This image taken with the Atacama Large Millimeter/submillimeter Array (ALMA) shows the young planetary system PDS 70, located nearly 400 light-years away from Earth. The system features a star at its center, around which the planet PDS 70 b is orbiting. On the same orbit as PDS 70b, astronomers have detected a cloud of debris that could be the building blocks of a new planet or the remnants of one already formed. The ring-like structure that dominates the image is a circumstellar disc of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen to the right of the inner rim of the disc.
