Martian Meteorite Age Puzzle Solved
2013-07-25 04:47:27

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Occasionally, a meteorite is found on Earth with peculiar origin: Mars. Anytime a large object such as an asteroid or comet impacts the surface of Mars, chunks of rock are ejected into outer space. Over time, some of these stones will make their way to Earth, impacting the ground as meteorites. We know that these specimens are from Mars based on their composition and other factors. So they provide an excellent laboratory for...

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...

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that blazed a trail across the morning sky in Russia this past February left a shocking impact on not just the Ural Mountains region, but the entire world. A new report published in the journal Geophysical Research Letters states the shockwave from the meteoric explosion on the morning of February 15, 2013 traveled around the globe -- not once, but twice. Scientists, led by Alexis Le Pichon of the French...

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...

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...

With more than 400 meteors per hour, it was one of the most intense meteor showers in the last decade Every 6.6 years, the comet Giacobini-Zinner circulates through the inner solar system and passes through the perihelion, the closest point to the Sun of its orbit. Then, the comet sublimates the ices and ejects a large number of particles that are distributed in filaments. The oldest of these particles have formed a swarm that the Earth passes trough every year in early October. The result...

Meteorites Brought Phosphorus Life To Earth
2013-06-05 12:53:49

Lee Rannals for redOrbit.com - Your Universe Online New research published in the Proceedings of the National Academy of Sciences has determined that meteorites that impacted Earth some 3.5 billion years ago could have helped kick start life on this planet. Scientists at the University of Washington and the University of South Florida have found that the heavy bombardment by meteorites early in our planet´s history provided the reactive phosphorus that was essential for the...

Meteorite Fragments From The Tunguska Event
2013-05-05 06:19:14

redOrbit Staff & Wire Reports - Your Universe Online A Russian scientist has reportedly found meteorite or asteroid fragments potentially linked to a mysterious explosion that took place over Siberia more than 100 years ago. The Tunguska Event, as it is called, took place in June 1908. It featured a blast that was one thousand times more powerful than the Hiroshima atomic bomb and decimated approximately 80 million trees over an 800 square mile area, but resulted in only a single...

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...
