Discovery of 1,800-year-old 'Rosetta Stone' for tropical ice cores
Two annually dated ice cores drawn from the tropical Peruvian Andes reveal Earth's tropical climate history in unprecedented detail—year by year, for nearly 1,800 years.
Grains of sand from ancient supernova found in meteorites
(Phys.org) —It's a bit like learning the secrets of the family that lived in your house in the 1800s by examining dust particles they left behind in cracks in the floorboards.
New research eclipses existing theories on the Moon formation
The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as "Theia." Over the past decades scientists have simulated this process and ...
Mars rover Curiosity targets unusual rock enroute to first destination
