What is the likelihood of Kepler452b being able to hear us, or any other exoplanets for that matter:
Humankind, after all, has been inadvertently broadcasting electromagnetic waves since the invention of radio a century ago. Those early radio transmission were weak—too weak to even make it through Earth’s ionosphere, says Seth Shostak, senior astronomer at the SETI Institute.
So how many planets are in this 70 light-year radius? Astronomers have found evidence of over 100. And how many are potentially habitable? Just thirteen.
But potentially habitable doesn’t mean there’s life—intelligent or otherwise—and actually, potentially habitable doesn’t mean, uh, very much at all. “It’s quite literally anyone’s guess what those planets are like,” says Greg Laughlin, an astronomer at the University of California, Santa Cruz.
They bring up an excellent point. Would it make sense to at least focus more on exoplanets that are somewhat in our range (if you can even call it that) vs. a planet that may appear to be similar to ours but is just so darn far away?
Feel free to comment what are your thoughts?

Baby steps.We first need to see if anyones home.call S.E.T.E. And have them aim all satellites dishes at the planet for a few months.
If they really want to get the message through all they have to do is use a laser and aim it where we want it has to be a very large laser but it’s not impossible

I think they are slightly out is cell range
What is the 70 light years range referred to in the article?
The real question should be…why would they want to?
Robert Cdizzle
This is why it bothers me when scientists say “we’ve looked and we don’t see any signs of intelligence anywhere else in the galaxy, so where is everyone?”
Well maybe all of the technology that we might be able to see is young enough that it hadn’t had time to reach us. This could mean it’s less than 1000 years old or it’s less than 100,000 years old or older depending on where in the galaxy they may happen to be.
