What is the largest structure in space?
There are definitely no words to describe their latest find, dubbed the BOSS Great Wall, which is a supercluster of galaxies over 1 billion light years across, making it the largest structure observed in the universe so far.
What is bigger than a galaxy?

What galaxy do we live in?
The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
How many galaxies are they?
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to two trillion galaxies.
What is the smallest galaxy in the universe?

Will a black hole eventually swallow the universe?
If nothing can escape from a black hole, then won’t the whole universe eventually be swallowed up? The universe is a big place. … But collisions won’t happen indefinitely because the universe is big and because it’s expanding, and so it’s very unlikely that any sort of black hole runaway effect will occur.
