Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.

Researchers have now developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet's stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

This is the youngest protoplanet discovered to date. It's location and the surrounding patterns of matter suggest that an alternative method of planet formation may be at work. This discovery could help to explain the histories and features of extrasolar planets seen around other stars.

Superionic ice is a special crystalline form, half solid, half liquid - and electrically conductive. Its existence has been predicted on the basis of various models and has already been observed on several occasions under - very extreme - laboratory conditions. New results provide another piece of the puzzle in the spectrum of the manifestations of water. And they may also help to explain the unusual magnetic fields of the planets Uranus and Neptune, which contain a lot of water.

Along the way, the spacecraft would gather data that would otherwise be impossible to record -- including how comets, Earth-like planets, and even the solar system formed.

The recent discovery offers exciting research opportunities thanks to the planet's substantial atmosphere, small star, and how fast the system is moving away from the Earth.

Such routes can drive comets and asteroids near Jupiter to Neptune's distance in under a decade and to 100 astronomical units in less than a century. They could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.

Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet's existence is at odds with the predictions of leading planet formation theories.

The exoplanet has a mass similar to Neptune, but it orbits a star lighter (cooler) than the Sun at an orbital radius similar to Earth's orbital radius. The results of this research suggest that Neptune-sized planets could be common around this orbital region.

These likely formed at the same time as the Solar System, and understanding their origin could provide important clues as to how the entire Solar System originated. Using sophisticated computer simulations and observations of TNOs, astronomers have shown how these so-called trans-Neptunian Objects (or TNOs) may have formed.

The discovery offers insights into how this volatile mixture can transport material across the moon's surface via geysers, trigger seasonal atmospheric changes, and provide a context for conditions on other distant, icy worlds.

Researchers drove shock waves through two different types of plastic to reach the same temperatures and pressures present inside such planets, and observed the behavior using ultra-strong X-ray laser pulses. Unexpectedly, one of these plastics kept its crystalline structure even at the most extreme pressures. Since the icy giant interiors are made up of the same components as the plastic, planetary models may need to be partially reconsidered.

Scientists recently realized these giant clouds can move and thicken or thin surprisingly rapidly, in less than an Earth day, but did not understand why.

The discovery was made at dawn on June 26 as researchers were testing the Keck telescope to see whether it could make useful observations during twilight, a time most astronomers consider unusable because it's not dark enough.
