Learn about the unexpected discovery that has shaped new perspectives on Uranus' moons and their brightness.

We believe Mars may once have had oceans and sky, but lost them from a lack of a magnetosphere. How does this happen, and how can we create a magnetosphere for Mars so we can terraform and live on it?

Consequently, the Earth's magnetosphere was strongly compressed, resulting in a powerful magnetic reconnection between the interplanetary magnetic field heading south and the Earth's magnetic field.

Voyager 2’s data showed that Uranus’ magnetosphere was home to unexpectedly powerful electron radiation belts. Their intensity was similar to the massive bands of radiation found around Jupiter.

Voyager 2's data on the magnetosphere surrounding Uranus has for decades left scientists perplexed. As a result, Uranus earned a decades-long reputation as an outlier in our solar system.

After reanalyzing the data from the Voyager 2 flyby, the researchers found that the planet's magnetosphere was only compressed to the degree it was observed around 4 percent of the time.
