NASA released this first image of Earth from the Deep Space Climate Observatory satellite today. It was snapped from 1 million miles away with an Earth Polychromatic Imaging Camera, a 4 megapixel CCD camera, and a telescope.

This is our planet as viewed from a lens on the International Space Station. It was taken during an aurora in which ions streaming from the Sun interact with gases in Earth's atmosphere. The color depends upon which gas is being excited by the ions and how much energy is being exchanged. Oxygen typically emits either a green-yellow or a red light and nitrogen typically gives off a blue light. Both oxygen and nitrogen also emit ultraviolet light which can only be detected by special cameras on satellites. The photo was tweeted by astronaut Scott Kelly on June 27 2015.

This animated video created by Hubert Heller shows Earth's new landscape if you were to pull the plug on the world's oceans. Oceans make up for 71% of the Earth's surface and contain 97% of the Earth's water. Not only would our planet be impossible to live on, it would also look disgusting! www.iflscience.com

We may not understand everything about our planet but a lot of what we do know is pretty shocking! The driest place on Earth is actually Antarctica's dry valleys- it hasn't rained there in over 2 million years!, Without Earth's unique plate tectonics carbon wouldn't be recycled and the planet would overheat!, 1 liter of saltwater contains 13 billionths of a gram of gold, The great Wall of China is not actually visible from space but the air pollution is and so is the Great Barrier Reef and We know more about our universe than we know about our oceans or earth's core and 95% of our oceans are yet to be explored! and also plenty more surprising facts!

Did you know that our days are not 24 hours long? Actually, they are 23 hours, 56 minutes, and 4 seconds long.

It's easy to lose the meaning of how large the Earth is. Here is a diagram to put the earth and its orbit in more relatable terms.

How fast are you going right now? On Earth, we are constantly rotating at around 1,000 miles per hour, even though we feel like we're standing still.
