Looking at the vast universe, you have to be quite small-minded to think that Earth is the only planet out there that can sustain life. Only if you take a look at our Milky Way, you can see that is made of hundreds of billions of stars, and almost all of them have a planet. We don’t know everything that it is out there, but there have to be similar planets like ours somewhere.
So far, the scientists discovered that beyond the Milky Way, there are two other trillion galaxies. There is still so much more to find out as we’ve been asking ourselves the wrong question so far. We should change the “Is there life out there in the Universe?” question to “How will we find it?”
We are going to tell four ways to find alien life
- The first way to find extraterrestrial life is to wait for it to come to you. If aliens are out there than they should be able to visit our planet. So all you need to do is to wait.
- The second way is to look for alien signals. They could be producing signs of their existence.
- The third way is to observe. Search for biosignatures on other planets because probably not all aliens have advanced technology.
- The fourth way is to search for living organisms in our Solar System. A living organism that doesn’t belong to Earth means extraterrestrial proof.
However, we must admit that actively looking for extraterrestrial intelligence is not a very precise method to find something extraordinary. Still, if we wouldn’t try at all, then even the small chance we have would be taken from us. The good thing is that our technology advances, and it gives us more room to spread our wings in the search for aliens. Take the 30-meter class telescopes, for example.
