Is space really silent?
While the vast majority of space is a vacuum, and thus completely silent, there still are some areas that sound can be heard. An example of where sound in space occurs is within black holes, but unfortunately, it’s humanly impossible to hear.
Is there a purple planet?
A comparison of the Kepler planets as compared to Earth, Jupiter, and previous Kepler finds. Kepler-11e is in purple at the bottom.
Can Mars sustain human life?
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.
How fast would you die in space?
You would lose consciousness because there is no oxygen. This could occur in as little as 15 seconds.
Why Mars is red?
Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red.
Did Mars used to be like Earth?
It is thought that Mars had a more Earth-like environment early in its geological history, with a thicker atmosphere and abundant water that was lost over the course of hundreds of millions of years through atmospheric escape.
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 is the most interesting fact about space?
In the observable universe there are an estimated 2 trillion (2,000) galaxies. The International Space Station is the largest ever crewed object in space. Spacecraft have visited all the known planets in our solar system.
Is Mars Hot or cold?
Mars may look hot, but don’t let its color fool you — Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
What Colour is Venus the planet?
Why is space so cool?
The reason outer space is so cold is because cold is what you get when there is no source of heat nearby. The air picks up some of that warmth and rises, and the resulting current wicks heat away. In space, none of that can happen.
How noisy is space?
Although sound does not travel in the vacuum of space, the inside of the International Space Station (ISS) is quite noisy. There are many pumps and fans that allow people to live on the ISS. They control the station’s heat, humidity, and carbon dioxide levels.
Which planet has a life?
According to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the Universe. Nonetheless, Earth is the only place in the Universe known to harbor life.
What color is Mars?
Can you talk in space?
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.
What is the real color of sun?
