Astronomers Find Evidence of an Exomoon Spewing a Volcanic Cloud
Briefly

Astronomers have identified thousands of planets orbiting distant stars, but discovering moons around these worlds remains elusive. A new finding hints at their existence.
The potential moon around WASP-49 b is believed to be ejecting enormous amounts of volcanic material, providing a significant clue to the existence of exomoons.
Jessie Christiansen remarked that the movement of the sodium cloud around WASP-49 b is intriguing, suggesting the possibility of an exomoon that parallels Io's volcanic activity.
The discovery of a sodium cloud suggests hypervolcanic activity possibly linked to a moon, supporting theories that exomoons may abound in the Milky Way.
