La basic astronomy It is the science that dominates the study of the astral entities of the cosmos, including the stars and their satellites, stars and interstellar matter, comets and asteroids, systems of dark matter, vapor and particles called nebulae and clusters of nebulae. ; so he studies their currents and the abnormals tied to them.
Their research and the investigation of their origin come from the research that comes from them through electromagnetic irradiation or any other contour. The basic astronomy It has been tied to the human being since prehistory and all progress has been related to this science. It is one of the few sciences in which those who like it can still play a diligent role, fundamentally in the discovery and tracking of anomalies such as inconstant starlight orbits, revelation of planets, comets, among others.
History of basic astronomy
In almost all the old cults there was the cosmogony, which claimed to expose the beginning of the universe, tying this to traditional compendia. The history of the astronomy Basic knowledge is as archaic as human history itself. Years ago, it was achieved exclusively through reflection and predictions of the currents of essences perceptible to the naked eye, remaining outside the realm of physics for a long time.
The ancient Greeks created significant taxes on basic astronomy, including the dimension thesis. The astronomy Pre-Columbian times had very punctual calendars; it was one of the most punctual, with some famous buildings like the pyramids of Egypt. You can also explore more about the ancient astronomy to understand its evolution.
Despite common faith, the Greeks knew of the roundness and curvature of our planet. The fact that the darkness of the planned Earth on the Moon was spherical, nor that its surface is understandably annular since, among other reasons, the same stars do not appear in parts of the Mediterranean, did not go unnoticed for them.
In the Aristotelian standard the celestial concerned perfection - "beautifully rotund space bodies bobbing in perfect round orbits" - while the terrestrial was anomalous; These two domains were reflected as opposed. Aristotle protected the geocentric hypothesis to unfold his propositions. It was possibly Eratosthenes who traced the armillary sphere, which is an attack to expose the supposed current of the stars near the earth.
Theoretical basic astronomy
Theoretical astronomers use a wide variety of equipment, including precise methodological models and computer numerical simulations. Each has its advantages. Analytical mathematical models of a summary are generally better, as they get to the heart of the difficulty and better expose what is happening. Numerical pilots can uncover the existence of anomalies and features that would otherwise go unnoticed. Furthermore, in the history of basic astronomy, the work of theorists is essential.
Theorists of basic astronomy they put their energy into founding theoretical patterns and assuming the observational results of these patterns. This helps viewers to search for cards that can challenge a standard or agree to choose between several alternate or even contrary experimental ones.
Theorists, likewise, seek to create or change models to obtain new data. In the case of softness, the common tendency is to try to make minimal modifications to the model to make it fit with the priors. In some cases, a large accumulation of weak data over time can lead to the failure of a test altogether.
Topics learned by hypothetical astronomers include: stellar achievement and stellar progress; nebula alignment; principle of the universal rays; current relativity and physical cosmology, containing string hypotheses.
Characteristics of basic astronomy
La basic astronomy It is the science that is invaded by the thesis of the stars of the universe, necessarily of the laws that command their current. The observers assimilate the distribution and progress of the stars, heavenly bodies, groups and other sidereal essences.
However, it started with simple visual information about stars and celestial bodies, in the new basic astronomy collaborates with other places in science on empirical systematics and study essences, among which it is worth highlighting Astral Geology and Climatology, Nuclear Physics, Electronics and Astral Navigation.
It is one of the few wisdoms in which the liked can still play a dynamic role, primarily in finding and tracking abnormalities such as shifting starlight orbits and Comets among others.
Branches of basic astronomy
Due to the width of the essence of study the basic astronomy is divided into unequals in the following offspring:
position astronomy
It is the oldest branch of this science; Its purpose is to place the perspective of the stars on the celestial globe by measuring fixed angles in relation to essential planes, wielding unequal systems of astronomical axes for this purpose. Together, it narrates the supposed current of the same in the celestial dome and other anomalous ones such as eclipses and circulations of the stars through the disk of the Sun. The cost of the hour and the value for the navigation of the axes are essential tasks of the same. geographical.
celestial mechanics
He studies the current of the worlds under the exercise of Force of gravity. Among the gains, the processing of many difficulties of the basic astronomy such as: the complex wobble of the Moon near the Earth, the revolts in the Uranus current produced by the planet Neptune, the automation of the orbit of many comets and the differences in the perihelion of Mercury derived by the gravitational authority of the star king .
Astrophysics
It is the branch of basic astronomy that assimilates the constitution, distribution and progress of the cosmos, it begins in the XNUMXth century, when thanks to the spectra the chemical constitution of the stars could be discovered. The branches of physics involved in it are Nuclear Physics (reproduction of energy in the intimate area of stars) and the current Theory of Relativity.
Cosmology
Is the branch of astral science that learns the principles, distribution, progress of the observable cosmos.
Fields of study of basic astronomy
Among the changes of studies that stand out in basic astronomy, we have:
extragalactic astronomy
The portrait shows various blue essences with ring representation, which are multiple iconographies of the same nebula, reproduced by the gravitational lensing consequence of the group of yellow nebulae on the axis of the photograph. The lens is caused by the gravitational field of the whole that orbits the light, increasing and deforming the painting of more distant essences.
astrometry
Study the perspective of the essences in Heaven and the change of focus. It specifies the axis system used and the movement of objects in the Milky Way, which is the nebula to which the Solar System is concerned..
Discrepancy between Astronomy and Astrology
should not be involved in basic astronomy with Astrology. Although both collaborate on a common principle, they are very different. Astronomy is a science since scientists pursue the scientific method and astrology also presents the astrochemistry, which is invaded by the conjectured authority of the Cosmos in the life of human beings, is a pseudoscience, the diviners follow a system of dogmas not experienced or clearly wrong; for example, they do not take into account the reticence of the equinoxes, a finding that is brought up to Hipparchus of Nicaea.
