A star forming region in the Large Magellanic Cloud, perhaps the closest galaxy to Earth's Milky Way
A dark blue shaded diagram subdivided by horizontal lines, with the names of the five atmospheric regions arranged along the left. From bottom to top, the troposphere section shows Mount Everest and an airplane icon, the stratosphere displays a weather balloon, the mesosphere shows meteors, and the thermosphere includes an aurora and the Space Shuttle. At the top, the exosphere shows only stars.
The boundaries between the Earth's surface and outer space, at the Kármán line, 100 km (62 mi) and exosphere at 690 km (430 mi). Not to scale.

Outer space, commonly shortened to space, is the near-vacuum between celestial bodies. It is where all of the planets, stars, galaxies and other objects are found. It is the expanse that exists beyond Earth and its atmosphere.

On Earth, space begins at the Kármán line (100 km above sea level). This is where Earth's atmosphere is said to stop and outer space begins. This is not a natural boundary but is a convention used by scientists and diplomats.
