Recent evidence suggests that Mercury was created from a larger parent body that was involved in a catastrophic collision. New computer simulations of Mercury’s formation show the fate of material blasted out into space when a large proto-planet collided with a giant asteroid 4.5 billion years ago. The simulations, which track the material over several million years, shed light on why Mercury is denser than expected and show that some of the ejected material would have found its way to the Earth and Venus.
The theory suggests that a large fraction of the debris would eventually fall back onto Mercury. The simulations showed that it would take up to 4 million years for 50% of the particles to land back on the planet and in this time many would be carried away by solar radiation. This explains why Mercury retained a much smaller proportion than expected of the material in its outer layers.
Hubble Finds "Tenth Planet" is only Slightly Larger Than Pluto
Modified from: http://www.nasa.gov/mission_pages/hubble/hst_xena_20060410.html
For the first time, NASA's Hubble Space Telescope has distinctly seen the "tenth planet," currently nicknamed "Xena," and has found that it is only slightly larger than Pluto. Because Xena is smaller than previously thought, but comparatively bright, it must be one of the most reflective objects in the solar system. The only object more reflective is Enceladus, a geologically active moon of Saturn whose surface is continuously recoated with highly reflective ice by active geysers. Xena's bright reflectivity is possibly due to fresh methane frost on its surface. The object may have had an atmosphere when it was closer to the sun, but as it moved to its current distant location, this atmosphere would have "frozen out," settling on the surface as frost. Another possibility is that Xena leaks methane gas continuously from a warmer interior. When this methane reaches the cold surface, it immediately freezes solid, covering craters and other features to make it uniformly bright to Hubble's telescopic eye.
Hubble will be used to study other recently discovered Kuiper Belt objects that are almost as large as Pluto and Xena. The Kuiper Belt is a vast ring of primordial icy comets and larger bodies encircling Neptune's orbit. Learning that the largest known Kuiper Belt object is a virtual twin to Pluto complicates the debate about whether to categorize the large icy worlds that populate the belt as “planets.” If Pluto were considered to be the minimum size for a planet, then Xena would fulfill this criterion, too. In time, the International Astronomical Union will designate the official name.
Titan’s Sandy Oceans
Modified from: http://uanews.org/cgi-bin/WebObjects/UANews.woa/3/wa/SRStoryDetails?ArticleID=12614
Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans. New radar evidence shows they are seas — but seas of sand dunes like those in the Arabian or Namibian Deserts, a University of Arizona member of the Cassini radar team and colleagues report in Science (May 5).
Radar images taken when the Cassini spacecraft flew by Titan last October show dunes 330 feet high that run parallel to each other for hundreds of miles at Titan's equator. One dune field runs more than 930 miles long, said Ralph Lorenz of UA's Lunar and Planetary Laboratory.
Ten years ago, scientists believed that Saturn's moon Titan is too far from the sun to have solar-driven surface winds powerful enough to sculpt sand dunes. They also theorized that the dark regions at Titan's equator might be liquid ethane oceans that would trap sand. But researchers have since learned that Saturn's powerful gravity creates significant tides in Titan's atmosphere, driving winds. Saturn's tidal effect on Titan is roughly 400 times greater than our Moon's tidal pull on Earth.
The researchers' model of Titan suggests tides can create surface winds that reach about one mile per hour (a half-meter per second). "Even though this is a very gentle wind, this is enough to blow grains along the ground in Titan's thick atmosphere and low gravity," Lorenz said. Titan's sand is a little coarser but less dense than typical sand on Earth or Mars. "These grains might resemble coffee grounds."
Did You Know?
The Moon has Alps
Modified from: http://www.universetoday.com/am/publish/lunar_olympics.html?922006
The lunar Alps are a range of mountains on the moon named after the Alps of Europe. They are similar to their Earthly counterparts in height, breath and spectacle. You can see the lunar Alps using a small backyard telescope. Although the two Alps look much alike, they formed in different ways. The Alps of Earth grew over a period of millions of years. Powered by plate tectonics, sections of Earth's crust pushed together, squeezing the land to produce jagged mountains. The range stretches from France through Italy all the way to Albania; the tallest peak is Mont Blanc, 15,700 feet high.
The Alps of the Moon were formed in an instant some 4 billion years ago when a huge asteroid struck and formed a big crater and the surrounding Alps. In those early days, lunar Alps were probably as jagged and rough as the Alps of Earth. But in eons that followed, meteoroids relentlessly pounded the moon, smashing rocks into dust and blunting the sharp edges of mountain peaks. Today's lunar Alps are a bit shorter (the Moon's Mont Blanc is only 11,800 feet high) and a lot smoother than their terrestrial counterparts.
