SpaceRock Candy! Eating meteorites is normal, expected, and bad for your teeth.

By Martin Horejsi | November 1, 2025 | Accretion Desk

Every year, I make a few presentations about meteorites and meteorite science to audiences of teachers and students. I’ve done this nationally at science teaching conventions, and locally in small high school classrooms. One thing I really enjoy is the collective gasp when I mention that eating a freshly fallen meteorite is normal, expected even. History is filled with descriptions

Am I Finished Collecting?

By James Tobin | November 1, 2025 | Jim's Fragments

I bought my first meteorite over 57 years ago. I had already found four small irons at Meteor Crater when I was about 15. They were mixed in a box of iron shale and other rocks from the crater until just a few years ago. I did not have the knowledge as a youngster to tell them from the iron

The 2.84 kg meteorite is nearly all pyroxene – mostly iron-free augite and 5% to 20% iron-free enstatite, depending upon the sample. Small opaque spherical grains lie within and between the millimeter size pyroxene grains.

This particular story doesn’t begin with rabbits, rather a minor obsession I have with collecting meteorites with interesting names. It doesn’t matter

LifeShip: Sending Earth to Space

By Melissa Silva | November 1, 2025 | The Little Strangers

In an age of great technological achievement, many of humanity’s most basic, universal questions remain unanswered: how did the solar system come to be? How did the universe come to exist? And, perhaps most relevant to us as a species—how did life itself begin, and why on did this occur on Earth? The transition from non-life to life has never
