Name:NQ,‘t\ ‘{\(\\\\(\Q\(\\a’ Navigating the Night Sky In this week’s lab, we are going to use the planetarium to learn about a few of the constellations that are currently observable this time of year, as well as discover how to point out the locations of objects in the sky, including Polaris, the north star. LAB EXERCISE PART I: AN INTRODUCTION TO THE NIGHT SKY For the first part of this lab, your lab instructor will show you which bright stars and/or constellations are viewable tonight around 10pm. 1. Name three constellations and two asterisms that your lab instructor pointed out, and in which general direction you would look to find it tonight around 10pm.

g Navigating the Night sy PART VI: FURTHER INVESTIGATIONS You've learned a lot about finding objects on the celestial sphere, but all of it has been based on your current location and the fact that you live on Earth. * Name one observation that would be different if you observed it at a different time of night, or a different night of the year? Explain how it would be different. I\l Cgpivex M diegefent Seasors oy WEAW X - * Name one observation (different from above) that would change if you lived somewhere else on Earth?

As we progress through the labs each week, we will end the lab with considering related projects that could be pursued. At the end of the semester, you will choose one of these research projects to complete, so keep that in mind as you work on each lab. Scanned with CamScanner
