Space telescopes are some of the most precise and complicated machines ever built. Not only must they survive the harshness of space travel, but they also need to be incredibly accurate: misalignments by fractions of a millimetre can have huge effects on the quality of the images they capture. In 1990, the Hubble Space Telescope became the first…

A simple mistake in properly setting up a measuring device caused millions of dollars to be spent in correcting the initial optical failure of the Hubble Space Telescope (HST). This short article is intended as a lesson for a physics laboratory and discussion of errors in measurement.

An innate advantage for astronomy teachers is having numerous breathtaking images of the cosmos available to capture students' curiosity, imagination, and wonder. Internet-based astronomy image libraries are numerous and easy to navigate. The Astronomy Picture of the Day, the Hubble Space Telescope image archive, and the NASA Planetary…

Equally as important as growing the body of human knowledge through scientific discoveries and analysis is relaying this information to the general public in a digestible manner to establish a scientifically literate society. This dissertation approaches the multifaceted issue by combining an in-depth study of brown dwarf binary atmospheres with…

Artificial satellites are easily observed most nights when the weather is fine. The website called "Heavens Above" at www.heavens-above.com will help locate these satellites flying over one's location. It also includes how bright they will appear. The direction of travel of each satellite in the night sky also indicates the type of satellite. For…

Listed are 27 references about the Hubble Space Telescope project. Included are nontechnical books, nontechnical articles, and technical articles. (CW)

Presents guiding principles for developing interactive lessons for the World Wide Web. Describes "Amazing Space: Education Online from the Hubble Space Telescope", a program where students study spectacular Hubble Space Telescope images of stars and star-forming regions to learn about the life cycle of stars and the creation of atoms. (JRH)

Describes the objective of the Hubble Space Telescope, the equipment on board, and how repairs have been made on the telescope. Presents examples of the main results achieved so far. (JRH)

Presented is the best understanding of the flaw discovered in the optics of the Hubble Space Telescope and the possible solutions to the problems. The spherical aberration in the telescope's mirror and its effect on the quality of the telescope's imaging ability is discussed. (CW)

Classroom debates used to be familiar exercises to students schooled in past generations. In this article, the authors describe the technique called "intimate debate". To cooperative learning specialists, the technique is known as "structured debate" or "constructive debate". It is a powerful method for dealing with case topics that involve…

Describes how the Hubble Space Telescope works and how scientists repaired the spherical aberration that caused a reduction in image quality. (ZWH)

The Hubble Space Telescope project is described. Discussed are the project directors, construction, launch, deployment, hazards, rationale, and hope of the project. (CW)

The Hubble Space Telescope, the most complex and sensitive optical telescope ever made, was built to study the cosmos from low-Earth orbit for 10 to 15 years or more. The Compton Gamma Ray Observatory is a complex spacecraft fitted with four different gamma ray detectors, each of which concentrates on different but overlapping energy range and was…

Describes some of what a science teacher learned while participating in an amateur observing program that provided access to the Hubble Space Telescope. (ZWH)

Provides information on the problems with the Hubble Space Telescope and how the National Aeronautics and Space Administration is trying to fix it. Includes a student quiz and possible student outcomes. (JOW)
