WebThe electromagnetic spectrum includes X-rays. As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy. We usually talk about X-rays in terms of their energy rather than wavelength. This is partially because X-rays have very small wavelengths!

The photons are directed onto the detector where they are absorbed, and the energy, time, and direction of individual photons are recorded. Such measurements can provide clues about the composition, temperature, and density of distant celestial environments. eastlink mobility login

WebX-ray telescopes must be very different from optical telescopes. Because of their high-energy, X-ray photons penetrate into a mirror in much the same way that bullets slam into a wall. Likewise, just as bullets ricochet when they hit a wall at a grazing angle, so too will X-rays ricochet off mirrors. WebAn X-ray telescope (XRT) is a telescope that is designed to observe remote objects in the X-ray spectrum. In order to get above the Earth's atmosphere, which is opaque to X-rays, X …

X-ray astronomy is an observational branch of astronomy which deals with the study of X-ray observation and detection from astronomical objects. X-radiation is absorbed by the Earth's atmosphere, so instruments to detect X-rays must be taken to high altitude by balloons, sounding rockets, and satellites. X-ray astronomy uses a type of space telescope that can see x-ray radiation which standard optical telescopes, such as the Mauna Kea Observatories, cannot. WebAn optical telescope consists of two main elements: the objective, which focuses light rays together to form an image of a distant object, and the eyepiece, which acts like a magnifying glass to provide an enlarged view of the image formed by the objective. The eyepiece consists of a lens or combination of lenses.
