A head-on collision between two galaxies located 500 million light-years away in the constellation Sculptor. The blue ring of the large galaxy is a collection of newly formed stars. A shock wave rippled through the large galaxy when the smaller one punched through it. This shock wave triggered a circular wave of star formation. Image: Kirk Borne (STScI) and NASA

Introduction

Since humans first saw the stars we have had an overwhelming curiosity about space and space travel. For us to fully appreciate the accomplishments of current space research such as the Hubble Space Telescope and the Mars Explorer we must explore the rich history of astronomy and space research. Libraries and the ability to connect to the internet sites of NASA, universities and private research organizations provide the tools required to access both rich data that includes both graphic and text.

The Task

Resembling an aerial fireworks explosion, this dramatic picture of the energetic star WR124 reveals it is surrounded by hot clumps of gas being ejected into space at speeds of over 100,000 miles per hour. The massive, hot, central star is known as a Wolf-Rayet star. This extremely rare and short-lived class of super-hot star is going through a violent transitional phase. The star is 15,000 light-years away, located in the constellation Sagittarius. Image: NASA

Your team's mission is to select a topic related to astronomy, space exploration, or space travel, research that topic from a historical stand point and create an electronic timeline that describes the development of the topic throughout history.

The Process

The Hubble Space Telescope (HST) is a space-based observatory roughly the size of a school bus, and orbits 600 kilometers above the Earth. A telescope in space allows astronomers to observe objects without interference from the Earth's atmosphere. Since 1990 the HST has produced some of the most spectacular astronomical images to date.

  1. Participate in the Library Orientation Session
  2. Each team will select one of the example topics shown in the Table of Example Topics or another topic related to astronomy, space research, space travel or a related topic. Only one team may work on each topic and the topic must be approved by the instructor
  3. Each team member should select an initial job function to perform. These functions include:
    • Two team members should search the MTC Library for data.
    • Two team members should search the internet for data.
    • One team member should begin formatting the timeline and, as information is found, be the editor of the timeline.

Continue to information until lunchtime. Switch roles so everybody gets a chance in each role.

  1. After lunch edit the timeline as a team and prepare to present your results to the other teams.

Conclusion

This original artwork depicts the Pioneer-Venus probe entering Venusian atmosphere. When the probe hit the atmosphere it glowed, which is a similar reaction as when meteorites hit the Earth's atmosphere. The bus of Pioneer did not carry a heat shield, therefore the artist's illustration is a more spectacular image. As a result of not possessing a heat shield, the Pioneer eventually burned up completely after being confronted with the atmosphere. Image: Don Davis and NASA

The future of space exploration is exciting and lets us use our imaginations. As we venture into the future and space lets not forget the past that got us here.
