What Is Space Made Of

Astronomers have worked out that only about 5 per cent of our universe consists of baryons the particles which make up atoms which.

What is space made of. They are the constituents of space. And we don t fully understand what it is. The solar wind made up of plasma and other. Together they make up nearly all ordinary matter.

This is because there is no air in space it is a vacuum. And not only is space big we don t know what it s made of. Further space is a vacuum meaning that sound cannot carry because molecules are not close enough together to transmit sound between them. But this accounts for only a tiny slice of the universe about 5.

It s made of galaxies stars planets black holes comets asteroids and all the other cool space stuff yes there is a lot of amazing space stuff but if we add it all up it s just a very small part of the entire universe. With no air to scatter sunlight and produce a blue sky space appears as a black blanket dotted. Outer space or simply space is the expanse that exists beyond earth and between celestial bodies. Outer space begins about 100 km above the earth where the shell of air around our planet disappears.

Outer space is not completely empty it is a hard vacuum containing a low density of particles predominantly a plasma of hydrogen and helium as well as electromagnetic radiation magnetic fields neutrinos dust and cosmic rays. In space no one can hear you scream. There s a lot more out there.
