In perhaps an unintended degree of verisimilitude to the actual shuttle launch experience, a lot of the time on the Shuttle Launch Experience ride is spent waiting. As you wait on the gantry, monitors show a video where former astronauts describe what it was like for them to fly on the shuttle.
The galaxy we live in, called the Milky Way Galaxy, is a barred spiral galaxy composed of at least 100 billion stars. It is approximately 100,000 light years across and about 1000 light years thick. It has a central bulge that is about 10,000 light years in diameter.
Credit: NASA. We live in a galaxy that is called the Milky Way. It's called a barred spiral galaxy, which means that it has a spiral shape with a bar of stars across its middle. The galaxy is rather hugeâat least 100,000 light-years in diameter, making it the second-biggest in our Local Group of galaxies.redit: NASA. We live in a galaxy that is called the Milky Way.
