Bill Steigerwald, NASA's Goddard Space Flight Center Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts. "It is always difficult to put a value on the connection between meteorites and the origin of life; for...

New Techniques Tease Out Building Blocks Of Life In Meteorites
2014-02-04 06:24:52

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...

Sutter's Mill Meteorite Considered Scientific Gold
2013-09-11 05:44:09

April Flowers for redOrbit.com - Your Universe Online Researchers from Arizona State University (ASU) have made an important discovery about the possible inventory of molecules available to the early Earth. Sandra Pizzarello, a research professor in ASU's Department of Chemistry and Biochemistry, led the team in examining the Sutter's Mill meteorite - which exploded in a blazing fireball over California last year - to find that it contains organic molecules not previously found in any...

Early Solar System Garnet-like Mineral Named After Ian Hutcheon
2013-08-13 15:20:30

Lawrence Livermore National Laboratory A recently discovered mineral appears to be clear but may have a tinge of light blue. No matter its color, you won't be able to make earrings from it. For one, you can't see the material with the naked eye. Hutcheonite, recently named after Lawrence Livermore meteorite researcher Ian Hutcheon, can be seen only with high powered scanning electron microscopes. Known also by its chemical makeup, Ca3Ti2SiAl2O12, hutcheonite was discovered in a...

Sutter's Mill Meteorite Under The Microscope
2012-12-21 05:32:02

Lee Rannals for redOrbit.com - Your Universe Online A meteorite study has led scientists to believe that asteroid surfaces may be more complex than previously thought. Scientists from around the world have come together to work on a meteor analysis of the Sutter's Mill meteorite that fell down to Earth in April 2012. The scientists reported in the journal Science that this particular meteor is an unusual example from a rare group known as carbonaceous chondrites. Samples from this...

In Search Of Natural Quasicrystals

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...

Lee Rannals for redOrbit.com - Your Universe Online New research suggests that meteorites, and their parent asteroids, are most-likely the sources of Earth's water. Scientists have believed that comets, or a primitive meteorite called carbonaceous chondrites, were the sources of earth Earth's volatile elements, including hydrogen, nitrogen, and carbon. Having an understanding of where these volatiles came from is crucial when determining the source of water and life on the planet....

Newly Discovered Mineral Provides Clues To Evolution Of Solar System
2012-06-27 09:42:28

Lawrence LeBlond for redOrbit.com A previously unknown mineral has been found in a meteorite that fell to Earth in 1969, according to a Caltech geologist who has been studying the meteoric sample since 2007, and who has also found eight other new minerals in the sample. The Allende meteorite was among thousands of meteorites that lay scattered about the state of Chihuahua, in Mexico, after a meteor exploded over the region in 1969. More than 40 years later, the meteorite is providing...

A new isotopic analysis of meteorites that have been in storage on Earth for quite some time points to a very reasonable scientific conclusion that Mars once had sea beds that were warm, wet and rich in organic chemicals. Dr. John Brandenburg, a former scientist at the Florida Space Institute-University of Central Florida, Kennedy Space Center, says that the meteorites he analyzed, come from rocks in the southern hemisphere of part of Mars.  The rocks are 4.5 Billion years old, the same...

The earliest rocks in our solar system were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience The earliest rocks in our Solar System were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience. The work, by researchers from Imperial College London and other international institutions, provides the first geological evidence to support...

Meteorite -- A meteorite is a relatively small extraterrestrial material body that reaches the Earth's surface. While in space these bodies are called meteoroids. Upon entering the atmosphere air drag and friction will cause the body to heat up, emitting light, thus forming a meteor, fireball, or shooting star. Most meteors disintegrate in the air, making impact events (Earth impacts) on the surface of Earth uncommon. About 500 baseball sized rocks a year reach the surface. Large...
