How Far Away Is Space

There are billions of galaxies the most distant of which are so far away that the light arriving from them on earth today set out from the galaxies billions of years ago.

How far away is space. The space industry lists 62 miles. However the kármán line at an altitude of 100 km 62 mi above sea level is conventionally used as the start of outer space in space treaties and for aerospace records keeping. In december of 2012 astronomers announced a hubble space telescope discovery of seven primitive galaxies located over 13 billion light years away from us.

By the same token space is often defined as beginning at the lowest altitude at which satellites can maintain orbits for a reasonable time which is approximately 160 kilometers 100 miles above. The number of miles required to reach outer space depends on whom is asked. At or above the armstrong line fluids in the throat and lungs boil away.

Others place the marker at an astronomical 13 million miles. This survey called udf12 used hubble s wide field camera 3 to peer deeper into space in near infrared light than any previous hubble observation. The deeper we see into space the more galaxies we discover.

Nasa sets the boundary at 76 miles. Beyond our own galaxy lies a vast expanse of galaxies. This distance can change however and has varied from 205 miles 330 km to a planned maximum of 248 miles 400 km.

There is no firm boundary where space begins. More specifically exposed bodily liquids such as saliva tears and liquids in the lungs boil away. It is located at an altitude of around 19 14 km 11 89 mi.

The results are from survey of the same patch of sky known as the ultra deep field udf.
