Built to look for gravitational waves, the ripples in the fabric of space itself that were predicted by Einstein in 1915, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is the most ambitious project ever funded by the National Science Foundation. We talk to two Caltech researchers to learn about how LIGO came to be.

If microbial life exists elsewhere in the solar system, wouldn't we like to actually see it on the move? Bioengineers are already testing a new scope—in extreme environments a bit closer to home—that could capture the 3D videos to make that possible.
