Latest Space weathering Stories
The cooperative space project Hayabasa set out to collect the very first samples from the surface of a near-earth asteroid, Itokawa. Scientists believe that the work will offer insight into the early history of our Solar System and the formation of the planets more than 4.5 billion years ago.
The traditional picture of comets as cold, icy, unchanging bodies throughout their history is being reappraised in the light of analyses of dust grains from Comet Wild2.
Japanese scientists have determined that the most common meteorites found on Earth are born from stony asteroids.
Mercury and its environment constitute a complex system that includes interactions among the interplanetary medium, the planetâ€™s magnetic field, its tenuous atmosphere (or exosphere), and its surface.
A European Space Agency-led team of astronomers has determined the rapid space weathering seen on asteroid surfaces is most likely caused by the solar wind. The study led by ESA scientist Pierre Vernazza reveals that solar wind ages and reddens asteroid surfaces much more quickly than previously thought -- in less than a million years.
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought â€” in less than a million years, the blink of an eye for an asteroid.
Asteroids and meteorites are supposed to be made of the same stuff â€“ at least that's what earth science teachers have been telling their students for decades. But until re-cently, the data didn't quite fit the story.
