Photo taken by the Hubble Space Telescope

This image of the Star-Forming Nebula N90 shows a rich star-forming region in the Small Magellanic Cloud, a satellite galaxy of our Milky Way.

Facts of interest about the image

This is a composite of Chandra, Hubble, and Spitzer data. The Chandra data are shown in purple; visible light data from the Hubble Space Telescope are shown in red, green, and blue; and infrared data from the Spitzer Space Telescope are shown in red.

Classroom activity

Included is an inquiry-based classroom activity that focuses on the image and text.

Description

This composite image from the Hubble Space Telescope, Chandra X-ray Observatory and Spitzer Space Telescope showcases a colorful view of the star-forming nebula, N90, located in the Small Magellanic Cloud. The image provides astronomers with a fuller census of the number and types of stars that are forming and have formed in this nebula. Includes a classroom activity.

How to use in the classroom

Teachers can use this lithograph as:

An example of why astronomers use different regions of the Electromagnetic Spectrum. Use the inquiry-based classroom activity, "In Search of … the Electromagnetic Spectrum," that is included with the PDF lithograph.

An engagement tool in an inquiry-based lesson. Have students study the images on the lithograph. Ask them to write down any questions they have about the images. When the students are finished, their questions can be used in a variety of ways:


  • Ask students to find the answers to their questions by reading the text on the lithograph and/or the related materials listed below.

  • Have students exchange papers so that each student has someone else's questions. Then have them find the answers to the other students' questions by reading the text on the lithograph and/or the related materials listed below.

  • Gather the questions into a list by asking students to volunteer to read their questions while you or another student records them. Ask students to raise their hands if they had the same or a similar question. Count the number of hands raised and record this number next to the question. Once all the student questions have been added to the list, have students search for the answers to their questions in the text on the back of the lithograph. When they complete that task, ask them to decide if each of their questions was answered completely, answered partially, or not answered at all. Go through the original list and place an "A" in front of the questions that were answered completely, a "P" for those that were partially answered, and an "N" for those that were not answered at all. Determine if the most commonly asked questions were also answered completely. Encourage students to do further research to find answers to the unanswered questions.

A content reading tool. Have students read the text on the lithograph and then write a quiz for the class.
