This artist conception shows a binary-star, or two-star, system, called HD 113766, where astronomers suspect a rocky Earth-like planet is forming around one of the stars.
This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars. The planet 66-day orbit is tilted 2.5 degrees with respect to the plane of the binary stars orbit.
This artist concept illustrates an imminent planetary collision around a pair of double stars. NASA Spitzer Space Telescope found evidence that such collisions could be common around a certain type of tight double, or binary, star system.
The third closest star system to the sun, called WISE J104915.57-531906, center of large image, which was taken by NASA WISE. It appeared to be a single object, but a sharper image from Gemini Observatory, revealed that it was binary star system.
This diagram illustrates that mature planetary systems like our own might be more common around twin, or binary, stars that are either really close together, or really far apart.
These four images show an artist impression of gas accreting onto the neutron star in the binary system MXB 1730-335, also known as the Rapid Burster.
Observations from NASA Spitzer Space Telescope have revealed that mature planetary systems -- dusty disks of asteroids, comets and possibly planets -- are more frequent around close-knit twin, or binary, stars than single stars like our sun.
This four-panel graphic based on data from NASA's Hubble Space Telescope illustrates how the binary-star system V Hydrae is launching balls of plasma into space.
This graphic shows the relative size of the Sun, upper left, compared to the two stars in the system known as Wolf-Rayet 140. The O-type star is roughly 30 times the mass of the Sun, while its companion is about 10 times the mass of the Sun.
