What is interstellar matter? What are the different parts of a black hole? What happens at the event horizon of a black hole? What happens at the center of a black hole? How fast does a black hole spin? What is the strength of the gravitational field 1.27 x 10^7 m above the Earth...
Interstellar space is not empty but filled with gas, dust and energetic particles. We explore this cosmic medium in more detail here.
When a star reaches the end of its life, it releases most of its mass back into the interstellar medium. This is done either through the formation of a planetary nebula or a supernova. In this way, stars produce and distribute heavier elements such as carbon, nitrogen, and oxygen in the...

Nebulae are mostly found within galaxies—specifically, in interstellar space. There's often at least one star at the core of a nebula, whether new or recently deceased, but sometimes a giant molecular cloud turns up starless but sporting its own subtle glow. Astronomers estimate that there are...

“Even though the interstellar gas is very dispersed, the amount of matter adds up over the vast distances between the stars. Eventually, along with enough gravitational attraction between clouds, this matter can combine and collapse to forms stars and planetary systems.” ...
