Young Planetary Systems: ngVLA Science Case
The Atacama Large Millimeter/submillimeter Array (ALMA) has shown us young star systems where planets are forming. The next-generation Very Large Array will go even deeper, observing Earth-size bodies in their youth. It will reveal how planets clear gaps in cold, dusty planetary disks. The ngVLA will also study how stellar winds clear primordial gas and dust from star systems.
To balance their speeds out to those distances from their massive central cores, the galaxies must be made of more stuff than just that which we can detect.
