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'

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. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
Solar System, Solar System Information Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects "planets," meaning wanderers, and named them after Roman deities—Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the goddes of love and beauty, and Saturn, father of Jupiter and god of agriculture. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930). The four planets closest to the sun—Mercury, Venus, Earth, and Mars—are called the terrestrial planets because they have solid rocky surfaces. Nearly every planet—and some of the moons—has an atmosphere. Moons, Rings, and Magnetospheres From 1610 to 1977, Saturn was thought to be the only planet with rings. —Text courtesy NASA/JPL
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!
World Sunlight Map - die.net Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.
