A gas bubble 22,000 times larger than Earth was expelled by Uranus.
In 1986, Uranus discharged a gas bubble that was 22,000 times larger than Earth, and recent discoveries by two planetary scientists suggest that it may happen again. Upon examining NASA’s archives, the scientists observed a blip in Uranus’s magnetic field while traversing a magnetic bubble. This new information was published in Geophysical Research Letters last summer and has piqued the interest of planetary scientists who are now focusing on addressing the most pressing unanswered questions in the field.
Although the Voyager 2 spacecraft captured evidence of this phenomenon, researchers initially overlooked it. However, it was later confirmed that in 1986, during its flyby of Uranus, the spacecraft observed a large bubble of gas being expelled from the planet’s atmosphere. Specifically, Voyager 2 detected a brilliant plume of gas emanating from the southern hemisphere of Uranus. The plume was enormous, measuring about 8,000 kilometers (5,000 miles) in width and stretching 27,000 kilometers (17,000 miles) above the planet’s surface, making it approximately 22,000 times the size of Earth.
The sudden discharge of gases from deep within Uranus’ atmosphere is believed by scientists to be responsible for the plume, and the exact cause of this occurrence remains partly unclear. However, it is speculated that the planet’s severe tilt, resulting in extreme seasonal fluctuations, may be linked to it. This event was noteworthy because it offered scientists novel perspectives on Uranus’ atmospheric dynamics and helped them gain a better understanding of the planet’s intricate weather patterns.
