Astrophysical Sciences

The universe consists of space and time as well as their varying contents, which include planets, stars, protoons, and all other kinds of energy and matter. The Big Bang theory is the most accepted cosmological model of the evolution of the universe. This cosmology outlines the beginning of the universe, with its dense, hot, fast, ionized stuff (atoms) and later became cool, slow, dense, and less heated and less ionized, as the universe continued to evolve. 

Astronomy is the study of celestial bodies like the moon, comets, planets, and stars.

Astronomy mainly concerns itself with the study of celestial bodies, which it determines from their relative movement with respect to the fixed nucleus, and the effect that heavenly bodies have on terrestrial elements through their gravitational waves. Astronomy is an ancient and essential science that has developed over the ages, owing to the rise and developments of astronomy during the historical period referred to as the Pre-Celfth Quadrant, when most of the European telescopes were invented. The rise of the Muslim Empire in the 12th century led to the establishment of the first telescopes. The development of the Arabic language also facilitated the introduction of telescope technology. Later, European scientists made major contributions to the discovery of the laws of gravity, which are primarily responsible for the creation of the planets. The main areas of development of astronomy are:

Astrology is a branch of sciences that studies celestial bodies and human events on earth. 

It describes the relationship between heavenly bodies and humans, such as birth, death, birthdays, marriages, and political affairs. The best time for these events to occur depends on what the astronomers are expecting to happen. There are various theories concerning the working of the gravitational waves. Two competing theories are the Doppler theory and the B-ray theory.

Astrography is the study of the visible universe around us through telescopes. 

The best known example of an astrograph is the telescope used by Carl Einstein in 1900. This apparatus was used to observe Einstein’s theory of relativity by using fixed rods. The visible universe consists of faraway celestial bodies that cannot be seen by human eyes. Astronomers use telescopes to view these distant objects.

Galaxy Formation. One of the most common theories of the universe is the idea of a flat universe.

This describes how the distribution of matter in space remains unaltered despite the presence of massive rotating disks that tend to pull the gas clouds around them into smaller and further apart regions. Astronomers use sophisticated instruments such as the Very Large Telescope (VLT) to observe the distribution of gas in galaxies.

Dark Energy:

Einstein’s theory of relativity implies that the universe contains vast amounts of invisible matter that makes up a great portion of the universe’s total energy. By observing the movement of this matter, astronomers hope to learn about the makeup of the very powerful and dense black holes that are forming in galaxies. By tracking the movement of dark matter, astronomers hope to find signs of the presence of a super giant and a host of other dark energy generators in our very crowded galaxy.

Astronomy also tells us about the composition of our own planet. 

Because our solar system is made up of rocky objects, primarily carbon, astronomers can calculate the amount of normal matter (also known as “metals”) in the planetary system. The calculation, based on the distribution of elements such as iron, shows that a solid planet like Earth must be filled with a great deal of ordinary matter. On the other hand, if the planet were filled with nothing but hydrogen (a type of gas), the calculations would show that the planet would be nothing more than hot rock (or “ice”).

Astronomy and cosmology are two of the basic understandings of how the universe works. The big question remains, however. How will the expanding universe affect our present understanding of it? Will we eventually have better tools to study the universe in its entirety? Some experts believe that we may already have an answer to that question, though others are less optimistic.
