It has a fascinating history, and an exciting future as much more than the go-to metal for jewelry. Below are some interesting ways gold is used that you might not have known about.

Gold is highly conductive, which means electricity can flow through it with little resistance. That’s why it’s a popular metal for use inside smart phones, computers, tablets and more.
Gold is what powers many connections that happen in your iPhone every day. Even if yours isn’t made of gold like this one, a typical iPhone still contains an estimated 0.34g of gold, according to the U.S. Gold Bureau.
Gold in Healthcare

Gold in Space Travel
As you now know, gold is a dependable electricity conductor and reusable, reliable metal. And when you’re taking on an expensive, high-stakes project such as space travel, you want the very best elements on the periodic table on your side. That’s why gold is commonly used as a film to coat many parts of space vehicles, including satellites. According to Geology.com, “[the gold] film reflects infrared radiation and helps stabilize the temperature of the spacecraft,” to help avoid over-heating.
