GALAXY a wonderful and fitting name for its wonderful colors and a wide place. A one Galaxy has billions or trillions of stars. It also have millions of planets.
Someone once called galaxies 'star islands' in space. A galaxy is made up of huge group of STARS. Our SUN is just one star of about 100,000 million stars that belong to the Milky Way galaxy. A beam of light would take about 100,000 years to shine from one side of the Milky Way to the other. Yet the Milky Way is only a middle-sized galaxy.
Our galaxy belongs to what we call the Local Group - a collection of 30 galaxies. Few galaxies so far discovered at their correct distances apart, although their sizes are not to scale.
