Discovering and harnessing the power of the sun

NASA is on the hunt for new planets. On April 19, it sent a probe into space to scan the universe for cosmic bodies where life may exist. The American space exploration agency also sent a spacecraft that will be able to study the sun. This is happening at a time when solar energy is growing tremendously, and becoming more affordable. Dhananjay Khadilkhar shows us a number of everyday objects that are solar-powered. Plus, in Test 24, we discover a stuffed animal that's actually a keyboard.
