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.

of all possible answers, your choice is the worst. x-rays are just another kind of light. Nothing goes faster than light!

So C

The correct answer is:

• X-rays can travel faster to Earth so astronomers can see events taking place sooner than with visible light.

This is helpful because different kinds of electromagnetic radiation provide astronomers with different information about the objects they are observing. X-rays, for example, have higher energy and shorter wavelengths than visible light, which means they can provide valuable information about high-energy events in the Universe. The Chandra X-ray Telescope, specifically designed to detect X-rays, allows astronomers to observe and study objects such as black holes, active galactic nuclei, supernova remnants, and other celestial phenomena that emit X-rays.

X-rays can travel at the speed of light, which is faster than visible light, allowing astronomers to observe and gather data on events taking place in real-time. For example, when a massive star explodes in a supernova, the X-rays emitted from the event reach our telescopes on Earth before the visible light does. By studying these X-rays, astronomers can gain a better understanding of the physics behind such explosive events and their impact on the surrounding environment.

So, by using special telescopes like the Chandra X-ray Telescope, astronomers can complement their observations in visible light with data from different regions of the electromagnetic spectrum, which helps them gain a more complete picture of the Universe and its various phenomena.
