    en.wikipedia.org/wiki/Cosmic_distance_ladder

    The observational result of Hubble's law, the proportional relationship between distance and the speed with which a galaxy is moving away from us, usually referred to as redshift, is a product of the cosmic distance ladder. Edwin Hubble observed that fainter galaxies are more redshifted. Finding the value of the Hubble constant was the result ...

  4. Galaxy morphological classification - Wikipedia

    en.wikipedia.org/wiki/Galaxy_morphological...

    Spiral galaxy UGC 12591 is classified as an S0/Sa galaxy. [1]The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. [2] [3] It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.

  5. Hubble sequence - Wikipedia

    en.wikipedia.org/wiki/Hubble_sequence

    The same galaxy would look very different, if viewed edge-on, as opposed to a face-on or 'broadside' viewpoint. As such, the early-type sequence is poorly represented: The ES galaxies are missing from the Hubble sequence, and the E5–E7 galaxies are actually S0 galaxies. Furthermore, the barred ES and barred S0 galaxies are also absent.

    It was here, 100 years ago, that Edwin Hubble noted a light in the distance that would lead to one of science's greatest discoveries. By night, astronomers kept watch at the best telescopes on Earth.

    2005 – Spitzer Space Telescope data confirm what had been considered likely since the early 1990s from radio telescope data, i.e., that the Milky Way Galaxy is a barred spiral galaxy. [ 14 ] [ 15 ] 2012 – Astronomers report the discovery of the most distant dwarf galaxy yet found, approximately 10 billion light-years away.

    Later in the 1920s, Edwin Hubble showed that Andromeda was far outside the Milky Way by measuring Cepheid variable stars, proving that Curtis was correct. [6] It is now known that the Milky Way is only one of as many as an estimated 200 billion (2 × 10 11) [7] to 2 trillion (2 × 10 12) or more galaxies in the observable Universe.

    The Hubble Space Telescope is known for its dazzling images of cosmic phenomena, but it didn't exactly start that way. Its first ever image, captured 25 years ago today, is decidedly less exciting ...
