Interstellar space is the physical space outside of the bubbles of plasma known as astrospheres, formed by stellar winds originating from individual stars, or formed by solar wind emanating from the Sun. [131] It is the space between the stars or stellar systems within a nebula or galaxy. [132]
Of several items, then called radio stars, Cygnus A was identified with a distant galaxy, being the first of many radio stars to become a radio galaxy. [25] [26] First quasar: 3C273: Virgo: 1962 3C273 was the first quasar with its redshift determined, and by some considered the first quasar. [citation needed] 3C48: Triangulum: 1960

[110] [111] [112] Most stars are within galaxies, but between 10 and 50% of the starlight in large galaxy clusters may come from stars outside of any galaxy. [113] [114] [115] A multi-star system consists of two or more gravitationally bound stars that orbit each other. The simplest and most common multi-star system is a binary star, but ...
A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
The Whirlpool Galaxy lies at a distance of 23 [2] to 31 million light-years from Earth. [18] Based on the 1991 measurement by the Third Reference Catalogue of Bright Galaxies using the D 25 isophote at the B-band, the Whirlpool Galaxy has a diameter of 23.58 kiloparsecs (76,900 light-years). [2] [5] Overall the galaxy is about 88% the size of ...
