This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. '
All living organisms require energy to grow, move and survive. In space, there's not enough breathable oxygen to allow these processes to happen. Plus, in a low-pressure environment like space, even if someone did have air in their lungs, it's likely the air would expand quickly and their lungs would burst.
Did you know that there are storms always occurring in space? Not rain or snow, but winds and magnetic waves that move through space! This is known as space weather.
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.
Other astronauts have described it in similar yet varying ways: "burning metal," "a distinct odor of ozone, an acrid smell," "walnuts and brake pads," "gunpowder" and even "burnt almond cookie." Much like all wine connoisseurs smell something a bit different in the bottle, astronaut reports differ slightly in their " ...
On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.
Oxygen does exist in space, though the Goddard Space Flight Center notes that it wasn't formed during the Big Bang. Instead, it arrived due to nuclear fusion reactions in the newly formed stars. As the stars consumed hydrogen and helium, they created carbon and oxygen.
The Short Answer:
Earth's gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.
The air that fills the box is being pushed by air pressure into the empty space. Vacuums never “suck” air. What they do is present an empty space and then air pressure forces the air into the vacuum. Air pressure is not uniform throughout the atmosphere.
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. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever.
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.
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.
The short answer is the astronauts and cosmonauts (that means a Russian astronaut) bring oxygen from Earth, and they make oxygen by running electricity through water (this is called electrolysis).
Because of Earth's gaseous gifts to space, our planet — or, to be specific, the atmosphere — is shrinking, according to Guillaume Gronoff, a senior research scientist who studies atmospheric escape at NASA's Langley Research Center in Virginia. However, we're not shrinking by much, he said.
PLASMA PROCESSES Mars's thick early atmosphere was likely lost to space, and the Sun is a potential culprit. When high-energy solar photons strike the upper Martian atmosphere they can ionize gas molecules, causing the atmosphere to erode over time.
Far outside our solar system and out past the distant reaches 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 (2.7 kelvin). Are you shivering yet?
Among the stunning variety of worlds in our solar system, only Earth is known to host life.
The atmosphere of the planet Uranus contains mostly hydrogen, helium, and methane. Interestingly, the methane in the atmosphere is what gives Uranus its distinctive blue color. Since Uranus contains effectively zero free oxygen, the hydrogen and methane in the atmosphere does not burn or explode.
Problem 3 – Which planet has the atmosphere with the greatest percentage of Oxygen? Answer: From the table we see that Mercury has the greatest percentage of oxygen in its atmosphere.
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
