For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

An international team of astronomers using the NASA/ESA Hubble Space Telescope have made new measurements of Uranus' interior rotation rate with a novel technique, achieving a level of accuracy 1,000 ...

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive ...

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets ...

Somewhere deep below Saturn s cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated. Now, with new Cassini results, a team ...

Hi’iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have ...

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the ...

We have all been taught in school that planets revolve in the same direction as the Earth, i.e., in the counterclockwise direction. However, the universe never ceases to amaze us with its unexpected ...
