New research shows most space rocks crashing into Earth come from a single source

Raw Story  

The sight of a fireball streaking across the sky brings wonder and excitement to children and adults alike. The papers trace the origin of most meteorites to just a handful of asteroid breakup events – and possibly even individual asteroids. NASA/McREL One family of asteroids The two new studies place the sources of ordinary chondrite types into specific asteroid families …

The two small moons of Mars, Phobos and Deimos, have been puzzling scientists for decades, with their origin remaining a matter of debate. Giveaways If an impact origin did indeed occur, we would expect to find similar material on Phobos to that which is found on Mars. If Phobos formed in the same or at least similar location in the …

500 Million Years of Data Shows Meteorites Hit Earth Way Less Than What Scientists Thought

News 18  

Scientists at Lund University in Sweden tracked meteorite impacts on earth that happened over the past 500 million years. To scientists' surprise, the influx of meteorites – space rocks – has been surprisingly stable despite major collisions happening in the asteroid belt of our solar system. Using the information from chromium oxide that came from almost 10,000 meteorites, the astronomers …

Scientists believe they have identified a meteorite formed in the first million years of our solar system, making it the oldest known meteor of volcanic origin. The space rock, which began its journey some 4.5 billion years ago, has already proved an "exceptional" witness to the building blocks of the planets.

Did meteorites bring water to Earth? New evidence suggests so

India Today  

Many scientists believe that the water on Earth came from meteorites. Keeping this fact in view, the evidence of water movement in meteorites that only recently collided with Earth has taken scientists by surprise. According to a report in phys.org, a team of researchers found evidence of relatively recent water movement in meteorites that recently collided with the Earth. They …

News 18  

After analysing an ancient Martian meteorite, a team of Japanese researchers has revealed that water on the Red Planet originated some 4.4 billion years ago. But from the mineral composition of the meteorite, Mikouchi and his team revealed that it is likely there was water present much earlier, at around 4.4 billion years ago. This oxidation could have occurred if …

India TV News  

Scientists have offered new insights into the origin of diamonds in a group of stony meteorites called ureilites. These diamonds most likely formed by rapid shock transformation from graphite during one or more major impacts into the ureilite parent asteroid in the early solar system. Importantly, the ureilites that we investigated have all been highly shocked, based on the evidence …
