IBEX spacecraft makes first-ever images of magnetotail structures, dynamic interactions occurring in the invisible space around Earth
Martes, 14 Diciembre, 2010 Astronomía

Invisible to the naked eye, yet massive in structure around the Earth is the magnetosphere, the region of space around the planet that ebbs and flows in response to the million-mile-per-hour flow of charged particles continually blasting from the Sun. NASA's Interstellar Boundary Explorer (IBEX)...

The end of planet formation, as told by trace elements from the mantles of Earth, the Moon and Mars
Jueves, 9 Diciembre, 2010 Astronomía

New research reveals that the abundance of so-called highly siderophile, or metal-loving, elements like gold and platinum found in the mantles of Earth, the Moon and Mars were delivered by massive impactors during the final phase of planet formation over 4.5 billion years ago. The predicted sizes...

Astronomer opens new window into early universe
Jueves, 9 Diciembre, 2010 Astronomía

Thirteen billion years ago our universe was dark. There were neither stars nor galaxies; there was only hydrogen gas left over after the Big Bang. Eventually that mysterious time came to an end as the first stars ignited and their radiation transformed the nearby gas atoms into ions. This phase of...
