'Mysterious Object' May Be First 'Extinct' Meteorite. Scientists Find Strong Evidence That the Earth Was Hit Head-On by a Mars-Sized Planet. The early solar system was, for lack of a better term, a chaotic hellscape.

Scientists Find Strong Evidence That the Earth Was Hit Head-On by a Mars-Sized Planet

Everything we see today, from Mercury on out to the inner Oort Cloud, was a product of a series of collisions that accumulated into moons, asteroids, and planets. And perhaps one of the most violent blows came when a planet roughly the size of Mars smashed into a fledging planet called Earth. At the end of the cataclysmic event, two bodies were left standing: Earth itself, and a fragmentary, molten piece of the two planets that coalesced into the Moon.

The bus-sized meteor that slammed into Russia in February, causing a massive shock-wave and injuring hundreds of people, sent a plume of dust into the stratosphere that circled the globe in just four days and lingered for months, NASA says.

The Feb. 15 meteor at Chelyabinsk near Russia's southern border with Kazakhstan measured 60 feet across and weighed 12,000 tons. It detonated 15 miles above the city. According to Space.com: This Pulsing Earth : Krulwich Wonders... It's breathing, he thought.

"All of a sudden I see a thing with a heartbeat. " John Nelson is a designer, well known for tracing complex weather patterns or cultural information on maps, so considering what he usually does, this was easy. NASA's Visible Earth team publishes pictures of our planet every month of the year, so John thought, why not stitch them together, and see what the seasons look like from outer space? So he stitched, and then looked. "I was surprised," he writes on his UX.Blog. After working a few hours on getting the cartographic mumbo jumbo out of the way (projection, coloration, atmospheric haze, and stuff), I first got to see the frames flicker in front of me, and I just stared at it as it looped over and over again.

These images are gripping. Mysterious Dancing Lights In Afghanistan : Krulwich Wonders... Sgt.

Cassini captures photo of Earth and Moon as seen from Saturn. If the midweek hump has you in a contemplative spirits, this stunning image of Earth as pictured by the Cassini spacecraft from Saturn, 898 million miles (1.44 billion kilometers) away, may offer a little context.

Cassini captures photo of Earth and Moon as seen from Saturn

The Earth and the Moon appear to be seemingly insignificant specks from the perspective of the spacecraft from its orbit around the gas giant, the second biggest planet in the Solar System. But as it turns out, Cassini is actually talking us up. View all The image, taken on Friday, represents the first time that Cassini–Huygens (to give the spacecraft its full name) has captured the Earth and Moon as distinguishable from each other using its highest res wide-angle camera. Both the Earth and the moon actually appear larger than they should due to the long exposure used to capture as much light as possible. Black Country crop circles prove phenomenon is no hoax, claims Australian expert. AN Aussie historian believes he has buried forever the ‘cereal’ lie that crop circles are the work of hoaxers – by unearthing Black Country images of them dating back to 1945 and beyond.

Black Country crop circles prove phenomenon is no hoax, claims Australian expert

It’s ‘barley’ believable, but Greg Jefferys has also uncovered evidence of the phenomenon in scientific documents dating back to 1880. The boffin, from Hobart, Tasmania, says his findings prove there’s more to the mysterious circles than hoaxers playing silly tricks. “This discovery proves that claims by various artists to be the sole creators of crop circles are themselves a hoax,” he says. “It just goes to show that the circles remain unexplained. “I hope this discovery will stimulate renewed interest in crop circles by serious scientific researchers who have been fooled by the hoax claims.”

Greg, aged 59, who cut his teeth locating shipwrecks, used Google Earth’s new 1945 overlay – images of places taken 68 years ago – to make the breakthrough.

Dubbed “Black Marble,” the high-resolution images were released December 5 at a meeting of the American Geophysical Union. BLACK MARBLE Lights from human activity ring the otherwise dark Atlantic Ocean in this new image, part of a collection showing Earth at night more clearly than ever before.
