Lab #1 ASTR 1103: Stars and Galaxies Spring 2024 Houston Community College Introduction: This laboratory assignment will apply conceptual information on what is present in the night sky and how we represent their positions. We will see how objects seemingly move over a period of a few months and demonstrate some behavior discussed in lecture. This assignment makes extensive use of the free astronomy program, Stellarium, in order to accurately simulate observations of the night sky. All questions can only be answered using this software. There are 8 “Tasks” for you to fill out, answer, and/or upload a screenshot. The points available for each task are stated above each one, with a total of 25 points across the entire assignment. Technology Tips: - Know how to take screenshots on your device - Many keyboards have a “Print Screen” key that you can press - On Windows, you can also press the Shift, Windows, and S keys simultaneously to select which area to screenshot - On Mac, you can also press Shift, Command, and 4 keys simultaneously to select which area to screenshot - On Android devices, you can press and hold the Power and Volume Down buttons to take a screenshot - On iPhone devices: - With only Face ID unlock: press and hold the Side Button and Volume Up - With Touch ID unlock: press and hold the Side Button and Home Button - Try to avoid taking a picture of your computer screen with your phone as your picture submission. These rarely turn out well! - Download and install Stellarium ( https://stellarium.org/ ) - Know what type of operating system your computer has to help pick out the correct version to install. - You can also use the Stellarium Web version if you’re on a public computer or mobile device. - Watch the Stellarium Tutorial video (48 minutes) on the Recordings page of our Canvas site for an in-depth demonstration on how to use Stellarium Submission Details: - Make sure you answer each question with the appropriate response type. Whether it's a text answer, filling out a table, or a screenshot picture.
