Robert A. Pritzker Center for Meteoritics and Polar Studies

Robert A. Pritzker Center for Meteoritics and Polar Studies The Robert A. Pritzker Center for Meteoritics and Polar Studies at the Field Museum's Department of Geology in Chicago houses the largest meteorite collection at a private institution.
(2)

Pritzker Center curates one of the largest meteorite collection. In addition, the Center maintains a large cosmochemistry and sample preparation laboratory. The center was estalished through a generous endowment by the Chicago-based Tawani Foundation and is part of the three-institution Chicago Center for Cosmochemistry (C^3) together with Argonne National Laboratory and the University of Chicago.

Mission: Meteorite loans from the collection can be requested for research loans by qualified scientists for high-quality research and exhibits. We maintain a strong research program in meteoritics and cosmochemistry. We are also strongly engaged in educational programs from elementary school to advanced university courses and public outreach activities. A strong interest in studies in the polar regions is also part of the Center's mission.

Back in 1972, NASA sent their last team of astronauts to the Moon in the Apollo 17 mission. These astronauts brought some of the Moon back to Earth so scientists could continue to study lunar soil in their labs. Since we haven’t returned to the Moon in almost 50 years, every lunar sample is precio...

We're excited that our paper on new neon exposure ages of presolar grains is now published!

Dating of interstellar dust directly with astronomical methods is not possible. Neither is dating based on the decay of long-lived radioactive nuclides, due to current analytical limitations and unknown initial isotopic compositions. Here we present interstellar ages of individual presolar SiC grain...

This September we are celebrating the 50thanniversary of the fall of the Murchison meteorite, one of the most important meteorites to science. Since its fall near Murchison, Victoria in September 1969, the Murchison meteorite has been the source of numerous spectacular discoveries. https://sites.google.com/fieldmuseum.org/pritzkercenter/home?authuser=1

Remember that meteor that lit up Chicago’s night sky two years ago? Scientists are searching for it at the bottom of Lake Michigan.

Here is an interesting article in the Chicago Tribune about Project Aquarius, the search for the meteorite that fell into Lake Michigan in 2017. This is accompanied by a short video featuring the Robert A. Pritzker Center and with footage from the recent cruise on the lake.

In 2017, a meteor lit up the winter sky in Wisconsin before plunging into Lake Michigan. It's down there somewhere, says a team of Shedd, Field and Adler scientists, and with a boat and a DIY submersible, their Aquarius Project hopes to find it.

On July 20, 1969, Neil Armstrong took a historic step as the first human on the moon. Buzz Aldrin followed in his footsteps minutes later, and together they collected almost 50 pounds of lunar material. 🌙

Fifty years later, we have some of that lunar soil on loan to us from NASA—what you're seeing here is just one microscopic grain. Jennika Greer is studying these specks of lunar dust to learn more about how space weathering, like exposure to solar wind (particles from the sun), affects lunar soil. The process of space weathering even creates tiny amounts of water that are trapped in the moon's soil.

Jennika's using a technique called atom-probe tomography, which counts and reconstructs the individual atoms of a material. One of the most exciting things about this analysis is that it reveals an empty space in lunar soil that likely once held noble gases from the solar wind. These noble gases could be a valuable resource for a future moon base.

Few things in the Solar System today are old enough to really confirm our Sun’s activity in its early days. ☀️ But minerals from meteorites in our collections are giving clues—and it looks like our Sun had a rowdy start!

Using a garage-size spectrometer in Switzerland, scientists recently found tiny blue crystals called hibonites trapped inside some meteorites. These crystals formed over 4.5 billion years ago and their chemical make-up shows atoms that would only be there if the early Sun was spitting out lots of high-energy particles.

These findings indicate that the Solar System’s oldest materials experienced a phase of irradiation that younger materials avoided, which likely means that a major changed occurred in our nascent Solar System. ☄️ Brush up on your meteorite knowledge: http://bit.ly/TBSMeteorite

Thanks to a donation from meteorite hunter* Robert Ward, our collection now includes a fragment of the meteorite that fell in Michigan on January 16. Because it was found just two days after its fall and was never in contact with liquid water, this is one of the best preserved meteorites in our collection of 1,500+!

Philipp Heck, Associate Curator of Meteoritics, and his team classified the specimen as a chondrite. Chondrites are common and fall a few times a year in the United States, but it's rare that they land in a retrievable place. For instance, last February, a meteorite fell in Lake Michigan, and we're partnering with our friends at the Adler and Shedd in hopes of retrieving it.

By studying meteorites, especially a pristine specimen like this one from Michigan, scientists can peek into the early days of our solar system and learn more about what the temperature, pressure, and minerals of 4.6 billion years ago were like. 🌌

*Yes, a meteorite hunter—as in a very real and very cool way to make a living. 🕵️‍♀️

Kiss of the stars Hello there. This stone has perfect marks of impact and kiss. There is a perfect arc below the kiss marks. From the hickey to the lower arc, it becomes a straight line. The arc should be formed when the temperature of the stone is high and rubbed.
I have some small crinoid fossils I could send you free , if you want them.
hi Not sure the classification but found this in a flea market in Mammoth springs Arkansas. this pic shows a clast surrounded by nickle iron metal , pyroxene and basaltic clasts, some with agglutination. I have some other NWA chondrite rocks I purchased from dean Bessy which also need classification. I also sent you a personal message with mort info. I would like to get them official.
У нас очень интересная находка, не подделка строго. На Марсе нашли кремнезём, такой оттуда первый. Вес 177 г.
