Using one of the world's largest telescopes, a Lawrence Livermore team and international collaborators have tracked the orbit of a planet at least four times the size of Jupiter. The scientists were ...

WASHINGTON, Dec 8 (Reuters) - One of the largest planets ever detected orbits at an enormous distance around two stars with a combined mass up to 10 times greater than our sun, an extreme celestial ...

In a solar system far, far away, astronomers have discovered evidence of possible "sibling" planets sharing the same orbit. The researchers detected a cloud of debris in the same orbital path as an ...

In a real-life twist on Star Wars' Tatooine—a harsh desert planet with twin suns and a criminal underbelly—astronomers have found a bizarre new world that orbits two stars at a perfect right angle.

CLEVELAND — With so much focus on the total solar eclipse right now, I thought some stellar solar system facts would shake up your universe. Let me take you back to grade school and the solar system ...
