Did you know that some objects in the universe shine brighter than a trillion Suns? These objects are called quasars. Quasars were discovered in the 1960s. Today, scientists are still working to learn more about them.
Write a report about quasars. To do so, you will need to conduct research. Here are some questions to guide your research:
What are quasars?
Why do quasars look like faint points of light when viewed from Earth?
Why is the light we see from quasars very old?
What can scientists conclude about a quasar's galaxy if a quasar is moving farther away from Earth?
Are you ready? Begin by visiting the Web sites in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.
With teacher supervision, you may use search engines to research other Web sites. You also can research quasars at the library. When you are ready, follow Steps 3 and 4 to write your report.
