Which section of the spectrum is the ONLY one we can see?

• X-rays

• Visible Light

• Gamma Rays

• all

How can you rearrange the words to match the diagram correctly in terms of sizes in space?

• Solar systems in the largest circle, then galaxies, followed by the universe in the smallest circle.

• Universe in the largest circle, then galaxies, followed by the solar systems in the smallest circle.

• Galaxies in the largest circle, then universe, followed by the solar systems in the smallest circle.

• The diagram is already correct.

Astronomers make observations in visible light, but also in other parts of the electromagnetic spectrum, such as radio waves and gamma rays. Scientists make observations in different wavelengths because...

• visible light only provides information about the closest objects in our galaxy.

• the information provided by visible light is not a reliable source of data.

• the equipment required for observations in other wavelengths is expensive.

• observations in different wavelengths provide different information about stars.
