And how does the effort pay back, not only in terms of astronomical discoveries but also to the whole of society? Four special guests have answered these...
Using ALMA, a team of astronomers have unambiguously detected a moon-forming disc around a distant planet for the first time. The planet is a Jupiter-like gas giant, hosted in a system still in the process of being formed. The result promises to shed new light on how moons and planets form in...
