What do you know about space?

Gas, dust and other bits of matter float around “emptier” areas of the universe, while more crowded regions can host planets, stars and galaxies. No one knows exactly how big space is. This means we can “see” into space at a distance of almost 13.7 billion light-years.

How many stars are in space?

There are approximately 200 billion trillion stars in the universe. Or, to put it another way, 200 sextillion. That’s 200,000,000,000,000,000,000,000! The number is so big, it’s hard to imagine.

What are the disadvantages of going to space?

Disadvantages of Space Travel

Space travel implies significant air pollution.
Particle pollution can be a problem.
Space exploration implies high levels of waste.
Space exploration is quite costly.
Many missions may not yield any results.
Space travel can be dangerous.
Space exploration is time-consuming.

What are the dangers of space?

The major health hazards of spaceflight include higher levels of damaging radiation, altered gravity fields, long periods of isolation and confinement, a closed and potentially hostile living environment, and the stress associated with being a long distance from mother Earth.

What is one fact about space?

Interesting Facts about Space Space does not begin at a specific altitude above the Earth, but the Kármán line at 100 km is a commonly used definition. The temperature in the void of space is about −270.45 °C. Space is a hard vacuum, meaning it is a void containing very little matter. There is no sound in space because molecules are too far apart to transmit sound.

What do we find in space?

Some of the most amazing things found in space include a star made of diamond, black hole triplet and an asteroid with rings. Let’s travel into the mysterious galaxy and find out some of the most bizarre things ever discovered by scientists in the outer space.

What is the definition of outer space?

Definition of outer space : space immediately outside the earth’s atmosphere broadly : interplanetary or interstellar space : the region beyond the Earth’s atmosphere in which there are stars and planets : the region beyond earth’s atmosphere and especially beyond the solar system

What is space about?

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.
