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 than with visible light.***
• X-rays can travel through dust to allow an astronomer to see more detail when looking at strange things like nebula.
