Uranus Rotation Period Revised After Decades of Uncertainty

Hubble finds that Uranus is full of surprises after 20-year study

Until recently, Uranus seemed like a fairly calm, blue-green planet. But new findings from Hubble paint a different picture of Uranus.

A Day on Uranus Is Longer Than We Thought, Hubble Telescope Reveals

A new way to measure the length of Uranus’s day could also help determine the rotation rates of other celestial objects—including exoplanets

We Were Wrong About Uranus: New Study Solves Long-Standing Mysteries

New observations have revealed that we were wrong about the length of a day on Uranus.

A day on Uranus just became longer after scientists make groundbreaking discovery

A Uranus day just became longer. The seventh planet from the Sun is a ice giant without a solid surface and an extremely cold temperature and a distinctive tilt, unusual magnetic field, and the surrounding its early history have made it a source of intrigue for planetary scientists.

Scientists determine 'surprise length' of day on Uranus

In the vastness of space, even the smallest discoveries can change our understanding, and Uranus has revealed a new secret.

Hubble Gives Us an Accurate Measurement for Uranus's Day Length

It’s easy to measure the rotation rate of terrestrial planet by tracking surface features but the gas and ice giants pose more of a problem. Instead, previous studies have relied upon indirect measures like measuring the rotation of their magnetic fields. Now a team of astronomers have used the Hubble Space Telescope to refine the rotation rate of Uranus with an incredible level of accuracy. This time though, instead of studying the rotation of …
