NASA recently released a stunning new image of Saturn, depicting the planet's rings shining brightly against the blackness of space. The powerful space telescope has now captured all four gas giants in our solar system.
A gas giant exoplanet 634 light-years away has a quirk in its atmosphere that suggests it may have swallowed a smaller world.
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn.
