This ALMA image shows the young planetary system PDS 70. The system features a star at its center, around which the planet PDS 70b (highlighted with a solid yellow circle) is orbiting. On the same orbit as PDS 70b, indicated by a solid yellow ellipse, Balsalobre-Ruza et al. detected a cloud of debris (circled by a yellow dotted line) 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 disk of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen at 3 o’clock right next to the inner rim of the disk. Image credit: ALMA / ESO / NAOJ / NRAO / Balsalobre-Ruza et al.
