Scientists reveal new vision of Earth 4 billion years ago

The Hadean and Eoarchean epochs were the real hell on Earth. For millions of years, our planet was heavily bombarded by millions of asteroids with "existing oceans repeatedly boiled away into steam atmospheres"until its crust finally solidified. These two new visualizations will help you comprehend this violence. » 7/30/14 5:22pm 7/30/14 5:22pm

The Earth looks flat in this photo taken from space

Believe it or not, some idiots think that Earth doesn't rotate and others still think that Earth is flat. I'm sure the latter group would love this picture just taken by our space Captain America—astronaut Reid Wiseman. The angles on those two coasts converging makes Earth's spheroidal surface look strangely flat. » 6/23/14 9:10pm 6/23/14 9:10pm

NASA makes zoomable Earth using 36,422 selfies from all continents

Not even Ellen DeGeneres can beat this one: NASA asked people to take selfies on Earth Day and humans from Antarctica to Zimbabwe submitted more than 50,000 photos. Of those NASA selected 36,422 photos to create this fully zoomable 3.2 gigapixel image of Earth's Eastern and Western hemispheres. » 5/22/14 12:56pm 5/22/14 12:56pm

Simulation of Saturn passing by Earth on a collision course to the Sun

The always cool Yeti Dynamics has released another brilliant scientific simulation: What would Earth's sky look like if Saturn went off its orbit to race into the inner solar system on its way to the Sun and our planet was on its path? I just love these impossible but visually arresting scenarios. » 5/05/14 1:43am 5/05/14 1:43am

This is how the moon would look in the sky if it were a disco ball

Vsauce's Michael Stevens answers a great question with the help of Yeti Dynamics: What if the moon was a disco ball? The answer is sad: The mirrors' specular surface would make the moon almost invisible. However, things really get groovy if you put the disco moon at the same distance as the International Space Station. » 4/04/14 3:49pm 4/04/14 3:49pm

This is the oldest fragment of Earth ever found

You're looking at the oldest fragment of Earth ever found: a zircon 4.375 billion years old, something that has deep implications in our understanding of the planet's formation. While some scientists said other samples weren't genuine, new research just published in the journal Nature Geoscience proves that this is » 2/24/14 1:00am 2/24/14 1:00am

This space image of the Sahara feels more painting than photograph

I'm loving these photos at an oblique angle from the International Space Station. Most Earth photos from space look so flat, but these have such a three-dimensional quality. This one in particular, showing clouds over the Western Sahara Desert also feels painted with delicate brushstrokes, thanks to the lighting and… » 1/27/14 11:07am 1/27/14 11:07am
