Above: Banded Iron Formation (BIF) from Hamersley Basin, Australia. This rock was deposited in an ocean 2.5 billion years ago and may record evidence for biologic activity at that time.

The Origins Lab at the 2nd France-Chicago Science Festival, 2012

For the second edition of the France-Chicago Science Festival, the Origins Lab, in association with the Field Museum, once again introduced high and middle school students to various topics in the Earth Sciences, including the origin of Earth and Earth's earliest history. The display involved exhibit of meteorites, hands-on activities on how to recognize them and differentiate them from terrestrial rocks as well as introduction to geological time-scales through posters (Download poster here 2.3MB, and explanation here 168KB).

Three Publications Cover our Research on Mars

News of our lab's work on the development of Mars has been sprouting up around the web. The study, published in the May 26 issue of Nature and authored by lab leader Nicolas Dauphas and former Origins Lab researcher Ali Pourmand, found that Mars developed in as little as two to four million years after the birth of the Solar System. In other words, Mars is "just a baby." Check out what Astrobiology Magazine, RSC, and BBC News have to say about it!

 

"Supernova Shrapnel Found in Meteorite"

Our work in the Astrophysical Journal has been featured by Science Daily: "Scientists have identified the microscopic shrapnel of a nearby star that exploded just before or during the birth of the solar system 4.5 billion years ago." Read the rest on their website.

 

"Scientist Refines Cosmic Clock To Determine Age Of Milky Way"

We're developing better ways to measure the age of the galaxy: "The University of Chicago's Nicolas Dauphas has estimated the age of the Milky Way at approximately 14.5 billion years by combining telescopic observations with laboratory analysis of meteorites..." Read the rest.

 

"Study Resolves Doubt About Origin of Earth's Oldest Rocks, Possibility of Finding Traces of Ancient Life"

Rocks from Greenland indeed give us earliest evidence about life on Earth. Origins Lab leader Nicolas Dauphas is quoted: "My results show unambiguously that the rocks are sediments deposited at the bottom of an ocean... This is an important result. It puts the search for life on the early Earth on firm foundations." Read what else Nicolas has to say.
