An iron-clad asteroid  SCIENCE DAILY · 1 month
Mineralogists have discovered a previously unknown phenomenon in soil samples from the asteroid 'Itokawa': the surface of the celestial body is covered with tiny hair-shaped iron crystals. The team provides an explanation of how these were formed, and why asteroids... more
OSIRIS-REx swoops over sample site Nightingale  PHYS.ORG · 3 weeks
NASA's first asteroid-sampling spacecraft just got its best look yet at asteroid Bennu. Yesterday, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft executed a very low pass over sample site Nightingale, taking observations from... more

Giant 'potentially hazardous' asteroid will fly safely by Earth in April  LIVE SCIENCE · 6 days
A large and "potentially hazardous" asteroid is poised to fly by Earth next month, but don't worry — it poses no threat to Earth. more
An iron-clad asteroid  PHYS.ORG · 1 month
Itokawa would normally be a fairly average near-Earth asteroid—a rocky mass measuring only a few hundred metres in diameter, which orbits the sun amid countless other celestial bodies and repeatedly crosses the orbit of the Earth. But there is one... more
OSIRIS-REx students catch unexpected glimpse of black hole  PHYS.ORG · 4 weeks
University students and researchers working on a NASA mission orbiting a near-Earth asteroid have made an unexpected detection of a phenomenon 30 thousand light years away. Last fall, the student-built Regolith X-Ray... more
Asteroid impact enriches certain elements in seawater  SCIENCE DAILY · 4 weeks
Researchers found two processes immediately after the end-Cretaceous asteroid impact that likely supplied chalcophile elements to the ocean, i.e., impact heating and acid rain. The former produced iron oxides/hydroxides and released chalcophile elements from... more
Darkness, not cold, likely responsible for dinosaur-killing extinction  PHYS.ORG · 1 week
New research finds soot from global fires ignited by an asteroid impact could have blocked sunlight long enough to drive the mass extinction that killed most life on Earth, including the dinosaurs,... more
