Scientists use Earth's 'fingerprint' to find similar exoplanets

One of the big questions we have about our vast universe revolves around the idea of ​​finding Earth-like planets (Exoplanets) beyond our solar system.

Man dreams of Earth 2.0 and aims to find this place in a universe that is not yet a known place at all. Our planet can give many clues.

Are we alone in the universe?

First and foremost, it would be nice to know if there is another planet similar to ours. What we want is to be able to find an extraterrestrial location that we might call home outside. Despite the dream, there is a need based on the survival of humanity, so we need to argue with spatial colonization.

Secondly, if a planet exists out there that supports life, there may already be life on the planet, answering the millennial question; Are we alone in the universe?

Earth has a fingerprint

As a means of better understanding potential planets that can support life beyond our Solar System, two McGill University astronomers have done something interesting. They created a “fingerprint” for the Earth that could be used to identify these types of exoplanets.

It is a glimpse of our planet’s atmosphere in infrared light, which shows the presence of key molecules in search of habitable worlds.

One in particular is of special importance, methane. Researchers expect to see methane only when a distant planet has organic sources of these compounds. In short, researchers are out there looking for a bio signature.

A group of researchers has tried to simulate Earth’s traffic spectrum, but this is the first empirical infrared traffic spectrum on Earth. This is what alien astronomers would see if they observed a transit from Earth

As suggested above, this new tool could make life easier for astronomers by trying to find more exoplanets.
