#DidYouKnow  the oldest computer is 2,000 years old!!

The Antikythera mechanism is sometimes called the world’s first computer, though it couldn’t do much that a modern computer could do. It was a hand-powered device that was used to predict the positions of stars and planets in Ancient Greece. 

#DidYouKnow  bananas are radioactive? As bananas are rich in potassium, they're technically very slightly radioactive. Humans contain around 16mg of potassium meaning we're roughly 280x more radioactive than a banana.

On the night of November 10, 1975, the Great Lakes freighter Edmund Fitzgerald sailed into a terrifying winter storm – and vanished. Her sinking remains one of the world’s greatest maritime mysteries. ☞  https://youtu.be/B7NhKr-0nm4 

#FunFact  On Mercury a day is twice as long as a year.

Technically, one Mercurian day lasts 59 Earth days, while a year lasts 88.

However, due to Mercury’s very eccentric orbit and alignment with the Sun, the length of time from sunrise to sunrise, known as a ‘solar day’, is equal to 176 Earth days — twice as long as a Mercurian year. 

Did you know that space is completely silent?

Sound waves need a medium to travel through. Since there is no atmosphere in the vacuum of space, the realm between stars will always be eerily silent. 

Did you know that the Apollo space program was named after the Greek god of light and music? 

The program was named after Apollo, the Greek god of light, music, and the Sun, by NASA manager Abe Silverstein, who later said, "I was naming the spacecraft like I'd name my baby."[4] Silverstein chose the name at home one evening, early in 1960, because he felt "Apollo riding his chariot across the Sun was appropriate to the grand scale of the proposed program". 

What is the largest planet in our solar system? 

Lurking at the bottom of the North Sea is an incredible, 1200 km long mega structure. The Langeled pipeline represents the pinnacle of underwater engineering, and you can learn all about what it took to construct it and other colossal structures over at our sister channel, All Out Engineering. 

On April 8, 2024, a total solar eclipse will cross North America, passing over Mexico, the United States, and Canada. Did you know that solar eclipses occur when the Moon gets between the Earth and the Sun, meaning we can’t see the Sun anymore? They don’t happen all the time because the Moon’s orbit is wobbly.
