Sand Grains In Meteorite May Have Come From Milky Way-Forming Supernova
2013-04-21 07:31:06

redOrbit Staff & Wire Reports - Your Universe Online Two tiny grains of silica discovered in primitive meteorites may have originated from the ancient supernova responsible for the formation of the solar system, according to new research published in the May 1 edition of Astrophysical Journal Letters. The silica grains were discovered by scientists from Washington University in St. Louis (WUSTL) and the McDonnell Center for the Space Sciences, and was said to be...

redOrbit Staff & Wire Reports - Your Universe Online A stone originally discovered last year in Southern Morocco has been identified as a rare type of meteorite known as an achondrite, though its exact origin remains a mystery, according to experts from Washington University of St. Louis (WUSTL). The stone was one of 35 green-colored pieces discovered in early 2012. It was purchased by a dealer in the town of Erfound and then later resold to a German meteorite collector known as...

Primitive Batteries Helped Power Primordial Soup

April Flowers for redOrbit.com - Your Universe Online A research team at the University of Leeds may have solved the question of how objects from space could have kindled life on Earth. Scientists generally accept that some of the important ingredients for life came from meteorites impacting the early Earth. However, they have not been able to explain how that inanimate rock transformed into the building blocks of life. The new study, published in Geochimica et Cosmochimica Acta,...

NASA Scientists Find Striking Similarity Between Moon And Asteroids
2013-03-26 07:24:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA´s Lunar Science Institute (NLSI), along with researchers from abroad, have discovered that Earth´s own natural satellite shares a striking similarity with Vesta, and perhaps other large asteroids roaming around the Solar System. The Moffett Field, California-based NLSI found that the same population of high-speed projectiles that bombarded the Moon four billion years ago, also impacted the giant...

Space Algae Claims Scoffed By Science Community
2013-03-12 10:23:24

Brett Smith for redOrbit.com - Your Universe Online Instead of being hailed as the definitive proof of extraterrestrial life in the form of space algae, a new report from the Journal of Cosmology claiming drawing howls and catcalls from around the scientific community. The report is based on supposed meteorite fragments taken from a fireball that appeared in the evening sky over northern Sri Lanka on Dec. 29, 2012. An analysis of the fragments was performed by Chandra Wickramasinghe,...

Comets May Have Seeded Life On Earth

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Where did we come from? It is the question that has faced scientists, theologians and philosophers for millennia. And even in this age of technology, we have yet to stumble across the answer. One of the challenges is that it seems that living cells are difficult to make. Not only are they relatively complex structures, but also putting them together in such a way as to put into motion a metabolic system that can take...

Spanish Team Says Russian Meteorite Originated From Apollo Asteroid Group
2013-02-26 10:01:50

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteorite that exploded over Russia´s Ural Mountains region on Friday, February 15, has had its origins mapped by scientists. Initially, albeit wrongfully, some attributed the meteoric event to that of another celestial event that occurred on the same day: the close Earth flyby of asteroid 2012 DA14. After looking at amateur video footage, a group of researchers from Colombia were able to plot out the...

NASA Says Russian Meteorite 1000 Times Larger Than Originally Estimated
2013-02-22 14:13:51

Lawrence LeBlond for redOrbit.com - Your Universe Online Initial reports put last Friday´s (Feb 15) Chebarkul meteorite that exploded over Russia´s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons–1,000 times larger than the estimated size reported by the Russian Academy of Sciences (RAS). “My guess is that someone eyeballed the videos and made an educated guess,” said...

Interactive Map Shows Every Known Meteor Impact Since 2300 BCE
2013-02-21 05:58:57

Lawrence LeBlond for redOrbit.com - Your Universe Online With all the recent meteor events, such as last Friday´s that exploded over Russia, injuring more than a thousand people, and the possible smaller explosion over Cuba just a day later, many may be wondering if similar events have occurred in their neck of the woods anytime in the past. For those who are really interested in knowing, there is a new meteor heat map that shows every meteoric event that has occurred on land since...

Asteroid Impact In Russia: ESA Update And Assessment
2013-02-19 08:00:31

ESA The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear. ESA is carefully assessing the information as crucial input for developing the Agency´s asteroid-hunting effort. At 03:20 GMT on 15 February, a natural object entered the atmosphere and disintegrated in the skies over Chelyabinsk, Russia. Extensive video records indicate a northeast to southwest path at a shallow angle of 20° above the horizontal....

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...
