By studying electromagnetic emissions, astronomers hope to come to a better understanding of the Universe. There are many puzzles in the universe that can only be solved by comparing images...X Ray Telescopes
Our best articles related to X ray telescopes
X-ray telescopes can use a variety of different designs to image X-rays. The most common methods used in X-ray telescopes are grazing incidence mirrors and coded apertures. The limitations of X-ray optics result in much narrower fields of view than visible or UV telescopes. The utilization of...

Galileo Galilei was the first person known to have turned a telescope to the heavens and to record what he saw. Since that time, observational astronomy has made steady advances with each improvement in telescope technology. A traditional division of ...
The term balloonist usually refers to someone who rides in a balloon. Perhaps those who use balloons for exploration and research are best referred to as a ballooner. Jeffrey Alan Hoffman Jeffrey Alan Hoffman, Ph.D. (born November 2, 1944) is ...
Dr. Gursky’s research activities have concentrated in the area of x-ray astronomy. He has published more than 100 articles in this area and has edited two books on the subject. He was the Principal Investigator for NASA sponsored space programs ...
The majority of astrophysical observations are made using the electromagnetic spectrum. * Radio astronomy studies radiation with a wavelength greater than a few millimeters. Radio waves are usually emitted by cold objects, including interstellar gas and dust clouds. The cosmic ...
Indian space era dawned when the first two-stage sounding rocket was launched from Thumba in 1963. However even before this epoch making event, noteworthy contributions were made by the Indian scientists in the following areas of space science research: * ...
After galaxies external to the Milky Way were found to exist, initial observations were made mostly using visible light. The peak radiation of most stars lies here, so the observation of the stars that form galaxies has been a major ...
During its High Energy Astronomy Observatory program in 1977, NASA announced plans to build a “great observatory” for gamma-ray astronomy. The Compton Gamma-Ray Observatory (CGRO) was designed to take advantage of the major advances in detector technology during the 1980s, ...
