How do we have images of the Milky Way when we are part of it?
The Milky Way is our home galaxy, a vast collection of stars, gas, and dust. It's about 100,000 light-years across, and it contains an estimated 100-400 billion stars.
We live in one of the Milky Way's spiral arms, about 27,000 light-years from the center. This means that we can't see the Milky Way from the outside, like we can see other galaxies.
However, we can still get images of the Milky Way. These images are typically taken from space telescopes, which are positioned far outside of the Milky Way. The telescopes can then take pictures of the galaxy in visible light, infrared light, and other wavelengths.
By combining these images, scientists can create a composite image of the Milky Way. These images show us the overall structure of the galaxy, as well as the distribution of stars, gas, and dust.
