New Study: Iron Rain may Explain Earth-Moon Differences

March 3, 2015 |

Not much is known about Earth’s “inner space” —its core — although scientists agree on one thing. Much of the core consists of iron. But just how much iron is there remains the subject of debate. Now, new research show that the asteroids that slammed into Earth and the moon more than 4 billion years ago were vaporised into a mist of iron. Read More

Life on Earth may have Flourished Even Before 3.2 Billion Years Ago

February 19, 2015 |

The ancient Earth was a hostile environment marked by unpredictable climate and oxygen-deprived air over 3 billion years ago. Until this week, scientists believed that life forms came into existence, and started using Earth’s nitrogen, around 2 billion years ago. But the new research from the University of Washington changes all these previous theories. Read More

Earth’s Inner Core has an Inner Core of its Own?

February 10, 2015 |

While there’s no prehistoric land hidden at the centre of our planet, as author Jules Verne imagined, the Earth’s core may not at all be like what scientists have led us to believe. Geologists have discovered that the Earth’s inner core – previously thought to be a solid lump of iron – may in fact have its own even smaller core within it. Read More

Really Amazing Video of Lightning Seen from Space

February 1, 2015 |

Do you ever asked yourself just how ‘Lightning Seen from Space’? Dramatic photos from NASA show lightning in the eye of Cyclone Bansi on January 12. The rare images were taken by Italian astronaut Samantha Cristoforetti aboard the International Space Station (ISS), who managed to capture the lighting at the exact second it hit the eye of the cyclone.

How much Space Debris is Really in Orbit around Earth?

January 28, 2015 |

More than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth. They all travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft. Read More

What would Earth Look Like with a Different Sun?

January 25, 2015 |

It’s hard to imagine what life would look like if we were rotating around some star other than the sun. So the Russian Federal Space Agency imagined for us. And it looks awesome. The video above puts different stars at the center of our solar system, envisioning Earth in a very different light. Five different lights, actually. Read More

New Study Finds: Ocean Wildlife May End Soon

January 17, 2015 |

Most people are well aware by now that the human impact on Earth’s ecosystems is rarely positive. But what about the oceans, those vast, unyielding expanses of biodiversity? A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.

What If the Moon were Replaced with Some of Our Planets?

January 8, 2015 |

What would happen if the moon were replaced by various planets in the sky? One YouTube user has taken a look at this hypothetical scenario – and the results are rather impressive. Read More

New Rosetta Data Suggest Earth’s Water Didn’t Come From Comets

December 11, 2014 |

Take a virtual trip around the Solar System and you’ll come to one conclusion pretty quickly: Earth is odd. One of the most significant oddities about our pale blue dot is the vast quantity of liquid water. Astronomers and other scientists have proposed various arguments for how Earth ended up with huge, stable liquid oceans — and now, thanks to research from the Rosetta probe, we’ve got evidence that one prominent theory may not be correct.

Earth is Being Protected by Invisible Space Shield From ‘Killer Electrons’

November 30, 2014 |

It’s a well-known fact that Earth’s ozone layer protects us from a great deal of the Sun’s ultra-violet radiation. Were it not for this protective barrier around our planet, chances are our surface would be similar to the rugged and lifeless landscape we observe on Mars. Read More

New Technique could Help to Produce more Reliable Photonic Chips

November 18, 2014 |

Researchers from the University of Southampton have developed a new technique to help produce more reliable and robust next generation photonic chips. Read More

Visions of the World 1000 Years From Now

November 17, 2014 |

“What will the world will be like in 1,000 years” seems like an absurd question to even ask, yet curious people do wonder, and certain people like Ray Kurzweil spend all their time working to find the answers. Here are the top 5 reasons to look ahead. Read More
