What can be found in 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

Can you fart in space?

Therefore, the fart will not be smelled by the astronaut, although they may marinate in it for a time When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell Same goes in space

What planet rains diamonds?

Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years The outer planets of our Solar System are hard to study, however Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis

How cold is space?

Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (27 kelvin)

How long is 1 hour in space?

Answer: That number times 1 hour is 00026 seconds So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 599974 seconds

Does space ever end?

No, they don’t believe there’s an end to space However, we can only see a certain volume of all that’s out there Since the universe is 138 billion years old, light from a galaxy more than 138 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists

Why is space cold?

The reason outer space is so cold is because cold is what you get when there is no source of heat nearby Objects in space cannot cool off by thermal conduction or convection, but they can cool off by radiating infrared light All objects do this, and they radiate more the hotter they get
