Massive Planets May Punch Puzzling Holes in Planetary Nurseries

Now, observations of four young stars using the Atacama Large Millimeter/submillimeter Array (ALMA), have led researchers to conclude that Jupiter-class planets in the neighborhood around those stars are clearing out the debris near the star, effectively poking a hole in the middle of the disc, according to a statement from the European Southern Observatory (ESO), one of the partner organizations that runs ALMA. The new finding was performed while the observatory was under construction, with onl
