What is burning without oxygen called
Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present.
What happens to fire without oxygen
Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water.

What does fire look like in zero gravity
More of a smolder. This also means the flame burns equally in all directions forming a globe instead of the flickering flame we are used to flames in space can burn more slowly more coolly. And with
Can fire exist in space
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.

Can smoke exist in space
ago Smoke rises because it's hotter, therefore lighter, than surrounding air. It won't rise in a weightless environment. Smoke and air can exist in space, they just are not found in huge clumps because the atoms want to dispurse to reduce pressure.
What does fire look like in 0 gravity
In zero gravity, where heat does not rise, candle flames take on a uniform oval shape instead of the teardrop one seen on Earth. In space, because there is no up and down, the flame shapes look similar even when inverted. Upright, the flame is primarily next to and above the wick, where the fuel comes in.

Why is fire blue in space
Flames are blue at the base where they are hottest, and yellow above because as the hot air rises it takes some of the unburned wax with it in the form of smoke and soot. Flames on Earth are cone shaped and blue at the base and yellow at the top because heated air rises. Marianne Dyson photo, 2023.
What does the Milky Way smell like
In 2009, astronomers were able to identify a chemical called ethyl formate in a big dust cloud at the center of the Milky Way. Ethyl formate happens to be responsible for the flavor of raspberries (it also smells like rum). Space tastes like raspberries!
How cold is the space
about -455 degrees Fahrenheit
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

Is it ever hot in space
Some parts of space are hot! Gas between stars, as well as the solar wind, both seem to be what we call "empty space," yet they can be more than a thousand degrees, even millions of degrees. However, there's also what's known as the cosmic background temperature, which is minus 455 degrees Fahrenheit.

It's also very cold in space. You'll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead. Either way, your body will remain that way for a long time.

It hit the headlines a few years ago not because of its mass (which is several million times that of our sun), or even its density (up to 40 times denser than a normal molecular cloud). No, we Earthlings were fascinated because according to scientists, it smells like two of our favourite things: raspberries and rum.
