Hydrogen with some helium. However, trance amounts of other materials are seldom found in the interstellar regions of space like water, ammonia, methane, etc. And we are talking in terms of parts per trillion if not more.

What makes up the interstellar medium?
The interstellar medium is all the matter that exists between the stars in a galaxy. It mainly consists of gas (99%), with about 75% of this gas being in the form of molecular or atomic hydrogen, and about 25% in the form of helium. The other 1% is in the form of dust. The density of the interstellar medium is also very small: about 1 atom per cubic centimetre.There are two main types of interstellar mediums:Cold clouds of neutral atomic or molecular hydrogen, which are the raw materials wherein stars can be formed if it becomes gravitationally unstable and collapses.Hot ionized hydrogen near hot young stars.
What causes interstellar dust and gas to start to contract and form a protostar?
A protostar forms when gravity pulls the dust and gases in a nebula together.
What can the scientist infer about the relationship of the nebula and the pulsars life cycle?
Nebulas are interstellar clouds made of dust and gases and a pulsar is a kind of star. A pulsar is formed inside of a nebula, therefore a scientist could conclude that without a nebula a pulsar could not exist.
After bombarding a gold foil sheet with alpha particles scientist?
Scientists concluded that the atom consists of mostly empty space.
A cloud of interstellar gas is held together by?
the gravitational force
What is a diffuse mass of interstellar dust and gas?
An interstellar cloud.
What is interstellar gas cloud?
An interstellar cloud made of gas, dust, and plasma in a galaxy.
Stars form from?
Interstellar gas and dust.
What is an interstellar cloud of gas or dust?
A nebula is what it is. :)
What is a large cold cloud of gas and dust in interstellar space?
These are generically referred to as, not surprisingly; 'interstellar clouds'
What is A cloud of interstellar gas or dust?
solar nebula
What are the types of matter new stars can form from?
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
What is the name of Dark areas of gas and dust between the arms of a spiral galaxy?
Interstellar dust
What is another word for space dust?
Cosmic dust, asteroidal dust, intergalactic dust, interstellar dust, comet dust, circumplanetary dust ~ it really depends on its astronomical location.
What does gas and dust formed in our solar system produce?
It is from interstellar gas and dust that we all came. The stars, planets, asteroids, and comets all came from clouds of gas and dust. As far as OUR gas and dust NOW, nothing much is produced. Its mostly all used up in the making of us.
What does galaxy stand for?
A galaxy is a massive, gravitationally boundsystem that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter.
What is interstellar medium?
If you're referring to the space between solar systems: lots. Rocks and planetoids wander; radiation is absorbed and produced; space stretches; Von Neumann probes originating from long-extinct civilisations slowly make their way towards our solar system to convert it to rubble - you name it, it's bound to be out there somewhere.
