http://SharenInvite.com/?refer=499925
The history of Valentine’s Day–and the story of its patron saint–is shrouded in mystery. We do know that February has long been celebrated as a month of romance, and that St. Valentine’s Day, as we know it today, contains vestiges of both Christian and ancient Roman tradition. But who was Saint Valentine, and how did he become associated with this ancient rite?
Every February 14, across the United States and in other places around the world, candy, flowers and gifts are exchanged between loved ones, all in the name of St. Valentine. But who is this mysterious saint, and where did these traditions come from? Find out about the history of this centuries-old holiday, from ancient Roman rituals to the customs of Victorian England.

Galaxy

NGC 4414, a typical spiral galaxy in the constellationComa Berenices, is about 55,000 light-years in diameter and approximately 60 million light-years away from Earth
galaxy is a gravitationally bound system of starsstellar remnants,interstellar gasdust, and dark matter.[1][2] The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to theMilky Way. Galaxies range in size from dwarfs with just a few thousand (103) stars to giants with one hundred trillion (1014) stars,[3] each orbiting their galaxy's own center of mass. Galaxies are categorized according to their visual morphology, including elliptical,[4] spiral, andirregular.[5] Many galaxies are thought to have black holes at theiractive centers. The Milky Way's central black hole, known asSagittarius A*, has a mass four million times greater than the Sun.[6]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.[7][8][9][10]
Approximately 170 billion (1.7 × 1011) to 200 billion (2.0 × 1011) galaxies exist in the observable universe.[11] Most of the galaxies are 1,000 to 100,000 parsecs in diameter and usually separated by distances on the order of millions of parsecs (or megaparsecs). The space between galaxies is filled with a tenuous gas with an average density less than one atom per cubic meter. The majority of galaxies are gravitationally organized into associations known as galaxy groupsclusters, and superclusters. At the largest scale, these associations are generally arranged into sheets and filaments that are surrounded by immense voids.
