In Search Of Natural Quasicrystals
2012-08-10 04:32:11

April Flowers for redOrbit.com - Your Universe Online An expedition to far eastern Russia, a 15,000 year old meteorite, secret diaries, smugglers, gold prospectors and bears; sounds like the plot to an Indiana Jones movie, right? This is the story of two researchers looking for the origin of naturally occurring quasicrystals. Who knew science could be so exciting? Writing in Reports on Progress in Physics, Paul J. Steinhardt and Luca Bindi reveal that new, naturally occurring...

[ Watch the Video: ScienceCasts: 2012 Perseid Meteor Shower ] April Flowers for redOrbit.com - Your Universe Online Every year in August, the Perseid Meteor shower is visible to the naked eye and is a favorite for professional and amateur astronomers alike. The Perseid shower has it all. It offers a consistently high rate of meteors, it produces more bright, visible meteors than any other shower, it happens in August when many people are on vacation, and it happens at a time when...

Supernova Shock Wave And Its Role In Solar System Formation
2012-08-03 09:04:16

April Flowers for redOrbit.com - Your Universe Online It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...

Tagish Lake Meteorites Help Solve Amino Acid Mysteries
2012-07-26 14:48:28

Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...

Puzzling Science: Answering Questions About Comets And Asteroids
2012-07-26 04:57:23

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have started to answer questions about two unsolved puzzles about the building blocks of our Solar System. Two questions that have puzzled scientists about comets and asteroids are: How did icy comets obtain particles that formed at high temperatures? And, how did these refractory particles acquire rims with different compositions? Researchers from Carnegie Institution for Science have modeled the trajectories of these...

Meteorites Hold Secrets Of Earth's Formation
2012-07-23 05:32:42

redOrbit Staff & Wire Reports - Your Universe Online Scientists attempting to better understand the formation and the present-day layering of planet Earth have turned to ancient meteorites -- meteorites which they say could hold important clues to some of the Solar System's earliest chemical processes. Those meteorites are known as diogenites, and researchers from the Carnegie Institution, the Scripps Institution of Oceanography, and the University of Maryland studied nine samples...

More Evidence Of Water On Mars
2012-06-22 10:22:23

Is there water on other planets? Two Martian meteorites known to have originated from the Red Planet were recently analyzed by scientists. The amount of water they found is considerably larger than what was previously thought to have been on Mars. Knowing this not only changes what we know about the Red Planet, but also raises questions about how the water got there and if there is a probability that Mars could have supported life. The research was led by former Carnegie postdoctoral...

Weird Lunar Soil Behaviour Explained With Nanoparticles Found In Moon Glass Bubbles
2012-06-13 15:48:29

A stunning discovery by QUT soil scientist Marek Zbik of nano particles inside bubbles of glass in lunar soil could solve the mystery of why the moon's surface topsoil has many unusual properties. Dr Zbik, from Queensland University of Technology's Science and Engineering Faculty, said scientists had long observed the strange behavior of lunar soil but had not taken much notice of the nano and submicron particles found in the soil and their source was unknown. Dr Zbik took the lunar...

Intense UV radiation on the red planet releases methane from organic materials which meteorites transport onto its surface It was a sensation when scientists discovered methane in Mars´ atmosphere nine years ago. Many saw the presence of the gas as a clear indication of life on the inhospitable planet, as on Earth methane is produced predominantly by biological processes. Others assumed geological processes, such as volcanoes, to be the cause. What has been missing until now is...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
