We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting closer to their stars than Mercury, and rocky worlds much larger than Earth ...

Astronomers studying a dim red dwarf star called LHS 1903 have found a four-planet system with an architecture that defies the standard rules of how rocky worlds take shape. The outermost planet in ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Of the more than 6,000 known exoplanets in the Milky Way, so-called Sub-Neptunes are the most common. They are smaller than Neptune and more massive than Earth and believed to have rocky interiors ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar ...

Stronger links between researchers who work on Earth’s and other planets’ atmospheres, and between the experimental, modelling and observational communities, will help to interpret the astronomical ...

New research uses laboratory experiments to demonstrate that water is naturally created during the planet formation process. By squeezing and heating planetary analog materials between the tips of two ...
