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

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...

Lee Rannals for RedOrbit.com New research suggests meteorites may be the culprit behind how methane became present in the atmosphere of Mars. Using meteorites found on Earth, researchers from the University of Edinburgh, the Max Planck Institute in Germany and Utrecht University set out to find how Mars' environment started hosting methane gas. The meteorite samples used landed on Earth 40 years ago, but Dr. Andrew McLeod, of the University of Edinburgh's School of GeoSciences told...

Carbon Detected In Martian Meteorites
2012-05-25 04:02:11

Lee Rannals for RedOrbit.com Carbon, a building block for creating life, has been detected in a Martian meteorite that landed on Earth, according to a Carnegie Institution for Science study. The researchers were able to detect strong evidence that complex carbon chemistry has taken place on Mars. "These findings show that the storage of reduced carbon molecules on Mars occurred throughout the planet's history and might have been similar to processes that occurred on the ancient...

Image 1 - Dawn Mission Reveals Ateroid Vesta's Secrets
2012-05-10 13:17:00

[ Watch the Video ] Lee Rannals for RedOrbit.com NASA unleashed a new analysis of the giant asteroid Vesta on Thursday based on data taken by its Dawn spacecraft. Carol Raymond, Dawn deputy principal investigator at NASA´s Jet Propulsion Laboratory, said that Dawn's success has transformed scientists' perspective of Vesta from a fuzzy form, into a planetary body. She said that the asteroid formed within 2 million years after the first solids formed in the solar system....

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...
