Summary

Story summary

Astronomers discovered Calvera, a runaway pulsar 6,500 light-years above the Milky Way, challenging star formation theories.
Calvera is associated with a supernova explosion from 10,000 to 20,000 years ago.
Research shows X-ray and gamma-ray emissions can occur in low-density regions, enhancing our understanding of cosmic processes.
Findings were published in Astronomy & Astrophysics on August 29, 2025.
