Universe is defined as the set of all created things (if you believe in creation) and of all things that exist.
We use words such as “universal” or “universal” to refer to a fact or idea that covers everything but often we refer to something beyond our planet, such as when an artist named “universal” or we refer the “universality” of laws, phenomena or cultural events. In these cases, but obviously we refer to the scope of our planet, we are expressing a sense of wholeness.
When discussing the astronomical universe seems more appropriate to refer to him with the Greek word “Cosmos.” Although in many dictionaries we can find exactly the same definitions for both terms, there is a difference of nuance: “Cosmos” seems limited to matter and space, while the concept of “Universe” also includes the energy and time.

Since the beginning of time, man has been curious of what lies beyond our planet; in an attempt to answer the question “are we alone?” And to find other inhabitable places we can conquer. Neil Armstrong’s moon landing truly opened new doors in the space frontier, and ever since, it has been one big leap after another. Mars has been the planet of interest for possible inhabitation and the latest efforts by NASA towards achieving this is the Curiosity Rover.
The first man on the moon; that is the enviable title Neil Alden Armstrong will forever hold. But the man had many other achievements. From the jungles of Korea to the lecture halls in the University of Cincinnati, from the barren waste of space to the boardroom of private companies, Neil achieved great deeds, deeds that would have seemed unattainable for a young boy from Wapakoneta, Ohio.
The Milky Way Galaxy is the home to our planet earth and is named so as it appears to be a band of white light which represents the mild whiteness of milk. The white light that appears to our naked eye is actually numerous stars which cannot be distinguished. People had interests in celestial objects from the very beginning. Galileo Galilei was the first person to prove the existence of various starts in the Milky Way. Later more powerful telescope was developed in the 1920′s and it was found out that many more such galaxies are present in the universe.
Scientists have grappled with the question of life on Mars with the very first scientist believing that there were other creatures living on Mars. Some of these speculations resulted from Mars’ proximity and its similarity to earth. Early scientist used their imagination and poor data from early telescopes to explain how life on Mars was possible. However, with powerful telescopes and analytical technology, scientists have been able to analyze the possibility of life form on Mars. They are now focusing on chemical bio-signatures on rocks and soil on the planet. They are also analyzing gases from Mars to evaluate whether they can sustain any form of life.
The formation of the black hole is something that people puzzle over. There is a logical and scientific reasoning which explains how the hole is formed. At the central part of the galaxy, stars are tightly packed because of gravitational pull. Because of this, collision between stars is not uncommon. Whenever 2 stars collide, they result to formation of a bigger star and this carries on. Eventually, you end up with an extremely big star and in the event it dies, an explosion follows and this creates the black hole.
Comets refer to small solar system bodies that display a visible coma and sometimes a tail when they are in close proximity to the sun. This coma and tail is caused by the impact of solar radiation and solar wind on the comet’s nucleus which is composed of loose particles of ice, small rock particles, dust and frozen gases such as methane, ammonia, carbon dioxide and carbon monoxide. Their varying orbital periods are used to categories them accordingly. Here are the two major categories of comets.
Science facts are not as immutable as some people think. Pluto’s status as our solar system’s smallest planet is the perfect example of this. Generations of children were taught in school that there were nine planets in our solar system. They were also taught that Pluto was the smallest of these and the one furthest from the sun. In fact, Pluto always seemed to have special significance because it was the furthest outpost and as such could captivate the imagination of a child like no other planet could. However, the textbooks and the science curriculum now have to be revised because on August 24, 2006 Pluto was officially declared to no longer be a planet. Instead, it is now considered to be a dwarf planet, otherwise known as a plutoid, one of many in the Kuiper belt.
