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....

Early Sun's Violent Beginnings May Have Unlocked The Mystery Of Milky Way Meteorites

Gerard LeBlond for redOrbit.com - Your Universe Online Observations of a Sun-like star through the Herschel Space Observatory may have unlocked the mystery of meteorites in our own galaxy, according to European Space Agency (ESA) astronomers. Astronomers are studying young stars in faraway areas of the galaxy, discovering they have a violent beginning, much as our own sun did 4.5 billion years ago. Herschel is surveying the chemical composition of stars being born and a team of...

moon formation collision theory

redOrbit Staff & Wire Reports - Your Universe Online The Moon was most likely formed by a collision between the Earth and a planet-sized object that took place roughly 4.5 billion years ago, a team of German scientists report in research published Friday by the journal Science. According to the Associated Press (AP), the study authors took an in-depth look at moon rocks that had been gathered during the Apollo 11, 12 and 16 missions. They discovered that moon rocks have a different...

Chelyabinsk Meteor Collided With Asteroid Before Hitting Earth

Lawrence LeBlond for redOrbit.com - Your Universe Online A wealth of research has come following the Chelyabinsk meteor that exploded over Russia’s Ural Mountains on February 15, 2013. The latest study, which comes from scientists at the University of Tohoku in Japan, claims that the meteor collided with an asteroid before heading on its collision course with Earth. Analysis of a mineral called jadeite found embedded in fragments recovered after the explosion show that the parent body...

Alberta Crater May Have Been An Ancient Meteorite Impact Site
2014-05-08 10:46:42

Gerard LeBlond for redorbit.com - Your Universe Online Evidence from an ancient ring-like structure discovered in southern Alberta, Canada, suggests it was formed by a meteorite strike. The meteorite was large enough to form a five-mile-wide crater and if a strike of that magnitude occurred today, the resulting explosion would obliterate Calgary. A research team led by Doug Schmitt, a Canada Research Chair in Rock Physics from the University of Alberta, studied the site discovered by a...

Sentinel Telescope May Help Save Us From Earth-Killing Asteroids

Lawrence LeBlond for redOrbit.com - Your Universe Online Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood. But in the modern world, are the impacts portrayed in movies like Deep Impact and Armageddon only the stuff of science fiction? The answer is likely no. Scientists continue to warn us of the dangers that lurk in the skies above us and in the past dozen or so years, no less than 26...

Fireball Flying Over Northern Russian City Caught On Vehicle Dash Cam
2014-04-22 06:59:42

Lawrence LeBlond for redOrbit.com - Your Universe Online A suspected meteorite explosion has been recorded by citizens of the northern Russian city of Murmansk over the weekend. The fireball left a noticeable bright blue trail as it sped across the night sky at about 2:14 am (local time) on Saturday, before ending in explosion, according to multiple witnesses. There were no reports of damage during this weekend’s encounter, yet the fireball did raise some eyebrows due to its eerily...

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...

Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...

Data will help scientists read Curiosity Mars rover samples for signs of life, says UMD coauthor of study published today in Nature. (PRWEB) April 16, 2014 Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year...

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...
