How long is 24 hours on the moon?

The short answer is this: A day is the length of time between two noons or sunsets. That’s 24 hours on Earth, 708.7 hours (29.53 Earth days) on the Moon.

Is an hour in space 7 years on Earth?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

Is there sound in space?

Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).

How cold is space?

How much do astronauts get paid?

Has anyone been born in space?

Narrator: Scientists have studied a lot of pregnant animals in space, including salamanders, fish, and rats, but not humans. Over 60 women have traveled to space, yet none were pregnant during the trip, let alone gave birth while floating in zero gravity.

Do people age in space?

We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

How long is a day in space?

She previously worked on a Hubble Space Telescope instrument team. The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis.
