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.
Aristarchus of Samos was one of the oldest mathematicians and astronomers of ancient Greece. He proposed a quite revolutionary astronomical hypothesis for his time. He said that the Sun, not the Earth, was the fixed center of the universe and the Earth , along with the rest of the planets revolved around the sun . He also said that the stars were distant suns that remained impassive and that the size … Read more

Neptune is a dark , cold, and extremely windy planet . It is the last of the planets that we can find in our solar system. It is more than 30 times farther from the sun than Earth and it is also very similar to Uranus. It is made of a thick mass of water , ammonia, and methane on a solid center the size of the Earth. Its atmosphere is made up of hydrogen , helium, and methane, and this … Read more
Uranus is the seventh planet from the sun and was the first planet to be discovered by scientists. Although it can be seen with the naked eye, it was confused for a long time with a star, this due to the gloom that the planet has and its slow orbit . The planet is also notable for its dramatic tilt , which makes its axis point almost … Read more
A wormhole is basically a theoretical passage through space and time that could create shortcuts for long journeys through the universe . Wormholes are predicted by the theory of general relativity . But wormholes are supposed to bring with them the dangers of sudden collapse, high radiation, and dangerous contact with exotic matter about which we have no information. What is a wormhole? The wormhole is a tunnel that is responsible for connecting two different points between space and time , which in other … Read more
Edmond or Edmond Halley was an important and renowned English scientist who is best known for predicting the orbit of a comet that would later receive his name in his honor. Although he is remembered primarily as an astronomer , he also made important discoveries in the fields of geophysics, mathematics , meteorology, and physics . He was a great collaborator of Newton in the work that was carried out on … Read more
The solar system consists of the sun and everything that orbits around them, including planets, moons, asteroids, comets and meteoroids. It extends from the sun, a name that was given by the ancient Romans, and passes through the four inner planets , through the asteroid belt to the four gas giants and to the disk-shaped Kuiper belt and beyond to the cloud. spherical giant of Oort. Scientists estimate that … Read more
Pluto , the planet that was once considered the ninth and most distant planet from the sun , is now the largest known dwarf planet within the solar system. It is also one of the largest known members of the Kuiper Belt , a shadowy area beyond Neptune’s orbit believed to be populated by hundreds of thousands of rocky and icy bodies each more than 100 kilometers wide, along with 1 billion … Read more
The Large Magellanic Cloud is a nearby galaxy that was once considered an irregular- type galaxy until astronomers studied it more closely. It may have been a spiral. The Large Magellanic Cloud is only visible in the skies of Earth’s Southern Hemisphere , along with its dwarf galaxy known as the Small Magellanic Cloud . The Milky Way is constantly consuming gas that flows from the Magellanic clouds via the Magellanic Current. Eventually these two smaller galaxies … Read more
