Much of the understanding of the seventh planet comes from a brief flyby nearly 40 years ago, which researchers now say overlapped with an exceptional solar event.

The webpage is a New York Times article titled "Uranus Might Have Experienced a Freak Event When Voyager 2 Visited". The article discusses new research suggesting that our understanding of Uranus, primarily based on a five-hour flyby by NASA’s Voyager 2 spacecraft in 1986, might have been affected by an exceptional solar event at that time. Voyager 2's observations showed a magnetosphere devoid of plasma and unusually intense radiation belts, which contradicted the prevailing understanding of planetary magnetospheres.
Recent research by Dr. Jamie Jasinski and his team suggests that an increased solar activity event, known as a co-rotating interaction region, may have coincided with Voyager 2's flyby. This event would have increased the solar wind pressure on Uranus's magnetosphere, shrinking it and explaining the observed anomalies.
The article emphasizes the need for further exploration of Uranus to expand our understanding of the planet. NASA is planning a mission to Uranus in the next decade, which will include placing a probe into the planet’s atmosphere. This new insight into the possible influence of solar activity on Uranus during the Voyager 2 mission underscores the gaps in our knowledge about this distant planet.
