- About 8,000 miles (12,800 kilometers) below your feet — on the opposite side of Earth — lurks the unforgiving vacuum and radiation of outer space. In fact, you’re technically in space right now. Humans say “out in space” as if it’s there and we’re here, as if Earth is separate from the rest of the universe.

Outer space extends over the vast distances between astronomical objects. Being essentially empty, it allows the earliest (redder) galaxies to be viewed without obstruction, as in the Webb's First Deep Field image. Outer space (or simply space) is the expanse beyond celestial bodies and their atmospheres.
May 24, 2023 · The term outer space refers to anything beyond Earth, even things very close to home in low-Earth orbit, which begins as low as 100 miles (160 kilometers) above the planet.

For all intents and purposes, outer space is basically what lies beyond the Earth’s atmosphere. For example, the Sun, planets, stars, and galaxies - all these things are in outer space. If there’s an outer space, then it stands to reason that there must also be an inner space. This is defined as being the area between the Earth’s surface and the ed...
Most countries and organizations recognize the 100-kilometer boundary, but there are a few exceptions. For example, the US Air Force, the Federation Aviation Authority, the National Oceanic and Atmospheric Administration (NOAA), and NASA all use 50 miles (80 kilometers). (Just to complicate things further, NASA’s Mission Control uses a height of 76...
With different countries and organizations adopting different definitions of the boundary, it’s only natural to be confused about whether pilots and astronauts are in inner space, outer space, space in general or simply flying through the atmosphere. Since the FAI maintains the records for flight, and since most countries accept that the edge of sp...
