Learning Goal: I’m working on a astronomy project and need an explanation and answer to help me learn.
Project Description
Use the Citizen ASAS-SN Zooniverse project to help identify variable star light curves.
Go to https://www.zooniverse.org/projects/tharinduj/citizen-asas-sn
ASAS-SN Stands for All-Sky Automated Survey for Supernovae. It is a network of 24 telescopes located at sites around the world that is capable of surviving the entire visible night sky each day. While the network is looking for new supernovae it also finds other variable stars (stars who’s brightness changes over time).
In this project you will help to classify different types of variable stars based on their light curves (plots of brightness as a function of time).
Start by clicking on Learn More and reading through the page. Also have a look at the ASAN-SN Variable Stars Atlas (Links to an external site.). Click on the the Get Started button and read through the tutorial.
Classify 5 stars.
What to Include in your Project Submission
Include an image which is a collage of the screen shots of your 5 light curves. Include a table that contains your classification and your reasoning for that classification.
The reflection Questions.
Reflection Questions (maximum 500 Words)
The ASAN-SN Variable Stars Atlas (Links to an external site.) puts variable star types into two different categories: Extrinsic and Intrinsic. What is the difference between these two types of variable stars?
Are pulsating variable, eclipsing binary and rotational variable stars Extrinsic or Intrinsic variable stars.
Were there any light curves that you were unsure of the classification for? If you had to do this project again is there any thing you would change?
Please cite all your sources! Note that if you cited a source for your project plan and you use it again for the project, you must also cite it again!

The Milky Way and the Andromeda galaxy are predicted to collide in about 4 billion years. Notice in the simulation that the two galaxies pass through each other, move a bit apart and then collide again in a series of “bounces” until they completely merge.

The Milky Way and the Andromeda galaxy are predicted to collide in about 4 billion years. Notice in the simulation that the two galaxies pass through each other, move a bit apart and then collide again in a series of “bounces” until they completely merge. The expectation is that this collision wouldn’t affect the solar system much, and that it is unlikely that any two stars would collide. Of course, by then the Sun will have expanded and it is unlikely that there would be anything alive on Earth to witness any of it!
