NASA Found An Earth-Like Planet

So, a couple of days ago NASA found an Earth-like planet in what NASA and the science community calls the "Habitable Zone" by a star that is like our very own sun. What does that mean to us?

They also said they have 11 other "candidates" that could be like earth too. ALIENS!!!!!!

I find this extremely interesting, but also VERY confusing. My feeble mind can not understand the science of this or the grand scale of what this means. All I know is what I read and I found that sciencealert.com had the best and easiest to understand write up about this.

Here's What I learned

• Kepler-452b is orbiting a star called Kepler-452, located 1,400 light-years away in the Cygnus constellation of the Milky Way.
• The planet is 1.6 times bigger than Earth.
• Earlier research shows that planets of this size "have a good chance" of being rocky, just like Earth.
• Kepler-452b is orbiting a G2-type star, like our Sun.
• The planet is in the habitable zone, which means that it's far enough away from its sun that its water won't evaporate, but close enough so that it won't freeze.
• A year on Kepler-452b lasts 385 days, so the planet is only 5 percent further from its star than Earth is from the Sun.
• The planet is likely to have an atmosphere, lots of clouds, and possibly active volcanoes.
• Its parent star Kepler-452 is 6 billion years old (1.5 billion years older than our Sun).
• Kepler-452 has the same temperature, and is 20 percent brighter, and 10 percent larger in diameter than our Sun.
• Because it's orbiting a larger star, it's likely to be slightly warmer than Earth.

AND, here's an hour long Youtube video from Art of The World that says governments from around the world have been talking to aliens for a long time.
