WD 1145+017 is the name of a star that is very far away in space. This star is very special because it has a planet around it that is being destroyed by the star. The planet is called a "hot Jupiter" because it is very big like Jupiter, but it is very close to its star, so it is very hot.
The way the star is destroying the planet is by pulling it apart with its gravity. The planet is getting so close to the star that it is getting stretched out like spaghetti. When the planet gets close enough to the star, some of it gets swallowed up by the star, and the rest of it gets turned into a big cloud of dust that orbits the star.
Scientists have been studying this star with telescopes to try to understand how planets can be destroyed by stars. They have also been trying to see if there are any other planets around the star that are not being destroyed. They hope that by studying this star, they can learn more about how planets form and survive in other solar systems.
