Over the last few years, astronomers have observed distant solar systems in their early stages of growth. ALMA (Atacama Large Millimeter/submillimeter Array) has captured images of young stars and their disks of material. And in those disks, they’ve spotted the tell-tale gaps that signal the presence of growing young planets.
As they ramped up their efforts, astronomers were eventually able to spot the young planets themselves. All those observations helped confirm our understanding of how young solar systems form.
But more recent research adds another level of detail to the nebular hypothesis, which guides our understanding of solar system formation.Continue reading “Astronomers See a Newly Forming Planetary Disk That’s Continuing to Feed On Material from its Nebula”
