A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

The orbits of the planets around the sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Astronomers have uncovered a rare exoplanet, HD 143811 AB b, that orbits two parent stars, mirroring the twin-sun system of Tatooine from Star Wars. This planet, however, presents an intriguing ...

Scientists using NASA’s James Webb Space Telescope have found a unique planet in another star system that’s shaped like a lemon. The lopsided Jupiter-style planet is so bizarre that it may blur the ...
