High-mass stars are formed not from dust disk but from debris
A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic mess. The researchers used the Atacama Large Millimeter/submillimeter…

Historical continuity helped form Dutch and Belgian identities
Dutch people are far more law-abiding than they might like to think. And they are very different from the Belgians in that regard. The different approaches of the two governments towards the coronavirus crisis, for example, can be explained from the history of both countries since the Middle Ages. Historians…

‘Heritage decisions limit our ability to imagine alternative forms of society’
It is difficult to imagine a society other than a hierarchical nation-state. This is in part because we neglect alternative forms from the past, argues archaeologist Lewis Borck in the Journal of Contemporary Archaeology.
