When the human being discovered that the planet he inhabited was not alone in the universe, he had an enormous eagerness to know how everything around the earth was shaped. Astronomy had philosophers of the scope of Aristotle, one of its promoters . Then he was followed by men who transformed the vision of the space we inhabit. Galileo Galilei, Johannes Kepler, Nicolás Copernicus, are some of the names that have stood out in the study of the cosmos. Many of them even had to confront the prevailing conceptions of their time, to the point of becoming almost marginal. Today, astronomy has become a science with a deep life of its own.
The section that the WhatAsker dedicates to astronomy , has definitions, theories and laws . Here you will be able to know the different bodies that inhabit the universe: planets, stars, comets, satellites, the laws that govern their movements , as well as introducing us to the trips that have allowed us to expand the frontiers of knowledge of the universe. In each topic addressed, readers will be able to find excellent graphic material that allows them to expand their knowledge.
Temperatures so high occur inside the Sun that they generate nuclear-type reactions and that in turn create energy. This energy is released in the form of solar radiation. Radiation emissions have varying degrees of intensity. Not all this radiation reaches planet Earth, as some waves (the most damaging) are filtered or absorbed by atmospheric gases, especially ozone. The solar radiation … Read more
The Solar System has eight planets, five mini-planets (dwarfs), comets, and asteroids. The solid celestial bodies that revolve around them are called natural satellites, since they are not created by man. The natural satellite of the Earth is the Moon, but there are other celestial bodies that have been given their own names. They come in different sizes and shapes, … Read more
A planet is a celestial body that is characterized by having a spherical shape and by not having its own light. They revolve around themselves and usually around a star. There are several planets that make up our Solar System and among them we have planet Earth , a rocky planet. Gravity: 9.780327 m / s² Orbital period: 365.256363004 days What is planet Earth?

The astronomy is a science that is responsible for studying all celestial bodies in the universe and within the various astronomical events that occur in the sky are also studied. One of these important events is the solstice , which is the indicator of the onset of winter or summer. What is the solstice? The solstice is one of the best-known astronomical events that occurs only twice … Read more
The astronomical events are closely related to astronomy and there are many of them, which are attention and study to humans. One of the most important is known as the equinox , a specific time that occurs in the year in which day and night have the same duration . The word comes from Latin, from the word “aequinoctium” which means “equal night“. What is the equinox? The equinox is an astronomical event that happens … Read more
Many instruments have been created and manufactured with the aim of being able to study and analyze what happens in space. One of these objects is known by the name of radio telescope , a very important device that makes it possible to capture the different radio waves that are transmitted by all celestial bodies . It should be noted that radio waves … Read more
