The Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), also known as the Sagittarius Dwarf Elliptical Galaxy (Sgr dE or Sag DEG), is an elliptical loop-shaped satellite galaxy of the Milky Way.

A dwarf spheroidal galaxy (dSph) is a term in astronomy applied to small, low-luminosity galaxies with very little dust and an older stellar population. They are found in the Local Group as companions to the Milky Way and as systems that are companions to …

The Carina Dwarf Spheroidal Galaxy is a dwarf galaxy in the Carina constellation. It was discovered in 1977 with the UK Schmidt Telescope by Cannon et al. [5] [6] The Carina Dwarf Spheroidal galaxy is a satellite galaxy of the Milky Way and is receding from it at 230 km/s. [1] The diameter of the galaxy is about 1600 light-years, which is 75 ...

Dwarf Spheroidal Galaxies are the faintest and lowest surface brightness galaxies known, revealing complex stellar populations and serving as laboratories for studying star formation and chemical enrichment processes at the faint end of the galaxy luminosity function.

2024年8月27日 · The Andromeda galaxy, also known as Messier 31, is the Milky Way’s closest grand spiral galaxy neighbor, and is host to at least 13 dwarf galaxies that orbit around it. The Pegasus Dwarf spheroidal galaxy is one of these mini-galaxies. Dwarf spheroidal galaxies are the dimmest and least massive galaxies known.

2024年8月27日 · The NASA/ESA Hubble Space Telescope has captured this spectacular image of the Pegasus dwarf spheroidal galaxy, a satellite of the Andromeda galaxy. The Pegasus dwarf spheroidal galaxy resides around 959,000 light-years away from the Andromeda Galaxy.

Burkert (1997) investigated four dwarf spheroidal galaxies orbiting around the Milky Way: Sextans, Carina, Ursa Minor and Draco, considering their tidal radii, and concluded that Sextans is dark matter dominated but not the other three.

1994年12月1日 · Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies.

2024年8月28日 · The Hubble Space Telescope has once again peered into the depths of our universe, revealing a hidden gem: the Pegasus Dwarf Spheroidal galaxy, also known as Andromeda VI. This faint, starry mini-galaxy orbits the Andromeda galaxy, one of the Milky Way’s closest galactic neighbors.

The Sagittarius Dwarf Elliptical Galaxy, also known as the Sagittarius Dwarf Spheroidal Galaxy, is an elliptical loop-shaped satellite galaxy of the Milky Way.
