What is the loudest sound in the universe?
The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away.
This is hailed as the loudest noise ever – and reported in..
Why is it dark in space and light on Earth?
Universe Today has another explanation: “Space is black to our perception because there are few molecules of matter that can reflect or scatter light like our atmosphere on Earth. Since light goes in a straight line it seems to be absorbed by the void and vacuum of space.
Is the sun invisible in space?
The sun is a ball of invisible, electromagnetic explosions. … As you can see from the image, some of those streams of energy blast far into space, creating solar winds and other space weather, while others rise from the sun’s surface, spin around and fall back down again in closed loops.
What does space smell 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’. Some astronauts have likened the smells of space to walnuts.
How long can a human live in space?
437 daysHow long can humans live in space? We don’t know the answer to that. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and extends that period of time. The longest contiguous amount of time a human has spent in space is 437 days.
How does the sun light up the earth?
All stars produce light (and other kinds of energy) through nuclear reactions, using the energy stored in the tiny nucleus at the center of atoms. These reactions make the star so hot that it glows — it’s like an enormous ball of fire, giving out light and heat.
Does the sun shine light in space?
Our sky is bright during the day because our atmosphere scatters sunlight in all directions. Space is dark because there is no atmosphere to scatter the sunlight. … As there is nothing else in space to shine, hence we never see the Sun’s light.
Why is it black in space?
The daytime sky is blue because light from the nearby Sun hits molecules in the Earth’s atmosphere and scatters off in all directions. … At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered.
Can you hear the sun from Earth?
Data from ESA (European Space Agency) and NASA’s Solar and Heliospheric Observatory (SOHO) has captured the dynamic movement of the Sun’s atmosphere for over 20 years. Today, we can hear the Sun’s movement — all of its waves, loops and eruptions — with our own ears.
Can you breathe in space?
Whatever you do, don’t hold your breath! The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. … Without air in your lungs, blood will stop sending oxygen to your brain.
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!
Is the sun black?
The Sun, with an effective temperature of approximately 5800 K, is an approximate black body with an emission spectrum peaked in the central, yellow-green part of the visible spectrum, but with significant power in the ultraviolet as well.
What is the loudest sound?
KrakatoaKrakatoa is believed to be the loudest sound produced on the surface of the planet — in human history, that is. It circled the Earth four times in every direction and shattered the ears of sailors 40 miles away. The Krakatoa volcano erupted with ungodly strength, sending ripples of sound heard thousands of miles away.
How many dead bodies are in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
