New technology discovers primitive organic matter in 4.5 billion year old meteorites Meteorites contain fragments of asteroids brought about by collisions within the asteroid belt. These meteorites have not been exposed ...
During their entry to Earth, meteoroids and asteroids can deposit energy, causing great concerns to astrophysicists. Recent discoveries of the massive Aletai irons in Northwest China constitute the longest-known strewn field, ...
Strangelets, and specifically nuclearites, their heavy species, are very dense, compact and potentially fast objects made of large and roughly equal numbers of up, down and strange quarks, which may inhabit the universe. ...
Multimodal microscopy can combine complementary nanoscale imaging techniques to extract comprehensive information on the chemical, structural and functional aspects of heterogenous samples. X-ray microscopy can achieve high-resolution ...
When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...
(Phys.org)—If you had to predict the probability of a catastrophic meteor striking the Earth, you would likely want the most accurate models on which to base your predictions. But a new paper shows that, because the most ...
(PhysOrg.com) -- When a meteor impacts a planet or a moon, it always stops at a relatively shallow depth, even when impacting at high speeds. Until now, researchers have assumed that all objects impacting a granular medium ...
The Space Age is leaving fingerprints on one of the most remote parts of the planet—the stratosphere—which has potential implications for climate, the ozone layer and the continued habitability of Earth.
At the center the Earth is a solid metal ball, a kind of "planet within a planet," whose existence makes life on the surface possible, at least as we know it.
An international team of researchers studying material from the asteroid Ryugu returned to Earth by the Hayabusa-2 Japanese space probe has found evidence that the asteroid formed in an outer part of the solar system, near ...
