NGC 1376 is a spiral galaxy located around 180 million light-years away in the constellation Eridanus. [1] It was discovered in 1785 by William Herschel, and it is 79,000 light-years across. [1] NGC 1376 is not known to have an active galactic nuclei, but it does have lots of star-forming regions. [2] [3]

Characteristics

Concentrated along the spiral arms of NGC 1376, bright blue knots of gas highlight areas of active star formation. [4] These regions show an excess of light at ultraviolet (UV) wavelengths because they contain brilliant clusters of hot, newborn stars that are emitting UV light. [2] The less intense, red areas near the core and between the arms consist mainly of older stars. [4] [2] The reddish dust lanes delineate cooler, denser regions where interstellar clouds collapse to form new stars. [1] Behind the spiral arms is a sprinkling of reddish background galaxies. [2]

NGC 1376 belongs to a class of spirals that are seen nearly face on from our line of sight. [1] Its orientation aids astronomers in studying details and features of the galaxy from a relatively unobscured vantage point. [2]

NGC 1376 is home to a supernova (SN 1990go) [2] that rivaled the brightness of the entire nucleus (as seen from ground-based telescopes) for several weeks. This was observed in 1990. [2] [3]

Messier 63 or M63, also known as NGC 5055 or the seldom-used Sunflower Galaxy, is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars. M63 was first discovered by the French astronomer Pierre Méchain, then later verified by his colleague Charles Messier on 14 June 1779. The galaxy became listed as object 63 in the Messier Catalogue. In the mid-19th century, Anglo-Irish astronomer Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.

NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, similar to the distance of M101 in the constellation Ursa Major. Both were once considered to be part of the Local Group, but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.
