twin

My goal is to find a true Earth twin, and to search for signs of life on it.

We want to find a true Earth twin with continents oceans and sunlight and a thin atmosphere with oxygen, a place where we humans could potentially live.

Now making their late night debut performing the song "Haunt Me," please welcome back Twin Temple.

But to be honest with you, if something happened to my twin brother – even though I do this job – I don't know if I’d be able to take it.

If they hadn’t been raised on different continents by completely different families, you could almost bet they were twins.
