Stars & Telescopes

Telescopes are tools we use to answer questions about the creation of galaxies, life cycles of distant stars or even the birth of the universe. Since telescopes collect starlight that has traveled millions of light years to reach us, they can give us an idea of how the universe looked long ago. Discover the kinds of information telescopes collect—images from the visible spectrum, infrared and x-ray data, and more.
