Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work shows that if Earth had been slightly smaller and less massive, it would not have plate tectonics-the forces that move continents and build mountains. And without plate tectonics, life might never have gained a foothold on our wor... read full post picked by AutumnLotus 2 years ago

Sometimes the "top-10" lists can get a bit monotonous. This one has some interesting info such as the Earth has 5 natural moons, not just one. Well sort of. picked by bernardblack 1 year ago

A mineral that acts like a sponge beneath Earth's surface stores more oxygen than expected, keeping our planet from becoming dry and inhospitable like Mars. The key to the abundant oxygen storage is the mineral majorite, which exists deep below Earth's surface in the mantle. Without the oxygen stockpile, Earth would probably be a barren planet hostile to life. picked by AutumnLotus 2 years ago

Our planet faces a fiery doom inside the sun unless future generations work out how to change its orbit.

New calculations by University of Sussex astronomers predict the Earth will be burnt to a cinder then swallowed up by the sun in about 7.6 billion years. picked by AutumnLotus 2 years ago

Chondritic meteorites have a similar chemical composition to the sun and are therefore reliable witnesses as to what the solar nebula, from which the planets formed, was composed of. This can be used to deduce what the Earth consists of chemically. However, ETH Zurich researchers have now discovered that strictly speaking this fundamental geological assumption is not true. picked by AutumnLotus 2 years ago

Google Earth has some amazing and interesting images to be found. Here are a few, shown in video form (if you can ignore the cheesy music). picked by tundramonkey 3 years ago

It’s exactly forty years ago today that Neil Armstrong took man’s first step on the moon.

And to mark the historic occasion Google Earth has taken the same leap in cyberspace.

The search engine leader today launched Moon in Google Earth, an interactive 3D atlas of the moon which allows space fans to take their very own virtual steps on the surface of our closest satellite. picked by AutumnLotus 4 months ago

What would it take to jam a planet's tectonics? It seems that a huge rise in atmospheric temperatures would do the trick, causing continents to grind to a halt, mountains to stop growing and earthquakes to cease. On Earth, the motion of magma in the mantle pushes continental plates around on the surface, but if the magma became too hot and runny it would lose the grip needed to do this. picked by AutumnLotus 2 years ago

The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth is published in Nature today. Scientists hope their description of how plates collide with one sliding below the other into the rocky mantle could potentially improve their ability to assess earthquake risks. picked by AutumnLotus 2 years ago

Beetles first appeared on Earth at the same time as the earliest dinosaurs but turned out to be much better survivors, a new evolutionary study has shown. Today, there are an estimated 350,000 known species of beetle on Earth, and probably several million more yet to be discovered, say scientists. The insects account for about a quarter of all life forms on the planet. picked by AutumnLotus 2 years ago

With their high octane colours and incredible detail they look more like canvassed art than landscapes of the earth. Captured by some of NASA's most advanced satellites hundreds of miles above the earth, these unusual and striking images show our planet like never before. picked by AutumnLotus 2 years ago

The Japanese lunar orbiter "Kaguya" saw earth, moon and sun line up on April 6, 2008 and captured another "Earth-rise" and "Earth-set" HDTV video - this time when the Earth was full. picked by AutumnLotus 2 years ago

There is a growing body of evidence that suggests the Earth's magnetic field is about to disappear (at least for a while). As the magnetic poles shift position, it will have a significant effect on our terrestrial weather as well as all the gadgets we've launched into Earth orbit. picked by BrownTrout 3 years ago

A detailed analysis of the measurements of five different satellites has revealed the existence of warm cloak of plasma around Earth. This newfound feature is part of the magnetosphere, a shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind. picked by AutumnLotus 12 months ago

Desktop Earth is a wallpaper generator for Windows. It runs whenever you're logged on and updates your wallpaper with an accurate representation of the Earth as it would be seen from space at that precise moment.

This has been my wallpaper for about a year now. (Inspired to post it based on this post. picked by tundramonkey 2 years ago
