Astronomers have observed a remarkable arrangement in a young binary star system which is giving birth to three separate systems of planets. The team also found within the three planet-forming disks of gas and dust, complex organic molecules that could, in the future, seed life on the planets that form.

The team discovered that there is not one, or two, but three planet-forming disks in the double-star system designated SVS 13 and located around 980 light-years from Earth. Each star is surrounded by one disk of gas and dust that form the building blocks of planets, and there is also a larger disk surrounding the entire binary system.
