Space is a vacuum because there is extraordinarily little matter there.
Gravity is the large scale organizer of matter in the universe. It is gravity that causes material objects to attract each other, and gravity "gathers" matter together to make stars and even galaxies themselves. Because gravimetric centers -- black holes, stars, planets, comets or asteroids -- attract other matter, the matter tends to "clump" around other matter. When this matter is gaseous, and it "clumps" around bodies large enough to hold it, you have an atmosphere.
The wide volume of space between planets, or between star systems, or even between the galaxies is therefore fairly free of matter. This is as little as a handful of hydrogen atoms per cubic meter of space, compared to 1024 atoms, a trillion trillion, in a cubic meter of the air we breathe. However, space is readily and regularly traversed by moving particles, from cosmic rays (ionized atomic nuclei) to the incredibly numerous but nearly-massless particles known as neutrinos.
(Due to the energy release from stars, and the interaction of its released particles, some molecules achieve escape velocity and are "lost to space" from planets. This creates an expanded exosphere in their orbits. However, at a distance from the planets, the mass content dwindles to nearly zero.)
Use the vacuum cleaner to remove loose dirt from the carpet. OR: The vacuum cleaner works by pumping air out through the exhaust ports and reducing the air pressure within its dust chamber, thereby causing air of relatively higher (atmospheric) pressure to rush inward through the end of the vacuum cleaner's hose to achieve equilibrium, dragging dust and debris with it into the dust chamber. OR: Having extracted as much air as possible from a sealed vessel, the vessel could be considered to contain a vacuum. OR: If one were to enucleate a bubble of 'true vacuum' in normal space, the boundaries of that bubble would expand outward at near-light velocities, essentially obliterating normal space (converting it to true vacuum, wherein matter as we know it cannot exist).
No, there are trace amounts of gas and dust.
A vacuum.
Objects in space experience extreme temperatures in space becuase space is a vacuum.

A perfect vaccuum is pure space and has no particles in it
There is no true vacuum in outer space (or anywhere!). Very very roughly, if something 'froze' in outer space, the 'energy' would convert into 'frozen matter'.
The concept of space being a vacuum has been understood for centuries, but it was not until the 17th century, with the work of scientists like Galileo and Torricelli, that the idea of a true vacuum in space began to take shape. The discovery and understanding of the vacuum of space has been an ongoing process and continues to be explored through advancements in technology and scientific research.
Yes. Vibrations can travel through anything except space where there is a vacuum.
No problem ! Outer space is already a vacuum ... full of it ! I used to read that space is a better vacuum than any vacuum that can be produced in a laboratory on earth. Maybe that's not true any more. Bu the fact remains: Space is a pretty good vacuum. Open a pickle jar in outer space, wait 30 seconds, shake it around a couple times, then screw the cover back on, tight. When you get back, you'll have a jar full of the best vacuum any of your friends have ever seen. (Hard to prove, though.)
Space is a vacuum. Sound cannot travel in vacuum
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
The term for the empty space where no air exists is vacuum. A vacuum is a space devoid of matter, including air. Vacuum is commonly used in scientific research and technology applications, such as in vacuum chambers or vacuum pumps.
A true vacuum, which is difficult to create, is a space where there is nothing. AN ordinary vacuum flask has "almost" a vacuum between its mirrored glass surfaces, but no matter how long the vacuum pump is trying to remove air from inside the glass walls there will always be some left. By Willyrhus

A vacuum is composed of empty space.
