April Flowers for redOrbit.com - Your Universe Online Some meteorites found on Earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix. These "space gems," called pallasites, are only found in a tiny fraction of the total number of meteorites, but they have fascinated scientists since they were first identified as originating in outer space more than 200 years ago. A new study, published in the journal Science and led by John Tarduno at...

Scientists have uncovered evidence contained within South African rocks which shows that a weak magnetic field was present on Earth nearly 3.5 billion years ago. The evidence in question was found inside of dacite rocks from the Barberton mountain range by University of Rochester professor John Tarduno and a team of researchers. The discovery was presented during the European Geosciences Union conference in Vienna, Austria, and was also the topic of a May 4 article by BBC News science...

Scientists at the University of Rochester have discovered that the Earth's magnetic field 3.5 billion years ago was only half as strong as it is today, and that this weakness, coupled with a strong wind of energetic particles from the young Sun, likely stripped water from the early Earth's atmosphere. The findings, presented in today's issue of Science, suggest that the magnetopause"”the boundary where the Earth's magnetic field successfully deflects the Sun's incoming solar...

Fossil Find Suggests CO2 a Possible Culprit in Warm, Freshwater Arctic In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. The find strongly suggests that animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. Published today in the journal Geology, the finding also suggests that a rapid influx of...

Geophysicists at the University of Rochester announce in today's issue of Nature that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today. The findings, which are contrary to previous studies, suggest that even in its earliest stages the Earth was already well protected from the solar wind, which can strip away a planet's atmosphere and bathe its surface in lethal radiation. "The intensity of the ancient magnetic field was very similar to today's intensity,"...
