The human understanding of the cosmos beyond Earth has grown after inventing specialized equipment such as x-ray telescopes.
<h3>What is
x-ray telescopes?</h3>
X-ray telescope, a device made to find and focus X-rays from sources beyond the atmosphere of Earth.
Some key features regarding the x-ray telescope are-
- X-ray telescopes have to be launched into orbit outside of the atmosphere or propelled to great heights by rockets and balloons due to atmospheric absorption.
- While telescopes carried aloft using rockets or satellites serve to detect softer radiation, balloon-borne telescopes may catch the more piercing (harder) X-rays.
- That sort of telescope must have a completely different design from a typical optical telescope.
- Since X-ray photons are so energetic, a typical reflector's mirror wouldn't be able to stop them from passing through.
- If X-rays are to be collected, they must bounce off a reflector at an extremely low angle.
