The Phoenix Cluster (SPT-CL J2344-4243) is a massive, Abell class type I galaxy cluster located at its namesake, southern constellation of Phoenix. It was initially detected in 2010 during a 2,500 square degree survey of the southern sky using the Sunyaev–Zeldovich effect by the South Pole Telescope collaboration. [ 5 ]

Epsilon Phoenicis is a star in the southern constellation of Phoenix. It is visible to the naked eye with an apparent visual magnitude of 3.87. [2] The distance to this star is approximately 144 light years based on parallax measurements, but it is drifting closer with a heliocentric radial velocity of −9.2 km/s. [5]
The Fornax Cluster is a cluster of galaxies lying at a distance of 19 megaparsecs (62 million light-years). [3] It has an estimated mass of (7 ± 2) × 10 13 solar masses, [4] making it the second richest galaxy cluster within 100 million light-years, after the considerably larger Virgo Cluster. It may be associated with the nearby Eridanus Group.
The term "The Local Group" was introduced by Edwin Hubble in Chapter VI of his 1936 book The Realm of the Nebulae. [11] There, he described it as "a typical small group of nebulae which is isolated in the general field" and delineated, by decreasing luminosity, its members to be M31, Milky Way, M33, Large Magellanic Cloud, Small Magellanic Cloud, M32, NGC 205, NGC 6822, NGC 185, IC 1613 and ...
NGC 25 is a barred lenticular galaxy situated in the Phoenix constellation. It was discovered on 28 October 1834 by John Herschel. It is the brightest cluster galaxy for Abell cluster 2731. [2] A supernova was discovered in NGC 25 on 15 November 2020. [3] [4] NGC 25 with DECam
Alpha Phoenicis is a spectroscopic binary star system with components that orbit each other every 3,848.8 days (10.5 years). [6] The combined stellar classification of the system is K0.5 IIIb, [3] which matches the spectrum of a normal luminosity giant star.
