration with the Power and Propulsion Element (PPE), being built by Maxar , for US$935 million.
NGC 2014 is a red emission nebula surrounding an open cluster of stars in the Large Magellanic Cloud, at a distance of about 163,000 light-years. [2] The nebula was discovered on 3 August 1826 by Scottish astronomer James Dunlop. [3] Together with NGC 2020 it makes up what is called the Cosmic Reef. [2]
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
