Meteorite

Meteorites often burn up in Earth’s atmosphere, but a fireball over Canada last year may shake up our understanding of the solar system. Scientists traced its origins back to a distant cloud of comets that wasn’t thought to host any rocky material.

Scientists have discovered at least two new minerals inside one of the largest meteorites ever found. The iron-based minerals have never been spotted in nature, and could hint at unknown geological processes and new material uses.

NASA’s InSight Mars lander has made two major new discoveries. By sensing seismic activity from the Red Planet, the craft has now detected a large meteorite impact, and found evidence of magma pools and volcanic activity still occurring today.

Rare earth elements are vital for electronics, but they’re in short supply. Now scientists have recreated a promising alternative – a “cosmic magnet” that normally takes millions of years to form in meteorites is cooked up in the lab in seconds.

Australian scientists have discovered strangely folded diamonds in rare meteorite samples. In investigating how they came to form, the team found evidence that they were forged in a cataclysm on an ancient dwarf planet.

Evidence is mounting that the key building blocks of life may have been delivered to our home planet from space. Scientists have now identified in meteorites the last two DNA nucleobases that hadn’t yet been found in extraterrestrial samples.

Researchers have discovered a new mineral in a meteorite from the Moon. Named donwilhemsite, the mineral appears to form under high pressures and may play a crucial role in the rock cycle deep within the Earth.

A new study by the Centre de Recherches Pétrographiques et Géochimiques in Nancy, France suggests that Earth's water may have come from stony meteorites in the inner solar system rather than distant comets from billions of miles away.

One small, particularly puzzling group of meteorites appears to have been both solid rock and liquid metal. Now scientists have determined that the parent body had a rocky shell and a liquid metal core, which likely generated a strong magnetic field.

Scientists have discovered a full, previously-unknown protein inside a meteorite for the first time. Named hemolithin, the new protein contains iron and lithium and may play an important role in seeding life on habitable planets like Earth.

Scientists have identified the oldest impact site ever to scar our planet’s surface. The body that formed the Yarrabubba crater in the Australian outback struck Earth 2.229 billion years ago, and may have helped end a global ice age.

Researchers have discovered the oldest material on Earth – and it’s not from Earth. Tiny grains from a meteorite that fell in Australia were found to be between 5 and 7 billion years old, meaning they predate our planet, the Sun and the solar system.
