A bright fireball was observed by a network of all-sky cameras across southern Ontario at 11:37pm on Sunday, April 17, 2022.

Since the discovery of the Adelie Land meteorite in 1912, scientists have plucked more than 45,000 meteorites from the ice in Antarctica.

Meteorites are remnants of the building blocks that formed Earth and the other planets orbiting our Sun.

Ever since scientists started looking at meteorites with microscopes, they've been puzzled--and fascinated--by what's inside.

An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018.

Scientists have offered new insights into the origin of diamonds in ureilites (a group of stony meteorites).

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

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.

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.

Researchers from NASA and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, report that streams of meteoroids striking the Moon infuse the thin lunar atmosphere with a short-lived water vapor.

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.

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.

On 2013 February 15 the approach of asteroid (367943) Duende to our planet was being closely monitored by both the public and the scientific community worldwide when suddenly a superbolide entered the atmosphere above the region of Chelyabinsk in Russia.

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.

A meteorite that fell onto the roof of a house in Novato, California, on Oct. 17, 2012, has revealed a detailed picture of its origin and tumultuous journey through space and Earth's atmosphere.

The discovery of an ancient ring-like structure in southern Alberta suggests the area was struck by a meteorite large enough to leave an eight-kilometre-wide crater, producing an explosion strong enough to destroy present-day Calgary, say researchers from the Alberta Geological Survey and University of Alberta.

As NASA prepares to launch a new Martian probe, a Florida State University scientist has uncovered what may be the first recognized example of ancient Martian crust.

Earth's most eminent emissary to Mars has just proven that those rare Martian visitors that sometimes drop in on Earth -- a.k.a. Martian meteorites -- really are from the Red Planet. A key new measurement of Mars' atmosphere by NASA's Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites.
