The history of astronomy marked Galileo’s use of the telescope as signifying the event where the instruments were used for astronomical purposes and made famous through discoveries of heavenly bodies. Before Galileo’s use of the telescope, nobody had the initiative to use…
from the telescope he made, he published relevant discoveries in the Sidereus Nuncius in March of 1610 which gained increasing interests from various scholars in the field of astronomy.
Putting telescopes in space have the following advantages compared with the use of ground-based telescopes: (1) the lack of atmosphere, which makes it possible to see things in space that are otherwise blocked at certain wavelengths when trying to view them from the ground; (2) going out into space reduces the temperature at which the telescope operates, further improving image resolution and the performance of the detector arrays and other optoelectronic devices on board; and (3) it is much darker in space than it is on the ground, which makes it easier to see objects that are far away (PennWell Corporation, 2004, pars. 3 & 4).

The NASA define a dwarf planet as “a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite” (NASA, 2010, par. 3). Pluto was reclassified by the IAU as a dwarf planet because of the provision: it has not “cleared the neighborhood” around its orbit; meaning “as planets form, they become the dominant gravitational body in their orbit in the Solar System. As they interact with other, smaller objects, they either consume them, or sling them away with their gravity. There are still many objects with similar size and mass to Pluto jostling around in its orbit. Until Pluto crashes into many of them and gains mass, it will ...

Profound ideas point out life as an indefinable concept that ironically can be explained in various contexts and subjective to the person describing it. It is very confusing enough that defining life as the opposite of death makes it more puzzling. Physicists describe living opposed to non-living in terms of the molecules that constitute the entities.
“However, considering the fact that the solar system began as a cloud of gas and dust that was near absolute zero we might wonder where the earths internal heat came from to drive the plate tectonics.” (The Heat History of Earth) It is a confusing question for the
In ancient civilizations constellations were used for astrology or myths. Astrology is where stars and planets are tracked in order to predict an individual or society’s future. Constellations like Orion, Mars, and Jupiter
ve argument, the theory has changed adversely from molecular to atomic nature, from low to high acceptance, from knowledge to better information on the nature of the atoms. Evolution theory has been known to address the changes in the world systems over time.
People who study the stars also known as the Astronomers have come up with fascinating facts that molecular clouds which comprises of the thick dust and the gases are the birth place of stars .Once the hydrogen gas
Astronomy is classified as a natural science that included the study of celestial objects such as stars, moon, planets, galaxies and nebulae. In addition, it also deals with the physics, chemistry, and the objects evolution, and phenomena that originate outside the earth’s atmosphere.
