What Will Happen When The Earth's Magnetic Field Switches

The Earth’s magnetic field protects life on Earth, shielding it from damaging radiation and moderating our climate. So the idea that it could completely flip around, or collapse altogether, should cause us to worry, right? Well, yes and no.


4 Ways Tiny Microbes Changed Life On Earth Forever

This is the microbes’ world — we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don’t underestimate the power of tiny, tiny microbes populating the Earth trillions of times over.


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.


The Fossilised Machines Humans Will Leave Behind

In the debut issue of a new journal called The Anthropocene Review, University of Leicester geologist Jan Zalasiewicz leads a team of five writers in discussing the gradual fossilisation of human artifacts, including industrial machines, everyday objects, and even whole cities. They refer to these as “technofossils,” and they’re destined to form a whole new layer of the earth’s surface.


NASA Astronomer Finds First Earth-Sized Planet In Habitable Zone

The search for a new Earth outside the solar system seems to be nearing its end. NASA’s Ames Research Center astronomer Thomas Barclay has found a planet nearly the size of Earth in the habitable zone of a star in the Milky Way.


The Earth Was Almost Fried Back In 2012

A massive solar storm in July 2012 was more intense than thought — and it blasted right through the Earth’s orbit. Luckily for us, we were on the other side of the sun, thus missing the chaos completely. But if that storm had hit this beautiful little blue marble in space? “The solar bursts would have enveloped Earth in magnetic fireworks matching the largest magnetic storm ever reported on Earth, the so-called Carrington event of 1859,” Science Daily reports.


Marvel At These 10 Amazing Geological Formations

Chocolate hills, fairy chimneys, stone forests — this isn’t a children’s story, but a selection of the most impressive geological features in the world. From Australia’s Wave Rock to Queen’s Head in Taiwan, these incredible structures were all crafted by Mother Nature, whether it was churning volcanic activity or grinding tectonic plates.


The Pale Blue And Red Dot Shows Where Plant Life Is Thriving

Forget the Pale Blue Dot, let’s throw some red in there too. This false colour image shows plant growth across the planet in red where usually you’d expect some green.


Cool Visualisation Shows Liquid Water On Earth Vs Jupiter's Moon Europa

I knew that NASA wants to send a submarine to explore the oceans of Jupiter’s moon Europa, but I never realised that Europa has more liquid water than Earth even while it’s roughly the size of our Moon. This graphic shows the shocking difference clearly, but there’s more.


Why The Same Side Of The Moon Always Faces The Earth

One moon “day” is approximately 29.5 Earth days. This rotation coincides with its orbit around the Earth so that we only see about 59 per cent of the surface of the moon from Earth. When the moon first formed, its rotational speed and orbit were very different than they are now. Over time, the Earth’s gravitational field gradually slowed the moon’s rotation until the orbital period and the rotational speed stabilised, making one side of the moon always face the Earth.
