An adolescent growth spurt in young stars helps giant planets form Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. As the name makes clear, this is where planets form by accreting material from the disk.

Trying to find baby planets swaddled in dust When it comes to finding baby, still-forming planets around young stars, the Atacama Large Millimeter/submillimeter Array (ALMA) observatory is astronomers' most adept tool. ALMA has delivered many images of the protoplanetary disks around young stars, with gaps and rings carved in them by young planets. In new research, a team of researchers used ALMA to image 16 disks around young class 0/1 protostars and found that planets may start forming sooner than previously thought.

Motion of planet-forming spirals captured by ALMA The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the motion of spirals of dust around a young star and shown that the winding motion of the spiral pattern is conducive to planet formation. This provides new evidence for planet formation around this young star. The results could have implications for other young stars as well.
