Special telescopes, such as the Chandra X-ray Telescope, help astronomers see different kinds of electromagnetic radiation besides visible light. Why is this helpful?

• X-Rays give off a spectrum of light that tell astronomers what elements make up individual stars. ***
• X-Rays can travel faster to Earth so astronomers can see events taking place sooner with visible light.
• X-Rays can travel through dust to allow an astronomer to see more detail when looking at things like nebula.
