49,000 years ago a small iron asteroid plunged through the Earth’s atmosphere. And though it was small in astronomical terms it created a crater three quarters of a mile across. Scattered around the crater were found starting in the 18802s hundreds of chunks of meteoritic iron. As the years passed after their discovery thousands more […]
Meteorites like any group of rocks have a lot for us to learn. Their mineralogy, degree of alteration and shock, their other unique meteorite features provide a wealth of opportunity for learning about meteorites.

It seems that when the discussion of Martian and Lunar meteorites comes up two questions are always asked. First how do they get to Earth? And secondly, how do you know they are from the Moon or Mars? Most meteorite are pieces of asteroids. Chunks of rock that orbit the Sun and are much smaller […]
With a few notable exceptions meteorites have iron in metallic form as part of their composition. On Earth native iron is truly rare, the moisture and oxygen in the atmosphere quickly convert metallic iron into iron oxide. Well let’s make it simple: rust. So meteorites with metallic iron need to be protected from moisture. In […]
The Earth’s mass is 6,000,000,000,000, 000,000,000,000 kilograms, roughly speaking and that is a lot of kilos. But tomorrow it will be just a little greater. Because today like everyday some rocks and dust fall into our gravity well and get caught. Most of this material will end up in the oceans since three-fourths of the […]
We humans are a species of collectors. Ancients things, new things, art, and oddities are all collected. Included in that list are meteorites. But, why do we collect them? One reason is that meteorites are the rarest of objects on our planet. Far rarer than diamonds or other jewels. Some meteorites have a dollar value […]
Imagine a grass covered expanse with creatures both savage and exotic. Its 49,000 years ago and the North American Continent is in a brief interglacial period of warmth. This warmth has created a lush environment for Woolly Mammoths and other now extinct species. On an otherwise unremarkable day a bright light appears in the sky. […]
The large meteorites seen in museums are often made of nickel iron. That might give one the impression that most meteorites are solid metal. But, the fact of the matter is that most meteorites are made of stone. In geology we talk about stones being made up of minerals. It is that way with meteorites […]
