An ocean's color is determined by the...

In 1984, NASA initiated the Gravity Probe B (GP-B) program to test two unverified predictions of Albert Einstein's theory of general relativity—hypotheses about the ways space, time, light, and gravity relate to each other. To test these predictions, the Space Agency and researchers...

A solar cell is a semiconductor device that converts photons, or light, into electricity. The most widely used solar cells today are made from wafers of mono- or poly-crystalline silicon.

In order to better understand our solar system and the ways it supports life, scientists and researchers at NASA study the planets. Of course, one of the planets on which NASA focuses most of its research is the Blue Planet, Earth, since this is the only one currently known to support life; and it is...

Soil, water, and light. According to prevailing dogma, these are the three main ingredients for growing and maintaining healthy plants. But what if you take soil completely out of the equation and limit the presence of water significantly? Can you still nurture plants in such an...
