  1. galaxies

    A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias (γαλαξίας), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many are thought to have supermassive black holes at their centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of March 2016, GN-z11 is the oldest and most distant galaxy observed. It has a comoving distance of 32 billion light-years from Earth, and is seen as it existed just 400 million years after the Big Bang. In 2016, using 20 years of images from the Hubble space telescope, it was estimated that there were in total two trillion (2×1012) or more galaxies in the observable universe, and as many as an estimated 1×1024 stars (more stars than all the grains of sand on all beaches of the planet Earth).In 2021, data from NASA's New Horizons space probe was used to revise the earlier estimate to roughly 200 billion galaxies (2×1011),Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances on the order of millions of parsecs (or megaparsecs). For comparison, the Milky Way has a diameter of at least 26,800 parsecs (87,400 ly) and is separated from the Andromeda Galaxy (with diameter of about 152,000 ly), its nearest large neighbor, by 780,000 parsecs (2.5 million ly.) The space between galaxies is filled with a tenuous gas (the intergalactic medium) with an average density of less than one atom per cubic meter. Most galaxies are gravitationally organized into groups, clusters and superclusters. The Milky Way is part of the Local Group, which it dominates along with Andromeda Galaxy. The group is part of the Virgo Supercluster. At the largest scale, these associations are generally arranged into sheets and filaments surrounded by immense voids. Both the Local Group and the Virgo Supercluster are contained in a much larger cosmic structure named Laniakea.

Examples of Galaxies in a Sentence

  1. Marcel Neeleman:

    Most galaxies that we find early in the universe look like train wrecks because they underwent consistent and often' violent' merging, these hot mergers make Milky Way difficult to form well-ordered, cold rotating disks like we observe in our present universe.

  2. Ganga Sagar Pant:

    If you always look down and dark, you have possibility of going to depression; you can change yourself towards light and colorful lives by looking up. Look at the sky, stars, galaxies, the infinity of the Universe..., you will start shining and twinkling as you are truly one among those!

  3. Chris Carilli:

    We are seeing P352-15 as it was when the Universe was less than a billion years old, or only about 7 percent of its current age, this is near the end of a period when the first stars and galaxies were re-ionizing the neutral hydrogen atoms that pervaded intergalactic space. 'SUPERSTAR' ETA CARINAE ACTS LIKE A GINORMOUS COSMIC-RAY GUN, BUT WHY? Carilli added: Further observations may allow us to use this quasar as a background ‘lamp’ to measure the amount of neutral hydrogen remaining at that time.

  4. Dr Wolf:

    These large and rapidly-growing black holes are exceedingly rare, and we have been searching for them with SkyMapper for several months now. The European Space Agency’s Gaia satellite, which measures tiny motions of celestial objects, helped us find this supermassive black hole, as supermassive black holes shine, they can be used as beacons to see and study the formation of elements in the early galaxies of the universe.

  5. Marcin Glowacki:

    When galaxies collide, the gas they contain becomes extremely dense and can trigger concentrated beams of light to shoot out.
