Extraterrestrial Hypatia stone rattles solar system status quo

Then there are the exotic mineral inclusions. If Hypatia itself is not presolar, both features indicate that the solar nebula wasn‘t the same kind of dust everywhere – which starts tugging at the generally accepted view of the formation of our solar system“, says Kramers.
