Astronomy is a science that studies everything outside of the earth's atmosphere
astronomy, science that encompasses the study of all extraterrestrial objects and phenomena. Until the invention of the telescope and the discovery of the laws of motion and gravity in the 17th century, astronomy was primarily concerned with noting and predicting the positions of the Sun, Moon, and planets, originally for calendrical and astrologic.
Since the late 19th century, astronomy has expanded to include astrophysics, the application of physical and chemical knowledge to an understanding of the nature of celestial objects and the physical processes that control their formation, evolution, and emission of radiation. In addition, the gases and dust particles around and between the stars have become the subjects of much research. Study of the nuclear reactions that provide the energy radiated by stars has shown how the diversity of atoms found in nature can be derived from a universe that, following the first few minutes of its existence, consisted only of hydrogen, helium, and a trace of lithium. Concerned with phenomena on the largest scale is cosmology, the study of the evolution of the universe. Astrophysics has transformed cosmology from a purely speculative activity to a modern science capable of predictions that can be tested.
Astronomy is a physical science concerned with the smallest particles and the largest natural objects. The name Astronomy comes from the Greek roots Astr- and -nomia to literally mean "name stars". Astronomy is the study of everything outside of the earth's atmosphere and their chemical and physical properties.
astronomy noun. The study of the physical universe beyond the Earth's atmosphere

What exactly is astronomy? Astronomy is a physical science concerned with the smallest particles and the largest natural objects. The name Astronomy comes from the Greek roots Astr- and -nomia to literally mean "name stars".
Unlike astronomy, astrology cannot be described as an exact science. I've always had an interest in astronomy. These ancient scholars were steeped in poetry and painting, as well as maths and astronomy. Unfortunately he is not entirely clear about how he understands the relationship between the treatments of astronomy and geometry.
Astronomy (from Greek: ἀστρονομία) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets.

Pattern of stars recognized on Earth's night sky
An asterism is an observed pattern or group of stars in the sky.Asterisms can be any identified pattern or group of stars
And therefore are a more general concept than the 88 formally defined constellations.Constellations are based on asterisms
But unlike asterismsConstellations outline and today completely divide the sky and all its celestial objects into regions around their central asterisms.For example
The asterism known as the Big Dipper comprises the seven brightest stars in the constellation Ursa Major.Another is the asterism of the Southern Cross
Within the constellation of Crux.
Interstellar absorption and scattering of light

Astronomy written in Hebrew or by Hebrew speakers
Hebrew astronomy refers to any astronomy written in Hebrew or by Hebrew speakers
Or translated into Hebrew
Or written by Jews in Judeo-Arabic.It includes
A range of genres from the earliest astronomy and cosmology contained in the Bible
Mainly the TanakhTo Jewish religious works like the Talmud and very technical works.
The modern constellation Orion lies across two of the quadrants
Symbolized by the White Tiger of the West and Vermilion Bird of the South
That divide the sky in traditional Chinese uranography.
According to traditional Chinese uranography
The modern constellation Taurus is located within the western quadrant of the sky
Which is symbolized as the White Tiger of the West (西方白虎).
