Partner students and pose the question “How do we know anything about stars that are hundreds of light-years away?” Give students the opportunity to talk to their partner about the answer to the question in a think-pair-share. Once students have had time to think and share, call on students to share what they discussed together in their groups confrm correct comments and correct any misunderstandings.
