What is space?
Space is nothing – or almost nothing. It is the space that lies between the Earth and the Moon, between the planets of the Solar System, and between the stars. Space is almost empty. It does not contain any air. A piece of space the size of a house would contain a few atoms of gases and perhaps some specks of dust. Here and there meteoroids and comets move through space.

would contain・・・家のサイズの空間を取ったとしても〜しか含まないだろう
specks（複数形）・・・spec（単数形）小さな点/ わずか少量 よく否定形で用います。「部屋にはチリ一つ落ちていません」は ”There’s not a speck of dust in the room.”
meteoroid・・・いん石 meteor（流星）+ oid（の様なもの）
