Summary

Story summary

Scientists using South Africa's MeerKAT telescope detected radio emissions from interstellar comet 3I/ATLAS, confirming its natural origin.
The signals relate to hydroxyl radicals, indicating typical cometary activity.
This detection followed earlier unsuccessful attempts and coincided with the comet's perihelion on October 29.
Despite unusual characteristics, the scientific consensus remains that 3I/ATLAS is a natural object.
Future observations are planned, including a close approach to Jupiter in March 2026.

History

Historical Context

Comet Hale-Bopp, discovered independently by Alan Hale and Thomas Bopp on July 23, 1995, became one of the most observed comets in history. Its perihelion on April 1, 1997, revealed a brightness exceeding predictions, captivating 69% of Americans. The comet's extensive study advanced cometary science, enhancing understanding of solar system formation and influencing future missions, including observations of comet 3I/ATLAS in 2026.
