The Hubble Space Telescope has peered at Uranus, left, and Neptune to study the so-called "ice giant" planets, but little is known about their interior composition. - NASA / ESA / M. Showalter / L.

Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are ...

For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from frozen water, ammonia and methane wrapped in hydrogen and helium. A new ...

The planets Uranus and Neptune are possibly the least explored planetary objects in our solar system. Due to their incredible distances from Earth, the only spacecraft to have visited these awesome ...

We’ve got a pretty good idea about what’s beneath the surface of our nearest planetary neighbors, like Mars. But as you get farther out into the solar system, our knowledge becomes scarce. For ...

NASA’s James Webb Space Telescope has produced the first vertical map of Uranus’s ionosphere, giving scientists a ...

So, it came as a shock to many people when, in 1781, it was announced that a seventh planet, the first to be discovered since ...

Astronomers using three telescopes—one of them the Hubble Space Telescope—have at last solved the mystery of why Uranus and Neptune are different colors. It’s haze. Seventh planet Uranus and eighth ...

Out in the depths of the solar system lie the far-off ice giant planets. Uranus and Neptune are extremely far away at 20 and 30 times farther from the sun than the Earth is, according to NASA, and ...
