The observable universe is just a fraction of the vast cosmos, limited by the speed of light and the age of the universe. But what lies beyond this visible horizon? In this video, we delve into five ...

However, it is possible to work out roughly how many atoms are in the observable universe — the part of the universe that we can see and study — using some cosmological assumptions and a bit ...

As vast as the Universe is, the part of it that's observable to us, both now and in the future, is still finite. With a finite number of particles and a finite amount of energy present within our ...

If you’ve ever wanted to bask in the cosmic majesty of all that exists or feel the existential horror of your own smallness, a new interactive map will show you the entire observable universe.

DOWNLOAD PDF VERSION We can only see light that has made it to our vantage point, meaning that there is a limit to how much of the universe we can see – known as the observable universe – as ...

The Cosmic Microwave Background (or “CMB”) has been a fundamental factor in every model of the Universe since it was first observed in 1965. It’s a faint, ambient radiation found everywhere ...

(The observable universe is just the universe that we can see from Earth.) The results of the latest study suggest that 90 percent of the galaxies in the observable universe are too faint or far ...

Even though it's been billions of years since the Big Bang, there's a cosmic limit to how far we can observe the objects that occupy our Universe. The Universe has been expanding all this time ...
