We think of outer space as a vacuum, containing nothing. This is not entirely true. There is matter - mostly gasses - throughout space. It's very thin - but it is, barely, detectable.
We measure hard vacuum in terms of atoms per cubic meter.
Most of the gas floating around in space is hydrogen; but then, most of the material in the universe is hydrogen. Scientists believe that almost all of the matter that came out of the Big Bang was hydrogen, with just a little helium (and tiny traces of lithium) in the mix. Early stars fused the hydrogen into helium, and then into carbon, silicon, oxygen, iron and all of the other "heavy" elements. When those early stars exploded in supernovas, those explosions blew vast quantities of those other elements back into space.
When the later stellar nebulae formed, the hydrogen came to the center to form the star, but the heavier elements sometimes coalesced to form planets. We're not entirely certain of the precise details of how this process works yet, but the broad outlines are clear enough.
What else can I help you with?
Can gas exist in space?
Yes, gas can exist in space. The interstellar medium, which fills the vast majority of space, consists of gas and dust particles. Stars are also made up of gases like hydrogen and helium. However, since space is a vacuum, these gas particles are very spread out compared to the atmosphere on Earth.
How did the gas get in to space to make the sun?
The gas was in space from the beginning of the Universe - the Big Bang. Eventually, gravity pulled parts of this gas together, to make the Sun, as well as other stars.
How is oxegyn provided in space?
A gas tank
What is the hink pink for a distant ball of burning gas in space?
A synonym for distant would be far and a burning ball of gas in space is a star.
What is a gigantic cloud of gas and dust in space?
what is a astronomer
What is gas in the disc space?
what is gas in the disc space?
Why can gas fill any space?
gas ca fill any space cause gas is very powerful and strong
Where can i find confined space gas detectors?
There is currently a sale on confined space gas detectors at pksafety. They have several models to choose from: http://www.pksafety.com/confined-space-gas-detectors.html
What is a homophone for hot ball of burning gas in space?
A homophone for "hot ball of burning gas in space" is "son."
Why do gas fills it containers?
Gas diffuses in space.
How does the total volume of gas particles compare to the volume of the space between the gas?
The amount of space that gas particles can take up is the size of the container, but the amount between them also is determined by the amount of space the gas takes up.
What is term used to indicate the space a weight of gas will occupy?
The term used to indicate the space a weight of gas will occupy is called "volume." It refers to the amount of physical space that a gas occupies.
What is the space that a gas takes up called?
The space that a gas takes up is called its volume.
Is there air or gas in out of space?
no
What us the term fir a cloud of dust and gas in space?
A cloud of dust and gas in space is known as a Nebula.
Why doesnt the gas on a gas giant planet escape into space?
For the same reason that our atmosphere on Earth does not escape into space - gravity.
Can gas exist in space?
Yes, gas can exist in space. The interstellar medium, which fills the vast majority of space, consists of gas and dust particles. Stars are also made up of gases like hydrogen and helium. However, since space is a vacuum, these gas particles are very spread out compared to the atmosphere on Earth.
