Our place in the cosmo

The Cosmos

The cosmos is the sum total of all matter and energy in the universe, including planets, stars, galaxies, and the contents of intergalactic space. The study of the cosmos is called cosmology.

The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.

The observable universe is the portion of the universe that can be observed from Earth. It includes all of the galaxies and other objects that can be seen with telescopes.

The night sky is full of stars, but most of them are too far away to be seen with the naked eye. The Milky Way is the galaxy that contains our Solar System.

The universe is thought to be around 14 billion years old. The Big Bang is the event that is thought to have started the universe.

Humans have always been fascinated by the cosmos. We have looked up at the stars and wondered what they are and where we came from.

In recent years, we have made great strides in our understanding of the universe. We have sent probes to other planets and even to other stars. We have built powerful telescopes that allow us to see further into the cosmos than ever before.

And yet, there is still so much that we do not know. The universe is a vast and mysterious place, and we have only just begun to scratch the surface of its secrets.
