Meteorite violent origins
2014-08-09 05:13:23

April Flowers for redOrbit.com - Your Universe Online Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia (WA) side of Nullarbor Plain and was captured on camera. A new study, published in Geochimica and Cosmochimica Acta, indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid. The research team — comprised of Curtain University's Associate Professor Fred Jourdan, Professor Phil Bland and Dr....

redOrbit Staff & Wire Reports - Your Universe Online Since its safe landing in August 2012, NASA's Curiosity Mars rover has been busily carrying out its assigned tasks and making new discoveries. Yesterday, NASA released a new image from the intrepid little rover in which it shows an iron meteorite encountered on its travels. The meteorite, dubbed "Lebanon," is similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity....

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...

NASA Scientists Find Evidence Of Water In Martian Meteorite
2014-02-28 07:16:06

Lawrence LeBlond for redOrbit.com - Your Universe Online Evidence of water and life on Mars is a hotly debated topic that has been ongoing for decades. While most scientists agree that Mars had an abundant source of water in its ancient past, there has only been limited evidence that life may have once existed on the Red Planet. However, scientists from NASA’ Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, California have found evidence of past water...

Meteorite Reveals Martian Secrets
2013-11-21 07:06:46

April Flowers for redOrbit.com - Your Universe Online A new study has uncovered what may be the first recognized example of ancient Martian crust. The findings, published in Nature, are the work of Munir Humayun of Florida State University. His work is based on an analysis of a 4.4 billion-year-old Martian meteorite unearthed by Bedouin tribesmen in the Sahara desert. The rock, designated NWA 7533, might be the first recognized sample of ancient Martian crust and holds a wealth of...

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...

Chelyabinsk Meteorite Had Close Encounter In Space Prior To Earth Impact
2013-08-27 06:59:32

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that exploded over Russia’s Ural Mountains region earlier this year was found to have either collided with another celestial body or had a close encounter with the sun prior to reaching Earth. Researchers from the Institute of Geology and Mineralogy (IGM) in Novosibirsk, Russia announced today fragments of the Chelyabinsk meteorite – the main body that fell to the bottom of Chebarkul Lake near...

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...

Cosmochemists Help Solve 135-Year-Old Meteorite Mystery
2013-07-08 15:09:49

Lee Rannals for redOrbit.com - Your Universe Online Scientists have provided a solution to a 135-year-old mystery in cosmochemistry, saying chondrules may have formed from high-pressure collisions in the early Solar System. Chondrites are the largest class of meteorites, and scientists have wondered how numerous small, glassy spherules had become embedded within them. British mineralogist Henry Sorby first described these spherules in 1877 and suggested they may be "droplets of fiery...

Mars May Have Had Oxygen Atmosphere Four Billion Years Ago
2013-06-19 19:49:24

Lee Rannals for redOrbit.com — Your Universe Online Oxford University scientists reported in the journal Nature that Mars may have had an oxygen-rich atmosphere four billion years ago. The team examined differences between Martian meteorites and surface rocks examined by NASA's Spirit rover in the Gusev crater on Mars. Surface rocks are five times richer in nickel than the meteorites, which created some mystery for scientists as to whether the meteorites are typical volcanic...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
