Basic Astronomy: Everything you need to know

Basic Astronomy: Everything you need to know

The basic astronomy is the science that dominates the study of the astral entities of the cosmos, including the Stars and their satellites, stars and interstellar matter, kites and meteoroids, dark matter systems, vapor and particles called nebulae and nebula clusters; So he studies his currents and the anomalous ones tied to them.

Their investigation and the inquiry of their origin come from the research that comes from them through electromagnetic irradiation or any other contour. The basic astronomy has been tied to the human being since prehistory and all the progress has been related to this science. It is one of the scarce sciences in which the likes can still play a diligent role, fundamentally in the finding and tracing of anomalous like orbits of light of inconstant stars, revelation of Planetoids, Kites, among others.

History of the basic astronomy

In almost all the old cults was the cosmogony, which intended to expose the beginning of the universe, tying this to the traditional compendiums. The story of the basic astronomy is as archaic as the history of the human being. Years ago it was conquered, exclusively, of the reflection and predictions of the currents of the essences perceptible to the naked eye, being left aside for a long period of the physics.

The ancient Greeks created significant taxes on the basic astronomy, including the thesis of dimension. Pre-Columbian astronomy had very punctual calendars was one of those that possessed more punctuality with some famous buildings like the pyramids of Egypt.

In spite of the common faith, the Greeks knew about the roundness and curvature of our planet. It was not clueless for them that the darkness of the Earth planned on the moon was spherical, nor that its surface is understandably void since, among other motives, the same stars do not appear in the parts of the Mediterranean.

In the Aristotelian standard the celestial concerned perfection-“beautifully resounding spatial bodies bustling in perfect round orbits”-while terrestrial was anomalous; These two domains were considered as confronted. Aristotle protected the geocentric hypothesis to deploy its propositions. It was possibly eratosthenes who plotted the armillary sphere which is a atacir to expose the supposed current of the stars near the earth.

The basic theoretical astronomy

Theoretical astronomers wield a great diversity of equipment such as accurate methodical models and computer numerical pretenses. Each one possesses its advantages. The analytical mathematical patterns of a summary are usually better as they manage to get to the heart of the difficulty and expose better what is happening. The numerical pilots can discover the existence of anomalous and furniture that otherwise would not be distinguished.

The theorists of the basic astronomy put their verve in founding theoretical patterns and suppose the observational results of these patterns. This helps viewers find chips that can challenge a standard or agree to opt for various experimental alternates or even counter.

Theorists, in the same way pretend to create or change models to obtain new data. In the case of a softness, the current propensity is to try to make minimal reforms to the model so that it is incumbent with the antecedents. In some cases, a large amount of fragile data over time can lead to a general planting of a test.

The topics learned by hypothetical astronomers contain: stellar hacendosa and stellar progress; Nebula Alignment; Principle of universal rays; Current relativity and physical cosmology, containing threads hypothesis.

Characteristics of the basic astronomy

The basic astronomy is the science that is invaded of the thesis of the Stars of the universe, necessarily of the laws that send the current of the same. Observers assimilate the distribution and progress of stars, stars, ensembles and other sidereal essences.

However, it began with the simple visual information of Astros and stars, in the novelty the basic astronomy collaborates with other squares of the science the empirical systematics and essences of study, of which it is necessary to underline the geology and astral climatology, the Nuclear physics, electronics and astral Navigation.

It is one of the few wisdoms in which the likes can still rescue a dynamic role, fundamentally in the finding and tracing of anomalous like orbits of light of changeable stars, unveiling of Planetoids and kites among others.

Branches of the basic astronomy

Because of the width of the essence of study the basic astronomy is divided into unequal in the following offspring:

Position astronomy

It is the oldest branch of this science; It has as its object to place in the celestial globe the perspective of the stars measuring fixed angles in relation to essential planes, wieldinging for it unequal systems of astronomical axes. Together, it narrates the supposed current of the same in the Celestial dome and other anomalous ones like the eclipses and circulations of the Stars by the disc of the sun. They are essential tasks of the same the cost of the time and the value for the navigation of the geographical axes.

Celestial mechanics

Study the current of the worlds under the exercise of the force of gravity. Among the gains are the handling of many difficulties of the basic astronomy as: the complex wiggle of the moon near the Earth, the riots in the current of Uranus produced by the planet Neptune, the automation of the orbit of many kites and Differences in the perihelion of mercury derived by the gravitational authority of the Astro King.

Astrophysics

It is the branch of the basic astronomy that assimilates the Constitution, distribution and progress of the cosmos, began in the nineteenth century, when thanks to the Wraith could discover the chemical constitution of the stars. The branches of physics involved in this are nuclear physics (reproduction of energy in the intimate zone of the stars) and the current theory of relativity.

Cosmology

It is the branch of the Astral Science that learns the principles, distribution, progress of the observable cosmos.

Fields of study of the basic astronomy

Among the changes of studies that are highlighted in the basic astronomy, we have:

Extragalactic Astronomy

The portrait shows several blue essences with ring representation, which are multiple iconographies of the same nebula, reproduced by the consequence of the gravitational lens 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 essences more secluded.

Astrometrics

Study the perspective of the essences in the sky and the change of focus. It requires the axis system used and the movement of the objects in the Milky Way, which is the nebula to which the Solar system concerns.

 

 

Discrepancy between astronomy and astrology

You should not be involved in basic astronomy with astrology. Although both collaborate a common principle, they are very unequal. Astronomy is a science since scientists pursue the scientific method and astrology presents besides the Astroquimica, which is invaded of the conjectured authority of the cosmos in the life of the human beings, is a pseudoscience the soothsayers follow a system of unexperienced or clearly mistaken dogmas; For example, they do not consider the reticence of the equinoxes, a finding that is bred Hipparchus de Nicea.
