Intergalactic space is as close as you can get to an absolute vacuum. There’s very little dust and debris, and scientists have calculated that there’s probably only one hydrogen atom per cubic meter. The density of material is higher near galaxies, and lower in the midpoint between galaxie...

Space has celestial bodies like asteroids, moons, planets, stars, black holes, galaxies, etc. Everything that has a mass also has gravity. The higher the mass the higher the gravity. In fact, the amount of gravity of an object is proportional to its mass and distance between it and anoth...
Outer space refers to the areas between planets, solar systems, galaxies, galaxy clusters and galaxy superclusters. There is littlematterin outer space. It is a hard vacuum, without any air. This also makes it extremely cold. There are some stray particles andradiation, though. Ironically, eve...
[金星原创] What is the universe?The universe contains everything that exists including the Earth, planets, stars, space, and galaxies. This includes all matter, energy, and even time.How big is the universe?No one knows for sure just how big the universe is. It could be infinitely large...
From the light that is visible in our telescopes, we have charted galaxies reaching almost as far back as the Big Bang, which is thought to have started our universe about 13.8 billion years ago. This means we can "see" into space at a distance of almost 13.8 billion light-years. But ...
In contrast, the universe is a much broader term that includes everything that exists: all matter, energy, galaxies, stars, and even the empty spaces in between them, extending to the furthest reaches of the cosmic horizon. 7 While space is considered part of the universe, serving as the ...
In the large empty areas between stars and planets, there are no molecules (分子) to vibrate (振动). So there is no sound there. Space can be beautiful. The planets, stars, galaxies and other things make many beautiful and colourful shapes. We can see them by telescope. Space can be ...
in space.Some areas had a lot of galaxies, and other areas had just a few.Uh, another way of putting this is to say that galaxies are clustered.They're not spread evenly throughout the universe.So we have stars grouped together in galaxies, and galaxies grouped together in clusters. OK...
