SCIENCE ALERT - Planets with two suns have intrigued our cosmic imagination ever since they appeared in a popular work of fiction set in a galaxy far, far away.
That's right, the globally famous King in Yellow, published in 1895. Oh, and Star Wars, of course.
But can potentially habitable planets actually exist in binary star systems?
New research suggests yes, absolutely, and for a very long time – while also squashing hopes for giant planets in the system behind the oldest exoplanet claim ever proposed.
Our Solar System is unusual because it's the only one we know of with robots zipping between its planets.
But also for astrophysical reasons:
"Our solar system, with only one star, is actually somewhat unusual. Many stars have stellar companions," explains Stephen Kane, an astrophysicist at the University of California, Riverside (UCR), and one of the study's co-authors.
