    en.wikipedia.org/wiki/Large_Magellanic_Cloud

    The Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. At a distance of around 50 kiloparsecs (163,000 light-years), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.

    The Orion Arm is one of the spiral arms of our Milky Way galaxy. Astrometrics [ edit ] The easiest way to determine stellar distance to the Sun for objects at these distances is parallax , which measures how much stars appear to move against background objects over the course of Earth's orbit around the Sun.

    The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.

  9. TON 618 - Wikipedia

    en.wikipedia.org/wiki/TON_618

    As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc. Given its observed redshift of 2.219, the light travel time of TON 618 is estimated to be approximately 10.8 billion years.
