Space is among the most unexplainable and interesting topics of science. The universe is enormous in nature, and it has billions of galaxies, stars, planets, and other heavenly bodies. Despite the advancement of technology, there is still more new knowledge about the universe that scientists uncover.
The first interesting fact relating to space is that, the universe is very huge. The earth is a member of the solar system and it is a galaxy of the Milky Way. The given galaxy alone consists of hundreds of billions of stars and there are billions of other galaxies.
The light of the stars and galaxies light travels a long distance before it reaches the earth. This means that in most instances what we see as the light of the stars today was emitted by the stars several years back. This implies that when we see the night sky we are in many occasions looking on something that occurred a long time ago.
Black holes are another interesting fact of space. Black holes are areas in space where the force of gravity is very powerful such that the light cannot be emitted out of the black holes. Black holes are of interest to scientists because they investigate the nature of gravity in the extreme cases.
In our own solar system, there is unbelievable diversity between the planets. There are those planets that are very hot and those that are icy. The gas giants such as Jupiter consist primarily of gas as opposed to solid surfaces.
Space exploration has assisted scientists in coming up with a lot of information about universe. Space telescopes, satellites and space missions have enabled researchers to examine the planets, stars and galaxies more closely.
Astronauts who voyage into space are exposed to conditions that are not seen anywhere on earth like the microgravity whereby objects seem to be floating due to weaker gravitational forces. It is an environment that assists scientists to study the behaviour of human body outside the earth.
The exploration of space assists humankind to study more about the universe creation and the existence of life which is not our planet. With the ever-changing technology, new findings regarding the universe will be made in future.
