The composition of Antarctic micrometeorites and other tiny but precious rocks such as those from space missions—is really hard to analyze without some sample loss. But a new technique should make it easier, cheaper and ...
To be a meteorite hunter means to search for the unutterably rare. On any given patch of land the size of Wales, an average of two olive-sized space rocks will fall in a year. Scientists and collectors are forced to go to ...
Most meteorites that have landed on Earth are fragments of planetesimals, the very earliest protoplanetary bodies in the solar system. Scientists have thought that these primordial bodies either completely melted early in ...
Southwest Research Institute scientists have increased the speed and accuracy of a laboratory-scale instrument for determining the age of planetary specimens onsite. The team is progressively miniaturizing the Chemistry, ...
The formation of our solar system was a messy affair. Most of the material that existed before its formation—material formed around other, long-dead stars—was vaporized, then recondensed into new materials. But some grains ...
Once you crush, cut or fracture a rock, there are no do-overs. It's a fact that means geoscientists have to be particularly careful about which rock samples they can sacrifice to physics experiments versus which ones should ...
A new study published in Scientific Reports reveals that asteroid impact sites in the ocean may possess a crucial link in explaining the formation of the essential molecules for life. The researchers discovered the emergence ...
A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University, has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical ...
In the past decade, there has been renewed thinking about human missions to the moon and perhaps even to Mars. Inevitably, terrestrial microorganisms on the bodies of astronauts, spaceships or equipment will come into contact ...
Mars is a long way from 221B Baker Street, but one of fiction's best-known detectives will be represented on the Red Planet after NASA's Perseverance rover touches down on Feb. 18, 2021. SHERLOC, an instrument on the end ...
