Ice and Rock Mix Inside Saturn's Titan Mar 12, 2010
"With that information we may have a better understanding of how methane, the ephemeral working fluid of Titan's rivers, lakes and clouds, has been resupplied over geologic time. Like the history of water on Earth, this is fundamental to a deep picture of the nature of Titan through time.". The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. (Science Daily)
Big Quake Coming For U.S.? Mar 2, 2010
But if you look at it through the lens of geologic time, it does average out. " The Earth's plates are in constant motion, said Dr. McNutt, so seismic shifts of this magnitude are expected to happen on an irregular basis. The quake occurred at the interface of the Nazca and South American tectonic plates (which are converging at a rate of 80 mm a year), when the sea floor slides underneath the South American continent. Coastal Chile has experienced 13 quakes of magnitude 7.0 or greater since... (CBS News -- US)
Same Species, Polar Opposites: The Mystery of Identical Creatures Found in both Arctic and Antarctic Waters [Slide Show] Feb 23, 2010
Some scientists and naturalists, including , have hypothesized that species migrated over thousands of years when average ocean temperatures were much colder, probably at some point in geologic time between the Tertiary period and the last ice age 18,000 years ago. Darling's data, however, puts a dent in that theory. (Scientific American)
Nicknaming time Jan 15, 2010
Geologic time, which is measured in thousands and millions and billions of years, is divided into aeons, eras, periods, epochs, and ages and these are appropriately named as such. Humans, or rather their hominid ancestors, came into existence a mere three or four million years ago, the duration of their time on Earth being but a blip in geologic time.
