Moon rocks reveal new clues about Theia – the planet that disappeared in the collision that formed the moon

Precise analysis of iron isotopes in rocks from Earth and the Moon reveals that Thea – the body whose impact created the Moon – was likely born in the inner part of the solar system, even closer to the Sun.

So close! A small asteroid passed 428 km above Antarctica

A space rock 1–3 meters in diameter passed at an altitude similar to the ISS orbit; it was discovered hours after the pass, and observations from the Las Cumbres Observatory allowed for a precise trajectory determination
NASA's Perseverance spacecraft captured this selfie, made up of 62 individual images, on July 23, 2024. A rock called Chiave Falls—where features have been found that may indicate whether Mars was once home to microscopic life—is visible to the left of the spacecraft, near the center of the image.

Signs of life on Mars? Geologists warn: It may be non-biological processes

Case Western Reserve University researchers are cooling the enthusiasm for the Mars Perseverance rover's discoveries, emphasizing that the spotted rocks found may have been formed by geological processes – not by microorganisms.

The asteroid Bennu is a time capsule of materials that testify to its origin and the changes that have occurred over billions of years.

Three papers by a team of researchers who analyzed samples from OSIRIS-REx, led by the University of Arizona, reveal unprecedented details about the composition and history of asteroid Bennu

Scientists date Jupiter's origin using ancient 'raindrops' of molten rock

Researchers have developed computer simulations of Jupiter's growth and tracked how its gravity caused rapid collisions between rocky and water-rich planetesimals in the early solar system.

Scientists may have solved a space rock mystery that could change our understanding of the beginnings of life

An international study has found that carbon-rich meteorites are rare on Earth because they break up in space or burn up in the atmosphere, which could change our understanding of the origin of life.

Supersonic booms in the sky: How scientists are using bolides to improve planetary defense

Researchers show that bolides – meteoroids that explode in the atmosphere – create sound waves that can be analyzed for warning purposes about space debris and other astronomical threats

The asteroid the size of four Everests that changed the course of life on Earth

It turns out that these giant meteorites actually had a positive effect on life compared to the later extinction-causing meteorites
El Médano 128 meteorite, a regular chondrite (L group), was found in the Atacama Desert in 2011 by a team of researchers from the Research and Teaching Center for Environmental Geosciences (CEREGE - University of Aix-Marseille/CNRS/INRAE/IRD). Credit: © Jérôme Gatakzka, CNRS, CEREGE

70% of the meteorites that landed on Earth came from a small number of collisions in the asteroid belt

A new study reveals that most of the meteorites on Earth were formed as a result of collisions that occurred in the asteroid belt in the last tens of millions of years. The discovery provides new insights into the origins of meteorites and the possible threat to Earth

The asteroid that wiped out the dinosaurs was a carbonaceous asteroid

This asteroid, which led to the extinction of the dinosaurs, came from a C-type asteroid that originated beyond Jupiter, thus ruling out other hypotheses such as volcanic activity or comets

Target board or donut? Iron meteorites reveal the early form of our solar system

The formation of our solar system involved the accretion of gas and dust into a preplanetary disk, with meteorites providing important insights into its early composition.

Artist's impression of early Mars bombarded by an asteroid larger than Texas. The scientists believe that the impact caused the Martian crust to melt in the northern hemisphere, sending fragments into space and sending shock waves through the planet's molten core. This explains why the Martian crust is thinner in the northern hemisphere. Photo: Jeff Anders-Hannah and Francis Nimmo.
