Astronomers have found a previously unseen type of object circling a distant star.
It could be the core of a gas world like Jupiter, offering an unprecedented glimpse inside one of these giant planets.
Giant planets like Jupiter and Saturn have a solid planetary core beneath a thick envelope of hydrogen and helium gas.
But no-one has previously been able to see what these solid cores are like.
Now, a team of astronomers has discovered what they think are the rocky innards of a giant planet that's missing its thick atmosphere. Their findings have been published in the journal Nature.
