NASA artist's depiction of an extra-solar system crowded with giant planets. Scientists have found that the presence of gas giants in a solar system is likely to prevent life from forming.

While our solar system’s gas giants are far from the sun, the core of a gas giant is likely to be incredibly hot–Jupiter’s is estimated at around 43,000 degrees Fahrenheit.

A gas giant is a large planet that is not primarily composed of rock or other solid matter. Gas giants may have a rocky or metallic core—in fact, such a core is thought to be required for a gas ...

Gas giants that orbit very close to stars are normally loners. But this one has a friend. By Briley Lewis Published May 24, 2023 6:00 AM EDT ...

But not every gas giant is so lucky; some of them should be too close to their parent stars, where their volatile gas atmospheres are boiled away. Here’s what’s left behind.

The differences with our local gas giant—larger radius but smaller mass—are probably a result of the small distance between NGTS-1b and its star, which heats and expands the gas of the planet.
