"The production of the silicon wafers that are used in the chip manufacturing process requires extraordinary levels of purity."

One big goal of science is to find an inhabited, Earth-like planet. But if we find an Earth-like world, will we even recognize it?

Military satellite research brought us GPS. Astronomers influenced medical imaging tech. What would be invented after we discover alien life? Professor Sara Seager explains the consequences of such a groundbreaking discovery.

Many reactions emit energy, often in large amounts, but cosmic efficiency is another metric altogether. Here's how to maximize your output.

The benefits of mathematical literacy reach far beyond the realm of numbers and equations.

The unanswered questions about sex, love, and pregnancy in space could shape the future of humanity more than we think.

The Universe is expanding, the expansion is accelerating, and some galaxies even recede faster-than-light. Can we see a change in real time?
