Who invented astronomy?
Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas.
What is the meaning of Astro Science?
Astronomy (from Greek: ἀστρονομία) is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. … Astronomy is one of the oldest of the natural sciences.

What is an X-ray telescope?
An 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-ray telescopes must be mounted on high altitude rockets, balloons or artificial satellites .
What is the X-ray telescope mirror configuration?
The simplest X-ray telescope mirror configuration is a paraboloid of revolution, in which X-rays along the axis of the paraboloid can be brought to a focus by scattering at near-grazing incidence from the surface of the reflector. This type of X-ray mirror was used on the SAS-2 ( Copernicus) satellite.
What is the history of X-ray astronomy?
In the 1970s, dedicated X-ray astronomy satellites, such as Uhuru, Ariel 5 , SAS-3, OSO-8 and HEAO-1 , developed this field of science at an astounding pace. Scientists hypothesized that X-rays from stellar sources in our galaxy were primarily from a so-called "X-ray binaries."
Why are X-ray telescopes not as good as optical telescopes?
Although the spatial resolving power of a telescope depends inversely on photon wavelength, the practical difficulty in bringing X-rays to focus means that the spatial resolution of X-ray telescopes is generally much worse than for an optical telescope of similar collecting area.
