If alien life exists on exoplanets, how would we know?
If alien life exists on exoplanets, how would we know? Seager has been described as an "astronomical Indiana Jones" The Genius Behind - Sara Seager Astrophysicist Sara Seager believes she has a way to reveal the biological secrets of a ‘second Earth’ – watch the video above to see how. It’s not like we can zoom in to look at the surface of an alien planet “We think there are upwards of hundreds of billions of planets in our galaxy alone,” says astrophysicist Sara Seager. Seager, however, believes she has a way to spot biological signatures on exoplanets – and it involves a giant flower-shaped spacecraft capable of blocking out the light of an entire star. Seager has said in the past she only has one goal in life, besides raising her children: to find a second Earth Exoplanets need to live in the Goldilocks zone – not too hot, not too cold, but just right for life, says Seager To find life, we will need to launch an enormous 'starshade', says Seager The video above is part of a series called The Genius Behind: The most amazing and sometimes little known technological and scientific breakthroughs of modern times, and the innovative minds behind them.
