NASA’s Voyager 2 flyby of Uranus decades ago shaped scientists’ understanding of the planet but also introduced unexplained oddities. A recent data dive has offered answers. In 1986, Voyager 2's flyby ...

When it came to discovering Neptune, scientists didn’t need to see to believe. The eighth planet in our solar system was ...

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 Voyager 2 spacecraft’s energy budget keeps dropping by about 4 Watt/year, as the plutonium in its nuclear power source is steadily dropping as the isotope decays. With 4 Watt of power less ...

A new study suggests Earth’s Moon may have been “captured” from a binary system, challenging the long-held impact theory and ...
