Vitamin B3 May Have Been Made In Space, Delivered To Earth By Meteorites

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...

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...

Martian Meteorite Has Building Block Of Life
2013-06-12 11:41:42

Rebekah Eliason for redOrbit.com - Your Universe Online A Martian meteorite discovered in Antarctica was found to contain some of the early building blocks of life. The Antarctic Search for Meteorites (ANSMET) team discovered that this meteorite was clearly of Martian origin during its 2009-2010 field season. Contamination from the earth was ruled out and the meteorite was sent to the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) for further study. The findings from...

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...

By Daniel Stolte, University of Arizona The discovery of minerals requiring liquid water for their formation challenges the paradigm of comets as "dirty snowballs" frozen in time. For the first time, scientists have found convincing evidence for the presence of liquid water in a comet, shattering the current paradigm that comets never get warm enough to melt the ice that makes up the bulk of their material. "Current thinking suggests that it is impossible to form liquid water inside of a...

Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. The stratospheric dust includes minute grains that likely formed inside stars that lived and died long before the birth of our sun, as well as material from molecular clouds in interstellar space. This "ultra-primitive" material likely wafted into the atmosphere after the Earth passed through the...

The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team of colleagues. Heck and his colleagues examined 22 interstellar grains from the Murchison meteorite for their analysis. Dying sun-like stars flung the Murchison grains into space more than 4.5 billion years ago, before the birth of the solar system. Scientists know...

Scientists are puzzled by the composition of a mysterious space rock discovered in Antarctica. Matthieu Gounelle from the Laboratory of Mineralogy and Cosmochemistry at the French Natural History Museum, is leading the research on the strange micrometeorite known as MM04. Astrochemists are puzzled by the composition of MM04. The tiny rock "“ only 150 microns across "“ is made up of a "unique" chemical composition, Gounelle said. MM04 was a basaltic achondritic micrometeorite, Dr...

To see the world in a grain of sand has a resonant poetry when astronomers try to understand the rain of dust and meteors that blanket the Earth daily. It turns out that doing astronomy with a microscope has its benefits, particularly when the extraterrestrial samples arrive at our doorstep. Astrobiology Magazine -- William Blake's vision: "To see a world in a grain of sand" is being realised by a group of researchers at the University of Manchester. Their work, which involves analysing...

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
