Looking at the birth of planets - space short science news

Astronomers have acquired new insights into the speed with which planets can form by studying protoplanetary disks, the belts of dust and gas around young stars. The observations were made with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

The most striking finding was that that large planets the size of Neptune or Saturn from quickly, much faster than current theories hold for possible. Also, rocky planets like Earth can form without falling into their star by finding shelter in de protoplanetary disk.

These and other observations are described in a series of papers in Astrophysical Journal Letters.
