Fact of the Day: Milky Way Galaxy

The galaxy we live in is called the Milky Way. The sun is just one of millions of stars in this huge disk-shaped area and our galaxy is just one of the millions scattered throughout the universe. Our galaxy is about 100,000 light-years across and about 1,000 light-years deep, meaning that a beam of light would take about 100,000 years to shine from one end to the other.
