From the perspective of an Earthling, outer space is a zone that occurs about 100 kilometers (60 miles) above the planet, where there is no appreciable air to breathe or to scatter light. In that area, blue gives way to black because oxygen molecules are not in enough abundance to make the sky blue.Further, space is a vacuum, meaning that sound cannot carry because molecules are not close enough together to transmit sound between them. That's not to say that space is empty, however. Gas, dust and other bits of matter float around "emptier" areas of the universe, while more crowded regions can host planets, stars and galaxies.No one knows exactly how big space is. The difficulty arises because of what we can see in our detectors. We measure long distances in space in "light-years," representing the distance it takes for light to travel in a year (roughly 5.8 trillion miles, or 9.3 trillion kilometers).Activity on the Sun’s surface creates a type of weather called space weather. The Sun is really far away—about 93 million miles (150 million kilometers)—from Earth. However, space weather can affect Earth and the rest of the solar system.Space Race –The groundwork for the billionaire space race and NewSpace was arguably laid by Peter Diamandis, an American entrepreneur. In the 1980s, he founded an American national student space society, the Students for the Exploration and Development of Space (SEDS). Later, Jeff Bezos became a chapter president of SEDS. In the 1990s, Diamandis, disappointed with the state of space development, decided to spur it on and spark the suborbital space tourism market, by initiating a prize, the X Prize. This led to Paul Allen becoming involved in the competition, creating the Scaled Composites Tier One platform of SpaceShipOne and White Knight One which won the Ansari X-Prize in the 2000s. The technology of the winning entrant was then licensed by Richard Branson's Virgin Group as a basis to found Virgin Galactic. The base techniques of Tier One also form the basis for Stratolaunch Systems of Vulcan Aerospace. The billionaire space race shows the aims of billionaires extend beyond just fulfilling government contracts, with their own gilding of the space age, in extending capabilities and their own luster. Three billionaires who are leading this space race/ space tourism are Elon Musk with SpaceX, Jeff Bezos with blue Origin and Richard Branson with Virgin Galactic.Sources- Various, Britannica, Wikipedia..
