Why doesnt the sun shine in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together.

Why is it dark in space but light on Earth?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black. —What color is the sunset on other planets?

Can we see the sun from space?

NASA and other international space agencies monitor the Sun 24/7 with a fleet of spacecraft, studying everything from its atmosphere to its surface, and even peering inside the Sun using special instruments.

What does space smell like?

Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...

Why is there no sound in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Mark Thompson Reveals the Dangers of Observing the Sun! CAUTION - Not for squeamish

How cold is space?

According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

Why are there no stars in space?

Even in space, stars are relatively dim, and simply don't produce enough light to show up in photos set for bright sunlight.

Is there sound in space?

No, there isn't sound in space.

This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.

Can you fart in space?

Surprisingly, that isn't the biggest problem associated with farting in space. Though you're definitely more likely to worsen a small fire when you fart, it won't always injure or kill you. The worst part about farting in space is the lack of airflow. Let's take a step back and remember how farting on Earth works.

Is there fire in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

What is the quietest thing in the universe?

Microsoft currently holds the world record for the quietest place on Earth at -20dBA. Almost no part of the world is left untouched by sound. In fact, the only place in the universe with absolutely no sound is where there is absolutely no mass- which can only be found in a perfect vacuum.

Does the ISS stink?

The ISS is smelly, noisy, messy, and awash in shed skin cells and crumbs.

Can astronauts see the Milky Way?

To begin with, the Milky Way is easier to see. It shines a little brighter because of the lack of atmosphere, but astronauts still have to fight light pollution. Of course, this light isn't coming from planet Earth, but the station itself.

Can astronauts see planets from space?

Scott Kelly caught the moon, Earth, Venus, and Jupiter in a row from his perch on the International Space Station. American astronaut Scott Kelly, who is on a one-year mission on board the International Space Station (ISS), has become a real shutterbug.

Do bodies decay in space?

Normally, the organic component will decompose, and so the skeletons we see in museums are mostly the inorganic remnants. But in very acidic soils, which we may find on other planets, the reverse can happen and the inorganic component can disappear leaving only the soft tissues.

Does water freeze in space?

Does it freeze or boil? The surprising answer is it does both: first it boils and then it freezes! We know this because this is what used to happen when astronauts felt the call of nature while in space.

Are there any bodies in space?

Human remains are generally not scattered in space so as not to contribute to space debris. Remains are sealed until the spacecraft burns up upon re-entry into the Earth's atmosphere or they reach their extraterrestrial destinations.

How long does it take to get to the Moon?

It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon.

Can you see stars in space during the day?

Stars can be seen in the daytime sky, but this is a bit of a cheat. Stars, along with the brighter planets already mentioned, can be seen with the unaided human eye in a daytime sky (that is, when the sun is above the horizon) normally only during a total solar eclipse.

Is it dark in outer space?

Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist's illustration shows NASA's New Horizons spacecraft in the outer solar system.

Do you age in space?

In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.

Has anyone been lost in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA's space shuttle.

Do astronauts shower?

The astronauts wipe their body clean by using a wet towel, and wash their hair by using waterless shampoo. Since water does not flow in a zero-gravity environment, the astronauts cannot wash their hands under a faucet as you do on Earth. So, there are no sinks or showers inside the space shuttle.

Why do I hear when its quiet?

If you are bothered by a high-pitched sound, buzzing, or shushing in one or both ears, you may have a condition called tinnitus, which effects a majority of the population at some point in their lives.

Who is the loudest person in the world?

Irish teacher Annalisa Flanagan holds the world's loudest shouting record with 121 decibels (dB), but there was no previous singing record. The lively Bulgarian from the southern city of Plovdiv faced a series of tough requirements.
