TWO MOONS???


"Oneureun dugaeui dari, dugae, dugaeui dari

Oneureun dugaeui, dugaeui dal, dal, dari tteuneun bam
Two moons, two moons, two moon two moon two moons
 tteona oneul bame
 tteona oneul bame
 two moons, two moons, two moon two moon two moons"

I'm singing Two Moons by EXO!!!
EXO~~~kyeaaa!!!!!!!!

By the Way,not the song that i wanna i talk about..Its the PHENOMENON that i wanna talk about TODAY!lATELY,I FOUND THIS ARTICLE AND FOUND IT VERY VERY INTERESTING!!!

Earth Had Two Moons That Crashed to Form One, Study Suggests


This computer illustration depicts a collision between Earth’s moon and a companion moon that is 750 miles wide and about 4 percent of the lunar mass. This late, slow accretion could explain the moon's farside highlands, scientists say.
A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests.
The second moon around Earth would have been about 750 miles (1,200 kilometers) wide and could have formed from the same collision between the planet and a Mars-sized object that scientists suspect helped create the moon we see in the sky today, astronomers said.
The gravitational tug of war between the Earth and moon slowed the rate at which it whirls, such that it now always shows just one side to Earth. The far side of the moon remained a mystery for centuries until 1959, when the Soviet Luna 3 spacecraft first snapped photos of it. (The far side is sometimes erroneously called the dark side, even though it has days and nights just like the near side.) [Video: The 2 Sides of the Moon (And What's On Them)]





Facts about the EARTH II


Elegant Earth


Alien worlds may be all the rage, with their mystique and promise, but the orb we call home, planet Earth, has all the makings for a jaw-dropping blockbuster movie: from the drama of explosive volcanoes, past meteor crashes and catastrophic collisions between rocky plates to the seeming fantasy of the ocean's deep abysses swirling with odd life and tales of the coldest, hottest, deepest, highest and all-out extreme spots. So try to stay grounded as you take a journey through some amazing facts about Earth.
Third Rock
Our home, Earth, is the third planet from the sun and the only world known to support an atmosphere with free oxygen, oceans of liquid water on the surface and — the big one — life.

Squashed Sphere
It's not a perfect sphere. As Earth spins, gravity points toward the center of our planet (assuming for explanation's sake that Earth is a perfect sphere), and a centrifugal force pushes outward. But since this gravity-opposing force acts perpendicular to the axis of Earth, and Earth's axis is tilted, centrifugal force at the equator is not exactly opposed to gravity. This imbalance adds up at the equator, where gravity pushes extra masses of water and earth into a bulge, or "spare tire" around our planet. 

She's Got a Waistline
Mother Earth has a generous waistline: At the equator, the circumference of the globe is 24,901 miles (40,075 kilometers).

Hot Spot
The fiery award for Earth's hottest spot goes to El Azizia, Libya, where temperature records from weather stations reveal it hit 136 degrees Fahrenheit (57.8 degrees Celsius) on Setp. 13, 1922, according to NASA Earth Observatory. There have likely been hotter locations beyond the network of weather stations. (The image was created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite.


Pole Flip-Flops


In fact over the past 20 million years, our planet has settled into a pattern of a pole reversal about every 200,000 to 300,000 years; as of 2012, however, it has been more than twice that long since the last reversal. These reversals aren't split-second flips, and instead occur over hundreds or thousands of years. During this lengthy stint, the magnetic poles start to wander away from the region around the spin poles (the axis around which our planet spins), and eventually end up switched around, according to Cornell University astronomers.


Facts about the EARTH!!

Well, Geography is ,

Geography (from Greek γεωγραφίαgeographia, lit. "earth description") is the science that studies the lands, the features, the inhabitants, and the phenomena of the Earth. A literal translation would be "to describe or write about the Earth". The first person to use the word "geography" was Eratosthenes (276-194 BC).[3] Four historical traditions in geographical research are the spatial analysis of the natural and the human phenomena (geography as the study of distribution), the area studies (places and regions), the study of the man-land relationship, and the research in the earth sciences. Nonetheless, modern geography is an all-encompassing discipline that foremost seeks to understand the Earth and all of its human and natural complexities - not merely where objects are, but how they have changed and come to be. Geography has been called "the world discipline" and "the bridge between the human and the physical science". Geography is divided into two main branches: human geography and physical geography.
