 Scientists in the University of Chicago's Origins Laboratory have published the latest in a series of papers about the origin of the solar system.

Four and a half billion years ago, the sun may have looked much like one of the baby stars deeply embedded in the cosmic cloud of gas and dust that collapsed to create it. Credit: NASA/JPL-Caltech/L.

A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system. In this study, published online last month in Earth and Planetary Science Letters, authors Haolan Tang and Nicolas Dauphas found the radioactive isotope iron 60 - the telltale sign of an exploding star-low in abundance and well mixed in solar system material.
As cosmochemists, they look for remnants of stellar explosions in meteorites to help determine the conditions under which the solar system formed.
