Photo taken by the Hubble Space Telescope

This image, called the Hubble Deep Field, was produced by combining 276 of the 342 exposures taken over a period of ten days. Hubble reached back 10 billion years to capture a view of young, never-before-seen galaxies in various stages of evolution.

Facts of interest about the image

Text features background information and an image of part of the field showing elliptical and spiral galaxies.

Description

This is an image of the Hubble Deep Field, which was produced by combining 276 of the 342 exposures taken over a 10-day period. Hubble reached back 10 billion years to capture a view of young, never-before-seen galaxies in various stages of evolution. The lithograph also features background information and a close-up image of a portion of the field that contains elliptical and spiral galaxies.

How to use in the classroom

Teachers can use this lithograph as:

An engagement tool in an inquiry-based lesson. Have students study the image side of the lithograph. Ask them to write down any questions they have about the image. 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 back of 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 back of 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 on the board or overhead. 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 completely answered. Encourage students to do further research to find answers to the unanswered questions.

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

A source of information. Have students use the labeled diagram on the back of the lithograph to learn about spiral and elliptical galaxies.
