After the first observation was made in 1995, new exoplanets are now regularly discovered by astronomers. An exoplanets is any planet that orbit around other stars, beyond of our solar system.
This is where we might find life outside or our solar system, on planet that are relatively similar to the Earth. However, they are usually very far away. The Sun's closest neighbour is Alpha Centauri, 4.37 light years away (a light year is 9.46 trillion kilometers). This means that the trip to the closest exoplanet in the universe would take at least a life's time in space.
At the frontier of science and science-fiction, Astronomy Magazine is exploring different scenarios about how we, humans, could travel that far in the universe!
