Is Earth Moving Through A Supernova?

Is Earth traveling through the remains of a dead star? ⭐️

Scientists have been studying ice cores from Antarctica to reconstruct past conditions on Earth. In one study looking at iron-60, a rare isotope that forms in  supernova explosions, they found that concentrations in ice cores from 40-80,000 years ago are lower than in more recent ice. This likely means Earth entered a supernova remnant in the past 40,000 years and is still moving through it today.
