Assignments:

1) Reading/assignment for Friday: The table below shows which of these HST new stories you should read before class. Take notes as you read, and come to class prepared to share information about your object. You will find information under the "Introduction" tab, the "release text" tab, and with individual images. Click on the "Release Images" tab to find all the images associated with this story. Click on an individual image to get more information (sometimes) about that image.   Make a list of the key features in the images and the main points in the text. Focus on what the images are telling us about star formation.

It might be handy if one person in the group could bring a laptop to class on Friday, in case you want to look up more info about your image.

2)Bonus Assignment 3: Review of Observatory; Due Friday in class: Visit one space based and one ground based observatories  listed on the links page. Write a 1 to 2 page review about the observatory. They all have very different web pages. Some are more geared towards the information a visiting scientist might want, others have good sections of general interest, some even have virtual observatory tours. On all of the sites you'll have to poke around quite a bit to find interesting information. Things to look for include: What  telescopes do they have? What sort of work do they do? What science projects are they involved with? Where is it? Who runs it? Can you visit? Are images available? Do they have a virtual tour? What is the history of the observatory? Are there cool pictures of the telescopes? What do you find interesting about this observatory? For the space based observatory, look for: What wavelength are they studying? When was the telescope launched? What is its orbit? What are the mission goals? Are there cool images? What kind of objects are they studying? etc.

3) Looking ahead: Exam 2 is next week Wednesday!
