What is the significance of carbonaceous chondrites

These bodies were far more numerous [4 billion] years ago, but suffered a gravitational destabilisation during Jupiter and Saturn's migration to its current location. Those that did not end being swallowed by Jupiter and Saturn were rejected towards the terrestrial planets and to other regions of the Solar System, transporting water and organic material inside them," explains the CSIC researcher.

The study also points at the direct implications for the origin of water in Earth. And they did it transporting in their fine matrices water and other volatile elements in form of hydrated minerals," says Trigo. The results from the carbonaceous chondrites' analysis at a micro- and nanoscale that are published in this new study reveal the importance of the sample-return missions, that can bring to Earth rocks less altered by collisions than the meteorites that land on the terrestrial surface.

ScienceDaily, 14 February The ir conclusion was that it had traveled on a somewhat elongated orbit that extended out to the outer asteroid belt. The suggestion has been made that a possible parent body is the main-belt asteroid Irmintraud , which is a dark object spectroscopically similar to the material composition of the Tagish Lake meteorite and other carbonaceous chondrites.

Alan Hale was born in Tachikawa, Japan as the son of a U. Air Force officer but moved with his family later soon after to Alamogordo, New Mexico, where he spent his childhood years. Hale entered the Navy and graduated from the U. While at JPL he was involved with several spacecraft projects, most notably the Voyager 2 encounter with the planet Uranus.

His thesis paper has become one of the seminal papers in early exoplanet research, with over citations to date. He has developed and taught astronomy-related educational activities at the university level. He is primarily known for his work with comets, which has included his discovery of Comet Hale-Bopp in In recent years he has worked to increase scientific collaboration between the U. He has two sons, Zachary and Tyler, both of whom have graduated from college.

On clear nights he can often be found making observations of the latest comets or other astronomical phenomena.
