Scientists Discovered A Rare Mineral In An Asteroid That Is Older Than The Planet Earth, Having Roamed The Universe For Billions Of Years Before Hitting The Ground
Among the mineral treasures that Earth harbors, some are truly extraordinary, transcending our planet and connecting us to the cosmos. Krotite, a mineral that is older than Earth itself.
Krotite formed under extreme conditions billions of years ago, transporting us back to the dawn of the Solar System. Discovered in 2011, a krotite was identified in a meteorite fragment called NWA 1934, found in Africa.
This piece of space rock roamed the universe for billions of years before falling to Earth. Its formation occurred at temperatures above 1,500 degrees Celsius, in low-pressure environments—conditions that can’t be naturally replicated on our planet today.

Obsessed with eliminating water waste, a factory in SC invests R$ 5 million, reduces consumption from 48,000 to just 3,000 liters per day, and today supplies about 70% of the flexographic market in Latin America.

Truck drivers can retire diesel: technology refuels in just 8 minutes, reaches up to 700 km of range, and emerges as an alternative for a fleet that still depends 99% on the fuel responsible for 47% of the sector’s emissions.

What seemed impossible has been confirmed by researchers from Germany: fish sleep in ways very different from humans and use mechanisms developed over millions of years to conserve energy and increase their chances of survival.

Yeast used in bread, beer, and pizza becomes biomaterial for architecture and surprises by forming lightweight pieces, molded in 3D printers and dried without high energy consumption heating.
An Ancient And Mysterious Mineral
Krotite was born in the protoplanetary disk surrounding the young Sun 4.6 billion years ago. This environment, filled with dust and gases at high temperatures, was the cradle of various celestial bodies, including planets.
Its composition, a combination of calcium, aluminum, and oxygen, reflects the violent and intense conditions of that period.
Meteorites like NWA 1934 act as time capsules, preserving minerals in their original state. Unlike terrestrial rocks, which are constantly reshaped by tectonic activity and erosion, these space fragments provide a pristine view of the past.
The analysis of krotite allows scientists to explore the processes that shaped our Solar System, from planet formation to the emergence of complex chemical elements.
Cosmic Concrete
Interestingly, humanity has already created something similar to krotite. Certain types of concrete, specifically calcium aluminate cement, have a similar chemical composition. However, there is one crucial difference: while krotite exhibits a specific crystalline arrangement, man-made materials have distinct atomic structures, resulting from their formation conditions.
Another mineral found exclusively in meteorites, dmitryivanovite, shares chemical similarities with krotite. Both are named after renowned scientists. Krotite was named in tribute to Alexander N. Krot, a cosmochemist who significantly contributed to the study of the primitive Solar System, while dmitryivanovite honors Dmitriy A. Ivanov, a prominent geologist.
A Window To The Cosmic Past
The composition and structure of krotite reveal fascinating clues about the early Solar System. Research suggests that minerals like it formed from condensation and crystallization processes in the hot, gaseous environment of the solar nebula. These processes involved different minerals surrounding the initial cores, followed by partial melting events and complex chemical reactions.
Studying krotite is like turning the pages of a cosmic book. Each mineral detail provides answers about the conditions leading to the origin of planets, moons, and other celestial bodies. For instance, the calcium and aluminum-rich inclusions (CAIs), of which krotite is a part, help understand how primordial material is specified to form the building blocks of planets.
Geology Above Our Heads
The discovery of krotite also reinforces a truth often overlooked: geology extends beyond Earth. It permeates the universe, connecting us to events and processes that occurred billions of years before our planet even existed. The analysis of extraterrestrial minerals broadens our understanding of the cosmos and challenges our perceptions of time, space, and evolution.
Even as a tiny and modest fragment, krotite carries significant weight. It is a tangible reminder of the vast scales of time and the immense forces shaping the universe. More than a mineral, it is a key piece in the cosmic puzzle that helps us unravel our own origin.
The next time we look at the sky, we may remember: among the stars, there are stories etched in minerals like krotite, waiting to be discovered. After all, geology is not just beneath our feet—it is also above our heads, in lost fragments of the cosmos.
