Looking for a Backup Earth

There has been ever more exciting news of late in looking for a a hospitable, earth-like planet. Thanks to a new orbiting telescope, the news is coming faster.

Most of the best looking planets are bigger and closer to their sun that earth. that is bad news because they will probably be too hot. If it is true that earth-like planets are normally too close to a sun, maybe we should be looking near a cooler red dwarf star to find a habitable planet.
Of course, the very idea does bring this to mind.

Plus, recent progress in how we might get there.

"Visualizing" Earthquakes

Have you ever wondered what an earthquake would sound like? Well, it wouldn't sound like anything because earthquake frequencies are in the 0.01 - 100 Hz range and we humans can't hear anything below 20 Hz.

But if you were to speed up the frequency, it would sound like this. (Note: in speeding up the frequency, they speed up the recording so what you hear in a minute, took an hour in real life.)
Look at all the other things we can listen for.
