Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

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

Scientists have identified a rocky outer planet in a system where a gas giant was expected. The discovery challenges ...

If executed at the scale, Musk's orbital data center plan could have devastating effects on the environment and the ...

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

Lawrence Livermore National Laboratory creates a cislunar orbit map to help predict satellite stability and improve collision avoidance in increasingly crowded Earth orbits.

Astronomers found a strange planetary system 116 light-years away. It orbits a red dwarf star called LHS 1903. The planets are arranged in an unexpected order. The outermost planet is rocky, which ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

At a glance, Saturn’s rings appear calm and pristine when observed from afar. These rings are quite narrow and consist mainly ...

Scientists at Lawrence Livermore National Laboratory simulated one million satellite orbits in the vast stretch of space ...
