How Close Are We To Finding Aliens?

Do you believe in aliens? I do, and here’s why. I think it would be irrational to say that in a universe with billions of planets and suns much like our own, that there does not exist some form of extraterrestrial life.

In this article, we will uncover the possibility of alien life in our universe. We will start by identifying the most-likely planet outside our solar system, or exoplanet, that may contain life. Then we will dive into the latest cosmological research from the world’s leading astrophysicists that hint at the very possibility. Finally, we will build up the best rational argument as to why aliens probably do exist.

The first step in our quest to locate life is to find planets similar to earth. Our galaxy alone houses an estimated 40 billion earth-like planets. The phrase “earth-like” implies that the planet is roughly of equal distance from its sun, the same size, and rocky. The most earth-like planet we know of so far is called Kepler-452b, NASA officials say. Its host star is very similar to our sun, and the planet orbits in the habitable zone. Kepler-452b exists 1,400 light-years from Earth in the constellation Cygnus.

Now let’s take a closer look at this exoplanet, Kepler-452b. Exactly how “earth-like” is it? We will draw some comparisons. At 1.6 times the size of Earth, Kepler-452b is a rocky planet. It orbits at a similar distance (430 parsecs) from its parent star. Finally, it has a corresponding 385-day year. While we can prove these overlapping characteristics between earth and Kepler-452b, we must still remain skeptical and search for less tantalizing discoveries.

Unfortunately, our current technology will not allow us to travel to this exoplanet. As we are not an interstellar species (yet). So we make do with what we have in the 21st century. Sticking to our guns, we still beam out radio frequencies in hopes of reaching an advanced alien race. Researchers at the SETI Institute have listened for extraterrestrial radio signals from Kepler-452b, but have had no luck so far. Despite the lack of signaling communication, we still remain optimistic and will continue to explore this exoplanet’s possibility to harbor alien life.

With all that said, nobody can say for sure there is life on Kepler-452b. Bear in mind that the research is still in its early stages and more discoveries emerge almost daily. A series of breakthroughs must take place in space exploration before we can even consider the possibility of initiating contact with our cosmological neighbors.

What we can do is point ourselves in the right direction and focus on a few realistic possibilities. Only then can we begin working towards sending probes to distant places that may find extraterrestrial life. Perhaps the largest scientific feat is underway, and this is only the beginning…
