Samsung Galaxy

Samsung Galaxy (stylized as Samsung GALAXY or SAMSUNG Galaxy) is a series of mobile computing devices designed, manufactured and marketed by Samsung Electronics. The product line includes the Galaxy S series of high-end smartphones, the Galaxy Tab series of tablets, the Galaxy Note series of tablets and phablets with the added functionality of a stylus and the first version of the Galaxy Gear smartwatch, with later versions dropping the Galaxy branding.

Samsung Galaxy devices have traditionally used the Android operating system produced by the Open Handset Alliance led by Google, usually with a custom user interface called TouchWiz. This tradition was broken at CES 2016 with the announcement of the first Galaxy-branded Windows 10 device, the Samsung Galaxy TabPro S.

Galaxy

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few thousand (10³) stars to giants with one hundred trillion (10¹⁴) stars, each orbiting their galaxy's own center of mass. Galaxies, are categorized according to their visual morphology, including elliptical,spiral, and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of July 2015, EGSY8p7 is the oldest and most distant observed galaxy with a light travel distance of 13.2 billion light-years from Earth, and observed as it existed 570 million years after the Big Bang. Previously, as of May 2015, EGS-zs8-1 was the most distant known galaxy, estimated to have a light travel distance of 13.1 billion light-years away and to have 15% of the mass of the Milky Way.
