Outer Space started about 100 kilometers above the Earth, but there is still part of the Earth’s atmosphere. Outer Space is the void that exists between celestial bodies including the Earth. In space, two pieces of metal can weld together with no heat or other substances present because It’s not completely empty but it’s consists of hard vacuum containing a low density of particles which is predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, and neutrinos which it’s called Cold Welding and it was discovered in the 1940s.The baseline temperature as set by the background radiation from the Big Bang is 2.7 Kelvin (K) but in more exact term, the temperature of the emptiness of outer space is about 3 degree Kelvin. So obviously the temperature of outer space is nearly absolute zero and very cold.
There is no firm boundary where space begins. Outer space is the closet natural approximation to a perfect vacuum because it has effectively no friction, allowing stars, planets and moon to move freely along their ideal orbits. By comparison, the air we breathe contains about 10 billions light years. Stars, planets and moons retain their atmospheres by gravitational attraction. Atmospheres have no clearly delineated boundary: the density of atmospheric gas gradually decreases with distance from the object until it becomes indistinguishable from the surrounding environment.
Effect on human bodies: Sudden exposure to very low pressure, such as during a rapid decompression, could cause pulmonary barotrauma—a rupture of the lungs, due to the large pressure differential between inside and outside of the chest. Rapid decompression can rupture eardrums and sinuses, bruising and blood seep can occur in soft tissues, and shock can cause an increase in oxygen consumption that leads to hypoxia. As a consequence of rapid decompression, any oxygen dissolved in the blood would empty into the lungs to try to equalize the partial pressure gradient. Once the deoxygenated blood arrived at the brain, humans and animals will lose consciousness after a few seconds and die of hypoxia within minutes.

Apollo 13 (AS-508): Houston, we have a problem. The Apollo 13 mission was launched at 2: 13 p. m. EST, April 11, 1970 from launch complex 39 A at Kennedy Space Center. The space vehicle crew consisted of James A. Lovell, Jr. commander, John L. Swig ert, Jr. , command module pilot and Fred W. H aise, Jr. lunar module pilot. The Apollo 13 Mission was planned as a lunar landing mission but was ...
Outer Space Facts:
-Space can begins roughly 100 kilometers above the surface of Earth when the air shell surrounding the planet disappears since there is insufficient air for scattering sunlight and producing a light blue color of the sky, space looks like a dark blanket sprinkled with stars -Space is filled with numerous types of radiation, which are generally injurious to astronauts, most of the ultraviolet and the sun causes infrared radiation. -Space is not empty; the huge gaps between the planets and stars are packed with large quantities of dust and gas. -There are three orbiters that fly in space which are Endeavor, Atlantis and Discovery. -In 1981, there are two orbiters; Challenger and Columbia were lost in space because of accidents. -The matter found in space is extremely hot and this is mainly because of radiation. -Space trash that orbits at altitudes above 1,000 kilometers circles the Earth for more than a century. -Sound can’t travel through outer space because space is a vacuum, which has no molecules in it, and sound needs molecules to compress or refract.
-The Pluto is the coldest planet in solar system due to its distance from the Sun. The temperature might go down to amazing -390 degrees Fahrenheit which it’s little bit different than the ice on Earth because of the extreme temperature make it becomes harder than steel. -The light hitting the earth right now is 30 thousand years old because it spent most of this time passing through the dense atoms that make the sun and just 8 minutes to reach us once it had left the sun. The temperature at the core of the sun is 13,600,000 kelvins and all of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles. -There are more than 100 billion of galaxies in the universe and it would take about 3,000 years to count all of the stars.

-The Moon is drifting away from the earth because every year, the Moon moves 3.8 cm further away from Earth and the Earth is slowing down. Every century, the Earth’s rotation will be 2 milliseconds slower. -The most accurate definition, there are 14 black holes which are only absorb things that cross their event horizon, so they wouldn’t destroy an entire universe, it’s also possible for black holes to collide and merge, and they also absorb light. -The solar system is around 4,500 million years old and it will probably last another 5000 million years. -There are currently 166 moons in our solar system.
