Moon's interior water casts doubt on formation theory 26 May 2011Last updated at 19:01 By Jason Palmer Science and technology reporter, BBC News The study looked at pockets of volcanic material locked in glass An analysis of sediments brought back by the Apollo 17 mission has shown that the Moon's interior holds far more water than previously thought. The analysis, reported in Science, has looked at pockets of volcanic material locked within tiny glass beads. It found 100 times more water in the beads than has been measured before, and suggests that the Moon once held a Caribbean Sea-sized volume of water. The find also casts doubt on aspects of theories of how the Moon first formed. A series of studies in recent years has only served to increase the amount of water thought to be on the Moon. The predominant theory holds that much of the water seen on the lunar surface arrived via impacts by icy comets or watery meteorites. They wrote in a Nature paper that the samples contained about 10 times more water than they expected. 'Not consistent'

Afghan Scouts learn to 'be prepared!' By Adrienne Mong, NBC News Correspondent KABUL – In the United States, being a Boy Scout or a Girl Scout is just one of many diversions offered to kids. But here in Afghanistan, it's not simply a diversion – it's a matter of survival. The worldwide scout motto, "Be Prepared" ("Tayar Osay" in Pashto) takes on a larger, more urgent, importance in this war-torn country. We could see that clearly at the Alluhodin Orphanage in Kabul on a recent afternoon. A round of first aid demonstrations was being led by Zainab Ramin, a 16-year-old who came to the orphanage four years ago from Mazar-i-Sharif after her parents were killed in the war with the Taliban. At first, she and her younger sister went to live with their only relative, an uncle. "We go to school and study our lessons. Zainab especially enjoys being an Afghan Scout and admires its values. She realized it was her son's Boy Scout background that had taught him to be so well-prepared. A scout legacy Getting 'life skills'

The Solar system Source: [accessed 2009] You may have wondered if there was a tenth planet out there. Wonder no longer; the astronomers have changed the meaning of the word planet so such pondering is no longer valid! Source: KBO's [accessed 2009] Our solar system is now filled with interesting things and I hope to go into many of them here. Our solar system of course has a structure just like our galaxy has. The wikipedia has more details on the solar systems structure , but here is a list of the basic structure of our solar system: Sun Inner Solar System Inner Planets: Mercury; Venus, Earth and Mars. Asteroid Belt: contains Vesta and Hygieia--may be classed as dwarf planets Ceres which is classified as a dwarf planet. Outer Solar System Outer Planets: Neptune, Uranus, Saturn, Jupiter Comets Trans-Neptune Region Kuiper Belt : has debris similar to the asteroid belt and also contains: Haumea (egg shaped, with two moons) and Makemake.

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física.

7 Horrible Ways The Universe Can Destroy Us Without Warning The universe hates you. Let's get that out of the way right now. The universe loathes your guts and is infuriated by the way you dress, and the stupid way you talk sends it into a murderous rage. It's just one bad morning and an empty coffee canister away from driving to your house and shanking you in the neck. What we tend to call shooting stars are really just meteoroids burning in the Earth's atmosphere. GettyThe stars want you dead. How They Will Get Us: But it's probably OK: We've only found like 16 of these things zipping about. GettyIf you ever meet a woman who's impressed with your bat'leth skills, it's probably time to start worrying. But the thing with the universe is that it's kind of a largish place. Getty"How about Earth? And we're not exaggerating that "hypervelocity" part, either -- an average HV star moves at a staggering 1.6 million kilometers an hour. GettyThe whole universe is basically a grab bag filled with medical waste. Via NASAOh yeah, great. Wait, what? Yeppers!
