Let’s explore this cosmic perspective together. How big is the universe? It’s a question that stirs both wonder and humility.

And to do that, we need to zoom out beyond the solar system, beyond the Milky Way galaxy, and even beyond all the groups and clusters that comprise our neighborhood of the universe. We need to ...

One newer and equally impressive illustration shows the universe's scale in a vertical image, below. It logarithmically zooms out from infinitesimal "quantum foam" of the fabric of space (a ...

Starting with zoomed-in image showcasing the deepest view of the universe that Hubble has been able to generate, the video slowly zooms out to show the full scope of Hubble’s imaging power.

We know that the Universe is expanding, ... but if we zoom out—just like we zoom out on a smartphone with two fingers—these inhomogeneities disappear.

Each time you zoom in a depth, you're magnifying the universe 10x. Every time you zoom out, the bigger objects are one-tenth of their prior size. If you zoom from the biggest object, ...

We know that there are voids and dense regions, such as galaxies and the space between them, but if we zoom out—just like we zoom out on a smartphone with two fingers—these inhomogeneities disappear.

This Russian-nesting-doll-like distribution of matter has led them to wonder whether the universe is a fractal: a mathematical object that looks the same at any scale, whether you zoom in or out.

Now the largest 3D map of the sky ever used to measure large-scale structure shows that if you zoom out far enough, the universe is reassuringly cluster-free.

But what happens if we zoom out again. Well, we reach the end of greatness . This extremely poetic term summarizes a size above which the universe doesn’t look lumpy any more and that is at ...

Astronomers have discovered a vast tendril of hot gas linking four galaxy clusters and stretching out for 23 million light-years, 230 times the length of our galaxy. With 10 times the mass of the ...

But if you zoom out to the far reaches of our galaxy, the sun no longer looks like such a giant. In fact, it's pretty average in size. So what is the largest known star in the universe ?
