Moon's mysterious 'ocean of storms' explained
Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The largest dark spot on the moon, known as the Ocean of Storms, may be a scar from a giant cosmic impact that created a magma sea more than a thousand miles wide and several hundred miles deep, researchers say. These findings could help explain why the moon's near and far sides are so very different from one another, investigators added. More

The ancient glaciers of mars —Is the red planet between ice ages?
The Daily Galaxy    Share    Share on FacebookTwitterShare on LinkedinE-mail article
"Mars is not a dead planet — it undergoes climate changes that are even more pronounced than on Earth," according to James Head, planetary geologist, Brown University. The image above was taken on June 6, 2012 by ESA's Mars Express — combined to form a natural-color view of Nereidum Montes. Undulations in crater floors are commonly seen in mid-latitude regions on Mars and are believed to be a result of glacial movement. More

Depths hold clues to dearth of xenon in air
ScienceNews    Share    Share on FacebookTwitterShare on LinkedinE-mail article
As detective stories go, the Mystery of the Missing Xenon may not have the catchiest title. But scientists in Germany say they might have cracked this long-standing enigma. The reason there's less xenon in Earth's atmosphere than expected, the researchers say, is because there was never much xenon dissolved in the planet's depths to begin with. Had there been, it would have made its way over billions of years toward the surface, there to spew into the atmosphere. More
