What are in the space?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
What is space in simple words?
In astronomy and cosmology, space is the vast 3-dimensional region that begins where the earth's atmosphere ends. Space is usually thought to begin at the lowest altitude at which satellites can maintain orbits for a reasonable time without falling into the atmosphere.
Why do they call it outer space?
Outer space, also simply called space, refers to the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace (and terrestrial locations).
What is the meaning of space research?
Space research is scientific study carried out in outer space, and by studying outer space. ... The term includes scientific payloads at any altitude from deep space to low Earth orbit, extended to include sounding rocket research in the upper atmosphere, and high-altitude balloons.
Who discovered space?
Edwin Hubble
Edwin Hubble: The man who discovered the Cosmos. Edwin Hubble changed the way we thought of the Universe forever. When scientists decided to name the Hubble Space Telescope after him, they could not have made a more appropriate choice.
How old is space?
13.8 billion years
This information helps astronomers determine the age of the universe. Age may only be a number, but when it comes to the age of the universe, it's a pretty important one. According to research, the universe is approximately 13.8 billion years old.Jun 8, 2017
What is called space?
Space, also known as outer space, is the near-vacuum between celestial bodies. It is where everything (all of the planets, stars, galaxies and other objects) is found.
How many universes are there?
The multiverse. If we define "universe" as "all there is" or "all that exists," then obviously, by definition, there can be only one universe. But if we define "universe" as "all we can ever see" (no matter how large our telescopes) or "space-time regions that expand together," then many universes may indeed exist.
