Leo II (or Leo B) is a dwarf spheroidal galaxy about 690,000 light-years away in the constellation Leo.It is one of 24 known satellite galaxies of the Milky Way. [4] Leo II is thought to have a core radius of 178 ± 13 pc and a tidal radius of 632 ± 32 pc. [5]
The Leo II Groups, or Leo II Cloud, are a series of at least 110 galactic clusters and individual galaxies stretching approximately 30 Mly (9.2 Mpc) ecliptic west of the edge of the Virgo cluster. [ 1 ] [ 2 ] It is located approximately 65 Mly (20 Mpc) to 95 Mly (29 Mpc) from the Solar System , at a right ascension of 10 h 00 m to 11 h 40 m .
NGC 3608 is an elliptical galaxy located in the constellation Leo. It was discovered by William Herschel on March 14, 1784. [4] NGC 3608 is part of the Leo II Group of galaxies, including NGC 3605 and NGC 3607. It is approximately 13.0 billion years old.
The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022 [1]) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. [ 4 ]
James Webb Space Telescope unveils star-forming Leo P galaxy. The team studied Leo P using NASA’s James Webb Space Telescope, which imaged the dwarf galaxy with the instrument's Near-Infrared ...
It is a member of the NGC 3640 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [4] It lies 2 degrees south of Sigma Leonis and is a member of the Herschel 400 Catalogue. It is condensed and can be spotted with a small telescope from ...
It occupies the center of the Leo II Group of galaxies, forming one of its two brightest members – the other being NGC 3608. [3] It is a member of the NGC 3607 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [10]
"The location of this FRB so far outside its host galaxy raises questions as to how such energetic events can occur in regions where no new stars are forming.” Further study of fast radio bursts ...
