NASA ) The first of NASA's three High Energy Astronomy Observatories, HEAO 1 was launched aboard an Atlas Centaur rocket on 12 August 1977 and operated until 9 January 1979. During that time, it scanned the X-ray sky almost three times over 0.2 keV - 10 MeV, provided nearly constant monitoring of X-ray sources near the ecliptic poles, as well as more detailed studies of a number of objects through pointed observations. 2-Telescopes Large Interferometer ( GI2T REGAIN ) Active Magnetospheric Particle Tracer Explorers ( AMPTE ) Advanced Camera for Surveys ( ACS ) The Advanced Camera for Surveys (ACS) will be installed in the Hubble Space Telescope (HST) during a Space Shuttle mission scheduled in 2000. ACS will increase the discovery efficiency of the HST by a factor of ten. ACS will consist of three electronic cameras and a complement of filters and dispersers that detect light from the ultraviolet at 1200 angstroms to the near infrared at 10,000 angstroms.

Telescopes Chapter index in this window Chapter index in separate window This material (including images) is . See my for fair use practices. Men and women have looked up at the sky and wondered about the things they see up there for as long as humans have lived on our Earth. Long ago, the Sun and Moon were mysterious objects that could be seen in the day and night. But the planets and stars were even more mysterious probably because they are so far away that we could only see them as points of light. Unlike the things on the Earth that we can study up close, handle, listen to, smell, and taste, the only thing ancient watchers of the sky had to learn about things in space was their eyes and imaginations. Only very recently in the history of humanity have astronomers been able to extend the reach of our eyes (and our imaginations!). Galileo pioneered modern explorations in the early 1600's by using a device originally invented for naval operations to explore the heavens. The device he used, of course, was the telescope , an instrument used to gather and focus light. Our atmosphere prevents most of the electromagnetic radiation from reaching the ground, allowing just the visible band, parts of the radio band, and small fractions of the infrared and ultraviolet through. Our eyes can detect the visible (optical) band, so the early telescopes were all built to observe in that part of the electromagnetic spectrum. It wasn't until the 1930's that astronomers began observing with another part of the electromagnetic spectrum-the radio band. The development of space technology has enabled astronomers to put telescopes above the atmosphere and explore all of those places out there using the full range of the electromagnetic spectrum. This chapter covers the basics of telescopes and the effects of the atmosphere on images. Vocabulary terms are in

All About Telescopes The telescope was one of the very first tools ever used to study outer space. This ability to see an image in space magnified has lead to countless discoveries in astronomy, beginning with the early and complicated classification of the planets , the Sun , the stars and beyond. Early versions of what we now know as the telescope date as far back in time as the 10th century, though modern publicized recognition is usually given to an unknown English spectacle maker around 1600. In 1609, Galileo Galilei constructed his own version of the tool, and is typically credited with being the first to use the telescope for the purpose of astronomy. Galileo’s creation is now known as the Galilean telescope. All modern telescopes are generally classified into two main categories, optical telescopes and radio telescopes. An optical telescope, which is the most common, can be separated into three types; the Galilean refracting telescope, the Newtonian reflecting telescope, and the Catadioptrics telescope. The optical telescope works by utilizing one or more curved optical lenses or mirrors to gather light and electromagnetic radiation, then bringing that light or radiation into focus, making objects that are actually great distances away appear to be much closer.
