Space (or Outer Space) officially begins at the Kármán Line, an invisible boundary 100 km (62 miles) above the Earth. It takes its name from Hungarian engineer Theodore von Kármán (1881-1963) who calculated that the air is too thin to support aeronautical flight beyond that altitude.
Outer space is only an hour away, if you could drive your car straight into the sky at 60 MPH (96.5 km per hour).
Above altitudes of approximately 160 km (100 mi) the sky is completely black.
The term "space" was first used to mean the region beyond Earth's sky in John Milton's Paradise Lost in 1667.
The earliest known use of the phrase "outward space" was in the poem Maiden Of Moscow by Lady Emmeline Wortley in 1842. "Outer space" was first used as an astronomical term by Alexander von Humboldt in 1845. The expression was later popularized in the early 20th century writings of H. G. Wells.
The first film with outer space in its title was It Came From Outer Space in 1953.
The United Nations passed its Outer Space Treaty on January 27, 1967, precluding any country from claiming sovereignty over anywhere in space. The treaty also bans the nations that signed it from putting weapons of mass destruction into space. The treaty entered into force on October 10, 1967.

World Space Week is an annual holiday observed from October 4 to 10 in over 95 nations throughout the world. It marks the launch on October 4, 1957 of the first man-made satellite, Sputnik 1, into orbit by the Soviet Union and the signing of the Outer Space Treaty on October 10, 1967. It is officially defined as "an international celebration of science and technology, and their contribution to the betterment of the human condition".
The temperature of most of outer space is -454 ºF. (–270.45C), or 2.7 degrees above absolute zero. However, in sunlight near Earth, temperatures can swing to a boiling 250 ºF. That's why astronauts wear reflective white spacesuits.
When astronauts return from space walks and remove their helmets, they are welcomed back with a strange smell Astronauts have described it, like "seared steak." And also: "hot metal." And also: "welding fumes."
There is no sound in space. Space means no atmosphere which means there is nothing for the sound waves to travel though.
It used to be thought that Outer Space is a vacuum. It is now estimated that Space contains a few hydrogen atoms per cubic meter.
The picture below is part of the Hubble Ultra-Deep Field image showing a typical section of space containing galaxies interspersed by deep vacuum. Given the finite speed of light, this view covers the last 13 billion years of the history of outer space.
There is a supermassive void in space called the Boötes void and if the Milky Way had been in the center of the void, we wouldn't have known there were other galaxies until the 1960s. The void is 0.27% the width of the entire observable universe.
A human being can survive exposed to space for about 15 seconds with no permanent damage. They would probably asphyxiate from the lack of breathable air and suffer from ebullism, in which a reduction in pressure would cause your saliva to boil, and your blood vessels to burst. There is one movie that got this right - Kubrick's 2001: A Space Odyssey.
Here is a list of songs about space.
