Summary

Story summary

Astronomers observed the Type II supernova SN 2024ggi, about 22 million light-years away, with detection on April 10, 2024.
The Very Large Telescope captured images 26 hours after the explosion began.
Spectropolarimetry revealed the shockwave expanded symmetrically but initially took an olive shape.
The results support a jet-driven mechanism for this explosion rather than a neutrino-driven model.
This advances understanding of stellar evolution and explosion processes.
