Can astronauts hear the rocket in space?
No. The sound produced by the engines is mostly in shockwaves in the exhaust plume, and those leave the spacecraft just fine in a vacuum.Can astronauts hear in spaceship?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.Can astronauts hear each other in the space station?
Sound is a mechanical wave and requires a material medium for propagation. There is nothing in space. There is no atmosphere. Even if the astronauts are floating in the atmosphere next to each other they can't hear each other.Can you hear an explosion in space?
In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically 'explode'.Can you hear someone scream in space?
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.Mysterious 'Music' Heard in Outer Space
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).What does space smell like?
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.What is the loudest sound in the universe?
The 1883 Krakatoa volcano eruption was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can't hear them.Could a nuke go off in space?
If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. Second, thermal radiation, as usually defined, also disappears.Would a grenade explode in space?
Grenades generally explode on the ground, creating a mushroom like blast that we usually see in movies. In space, it would become nearly a spherical blast, but the format will vary significantly with the grenade shape. Chemical propellant, so it would go off, also depends on its fuse system it uses.Is it dead silent in space?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.Why Cannot we talk in space?
The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.How do astronauts sleep?
The astronauts sleep in small sleeping compartments by using sleeping bags. They strap their bodies loosely so that their bodies will not float around. In the zero-gravity world, there are no "ups" or "downs". The astronauts can sleep anywhere facing any direction.Can you play music in space?
As there is air on a spacecraft, musical instruments should still work. However, it might not work if you try to play outside of a shuttle or space station. On a violin or guitar, the strings would vibrate without producing a sound.Can you hear noise on the Moon?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.Does Earth make 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.
Is Hiroshima still radioactive?
Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.How long would it take for the Earth to recover from nuclear war?
Recovery would probably take about 3-10 years, but the Academy's study notes that long term global changes cannot be completely ruled out. The reduced ozone concentrations would have a number of consequences outside the areas in which the detonations occurred.How many nukes does it take to destroy the Earth?
The declassified study from the scientists at the Los Alamos laboratory, published in 1947 had first shed light on the question that how many nuclear bombs it would take to destroy the world. According to the study, it would take about ten to a hundred 'super nukes' to end humanity, a publication reported.How loud is a black hole?
Converting the energy of 1,100 decibels to mass yields 1.113x1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila!Does the sun make noise in space?
The Sun is a roiling ball of plasma and gas and if you could survive the temperatures within it, it would probably sound like a gigantic pot of boiling jam being hit by a nuclear bomb! The sound doesn't reach us across the vacuum of space, but there are slower waves that we can see moving on the surface.What is a sound of sun?
The Sun does indeed generate sound, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.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.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.Why is space dark?
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.
