    ectives who study meteorites, this variability is inva fuel dispenser luable. For example, radioactivity (which is a fancy name for the way that unstable atomic nuclei break up) depends crucially on the number of neutrons. Particular radioactive isotopes break up into other, non-radioactive isotopes at regular and well-understood rates called half lives (the amount of time it takes half the atoms in a sample to change from one sort to the other). Most famously, uranium-238 decays into lead-206 with a half life of 4.5 billion years, though radioactive rubidium and samarium are also useful for dating things billions of years old. Looking at these isotopes allows the chondrules to be dated, and they were formed 4.56 billion years ago. That, then, is the age of the solar system. But isotopes can do more. They can reach back before the solar system was created, and forward to recor fuel dispenser d the creation of the planets. To reach back, you need to look in the dust grains in chondrites, rather than at the chondrules. Like the chondrules themselves, most dust grains were created in the early solar system—in this case by bigger objects grinding against each other. Modern telescopes can see clouds of dust created in this way around several of the solar system s stellar neighbours. But a few grains have survived from the primitive nebula that the solar system condensed from. This time, it is carbon isotopes that give the game away. To have survived the chaos in which the solar system was born, a grain of dust has to be tough. The toughest materials around are diamond (a type of crystalline carbon) and silicon carbide. Carbon has two non-radioactive isotopes, and in material from the so fuel dispenser lar system, including most meteoritic minerals, these are mixed in a well-known ratio. The carbon in diamond and silicon-carbide grains from meteorites usually has ratios very different from this. The silicon carbide is thought to have come from red giants. These are stars that have swelled up in old age and are nearing the ends of their
