When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site?

New work led by Carnegie's Peng Ni and Anat Shahar uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites.

The composition of Antarctic micrometeorites and other tiny but precious rocks such as those from space missions--is really hard to analyze without some sample loss.

Most meteorites that have landed on Earth are fragments of planetesimals, the very earliest protoplanetary bodies in the solar system. Scientists have thought that these primordial bodies either completely melted early in their history or remained as piles of unmelted rubble.

Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time.

The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size ∼100 m.

Scientists have found that 4.02 billion year old silica-rich felsic rocks from the Acasta River, Canada - the oldest rock formation known on Earth - probably formed at high temperatures and at a surprisingly shallow depth of the planet's nascent crust.

Researchers have identified a new type of meteorite with the potential to reshape our understanding of planetary formation.

In 2013, researchers announced that a pebble found in south-west Egypt, was definitely not from Earth.

LISA Pathfinder, a mission led by the European Space Agency (ESA) with contributions from NASA, has successfully demonstrated critical technologies needed to build a space-based observatory for detecting ripples in space-time called gravitational waves.

More than 100 billion micrometeorites (MMs) fall to Earth each year. Until now, scientists believed that these particles could only be found in the cleanest environments, such as the Antarctic.

A meteorite impacting the earth under a grazing angle of incidence can do a lot of damage; it may travel a long way, carving a trench into the ground until it finally penetrates the surface.

Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids.
