For decades, scientists puzzled over why Uranus seemed colder than expected. Now, an international research team led by the University of Houston has solved the mystery: Uranus emits more heat than it gets from the Sun, meaning it still carries internal warmth from its ancient formation. This revelation rewrites what scientists know about the ice giant’s history, strengthens the case for NASA’s upcoming mission, and offers fresh insight into the forces shaping not only other planets, but also Earth’s future climate.

A new study led by University of Houston researchers, in collaboration with planetary scientists worldwide, suggests Uranus does have its own internal heat — an advance that not only informs NASA’s future missions but also deepens scientists’ understanding of plan...

Neptune is fondly known for being a rich blue, and Uranus green—but a new study has revealed that the two ice giants are actually far closer in color than typically thought.

The correct shades of the planets have been confirmed with the help of research led by Professor Patrick Irwin from the University of Oxford, which has been published today in the Monthly Notices of the Royal Astronomical Society.

He and his team found that both worlds are in fact a similar shade of greenish blue, despite the c...

The James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features—including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look.

With its exq...

Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between 2 to 4X the size of Earth. It will have implications for the search of life in our Galaxy. The work is presented at the Goldschmidt conference in Boston.

The 1992 discovery of exoplanets orbiting other stars has sparked interest in understanding the composition of these planets to determine, among other goals, whether they are suitable for the development of life. Now a new evaluation of data from the exoplanet-hunting Kepler Space Telescope and the Gaia mission indicates that many of the known planets may contain as much as 50% water. This is much more than the Earth’s 0.02% (by weight) water content...
