Dec 11, 2018 · Cameras use lenses to focus light onto a detector (like CCDs or film) to capture a picture. Telescopes like Hubble take images of objects in the cosmos. However, X-rays are so energetic (and have such a small wavelength) that they tend to pass through most things, including mirrors.
Dec 11, 2018 · The best way for astronomers to increase their ability to detect weaker X-ray sources was to develop ways to image the X-ray sky. Similar to the way an optical telescope increases our eye's ability to see faint stars, an X-ray telescope can concentrate the light from an X-ray star onto an electronic eye.
X-ray telescope, instrument designed to detect and resolve X-rays from sources outside Earth’s atmosphere. Because of atmospheric absorption, X-ray telescopes must be carried to high altitudes by rockets or balloons or placed in orbit outside the atmosphere.
An X-ray telescope (XRT) is a telescope that is designed to observe remote objects in the X-ray spectrum. X-rays are absorbed by the Earth's atmosphere , so instruments to detect X-rays must be taken to high altitude by balloons , sounding rockets , and satellites .
Nov 17, 2014 · By looking at the sky with X-ray and gamma-ray instruments, we collect important information in our attempt to address questions such as how the universe began and how it evolves, and gain some insight into its eventual fate.

X-ray telescopes provide an unequaled view of super- heated matter that is swirling toward the event horizon of a black hole. Stellar Black holes with a mass of about 5 - 100 Suns formed at the end of very massive star's evolutionary cycle.
