This image released by The European Southern Observatory on July 23, 2021, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the PDS 70 system, located nearly 400 light-years away and still in the process of being formed. The system features a star at its centre and at least two planets orbiting it, PDS 70b (not visible in the image) and PDS 70c, surrounded by a circumplanetary disc (the dot to the right of the star). The planets have carved a cavity in the circumstellar disc (the ring-like structure that dominates the image) as they gobbled up material from the disc itself, growing in size. It was during this process that PDS 70c acquired its own circumplanetary disc, which contributes to the growth of the planet and where moons can form. - Astronomers have reported the first unequivocal detection of a disk of gas and dust encircling a planet outside our solar system that is likely to form moons.
