Meteorite with CAIs: oldest known solid material in our solar system- the white substance in this meteorite is called Calcium Aluminum rich inclusions (CAIs) and radiometric dating sets the formation time at 4.5673 billion years ago- a few million years older than the rest of the meteorite material and thought to be the first solid compounds formed in the protoplanetary disk before the planets even existed. This substance is most common in carbonaceous chondrites type CV3 as found in this 8 gram sample which was cut and polished on one side. This particular sample was found in 2012 in Northwest Africa. Only the molecules and atoms themselves are older than this CAI material! ➡️ Follow the link in my profile for info on where to get a chunk of meteorite with CAIs and many other amazing items featured here on @physicsfun#meteorite#carbonaceous#chondrite#CAIs#oldestmaterial#deeptime#physics#physicstoy#astronomy#astrophysics#physicsfun#geophysics#geophysicstoy#solarsystem#radiometricdating#inclusion#oldestrock#rockhound#ancient#mineral#geology#science#scienceisawesome
Another image from my Iceland collection. Landmannalaugar shot from a helicopter during an assignment some years ago. This region consists of more geological elements than one can count. Incredible landscape and staggering details everywhere! According to a new green future Index report shared by The World Economic Forum, Iceland is one of the countries best prepared for a green low carbon future. This report measures how countries are reducing their carbon emissions, developing clean energy and innovating in green sectors. The research also looks at environmental protection and government climate policies. #iceland#landmannalaugar#mattiasklum#landscape#fineart#geology@mattiasklumofficial@natgeo@irisalexandrov@alexandrovklumofficial
Large boulders the size of small boulders
On April 29, 2021, the 68th Martian day of the mission, our Perseverance Mars rover took in the rocky view in front of Santa Cruz hill in Jezero Crater. This picture is an enhanced-color mosaic of multiple images. It was created using the left- and right-eye views of Perseverance’s Mastcam-Z camera system.
The rover will pave the way for human exploration of the Red Planet and characterize Mars’s geology and past climate. Perseverance will also be the first to collect and cache samples of Martian rocks, like the ones you see here. These boulders are examples of the kind of rocks the team has called “Ch’al” (pronounced “chesh”), the Navajo word for “frog,” and are about 20 inches (50 centimeters) across on average.
