NASA Astronomy Picture of the Day 10 May 2023: Milky Way Galaxy visible in Egyptian skies
The Milky Way Galaxy is our home galaxy. Our solar system, with the Sun at the centre and 8 other planets, reside in an obscure part of the Galaxy. It is a barred spiral galaxy which spans about 100,000 light-years across and was formed approximately 14 billion years ago. The Milky Way Galaxy has over 100 billion stars and all of them orbit a supermassive black hole at the galaxy's center, which is estimated to be four million times as massive as our Sun, according to NASA.
