Spread across the southwestern Algerian Sahara, spilling over the borders into Mali and Mauritania, lies a sea that has no water. The Erg Chech is an ocean of sand - 206,000 square kilometers of it, larger than many nations, the third-biggest sand sea in the entire Sahara. There are no towns to speak of, no roads worth the name, almost no people at all. And yet this near-empty expanse once delivered a rock that rewrote part of the story of how our solar system began.

An erg is a true sand sea - not the rocky, gravel-strewn desert most of the Sahara actually is, but mile upon mile of dunes. The Erg Chech has them in every form: long linear ridges marching in parallel, complex compounds where ridges collide, and star dunes that radiate arms in ...

In July 2007, a fireball blazed across the sky north of Taoudenni and stones rained down across an elliptical strewn field; over the following months, meteorite hunters collected roughly 100 kilograms of fallen rock from a scatter known as the Chergach strewn field. Then, in 2020...

Erg Chech 002 did more than break an age record. Because the rock crystallized so early, it preserved a chemical snapshot of the cloud of gas and dust from which the planets condensed. Scientists studying it found evidence that aluminium-26 - a radioactive isotope that acted as o...

It is tempting to call the Erg Chech featureless, but that misses what it is. This is a landscape stripped to essentials - sand, sun, wind, and silence on a scale almost impossible to grasp from the ground. The same emptiness that makes it nearly uninhabitable is exactly what mak...
