Earth is currently traveling through the Local Interstellar Cloud, a region of gas, dust, and plasma, and a recent study suggests that the solar system may have recently passed through a dense cloud of supernova debris. Evidence for this supernova event includes the presence of the radioactive isotope iron-60.
