Summary

Story summary

A cloud of gas and dust orbits the star J0705+0612, about 3,000 light-years away.
From September 2024 to May 2025, the star dimmed 40 times.
Nadia Zakamska of Johns Hopkins University led Gemini South telescope observations of the cloud.
The cloud spans roughly 120 million miles, shows iron and calcium winds, and may be bound to a planet or brown dwarf.
The findings were published in The Astronomical Journal.

History

Historical Context

In 1992, astronomers Aleksander Wolszczan and Dale Frail confirmed the first exoplanets orbiting the pulsar PSR B1257+12, revolutionizing our understanding of planetary systems beyond our solar system. This discovery challenged previous beliefs about planet formation, as pulsars are remnants of supernovae. Recent observations of a gas and dust cloud around star J0705+0612 further suggest complex interactions in distant star systems, enhancing our knowledge of planetary evolution.
