@cleoabram: We can find planets far outside our solar system and search for signs of life without ever leaving Earth. You might think we would need to fly there or send a spacecraft to take a sample – nope! We found water vapor on a planet several light years away with this one incredible technique. Here’s how they do it and exactly what we’re looking for on distant planets that would hint at alien life. Follow along to learn more!
