Summary:

- The article discusses a new study that challenges the long-held belief that Jupiter-like exoplanets, known as "hot Jupiters," are isolated "lonely giants" in their planetary systems.

- The study, published in the Astrophysical Journal, analyzed observations of the exoplanet WASP-132b, which orbits a Sun-like star, and found that it has a previously undetected companion planet.

- This discovery suggests that hot Jupiters may not be as isolated as previously thought and that they can have smaller companion planets, providing new insights into the formation and evolution of planetary systems.
