Black holes are sometimes gigantic volcanoes. Martijn Oei earned his PhD on the subject, with honours
Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

How the speed demons of the universe tell us something about the Milky Way
They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Motion of stars near Milky Way's central black hole is only predictable for few hundred years
The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

Willem van der Does sheds new light on the at times pitch-black history of psychiatry
Piercing through the skull with an ice pick, administering electric shocks without an anaesthetic, or applying leeches to the uterus: these may seem like medieval methods of torture, but they are in fact therapies used in medicine. Willem van der Does writes about all of them in his new book. ‘Physicians…

Sjoert van Velzen receives Vidi grant to solve 'riddles from the universe'
Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Galaxies have bipolar gas outflows far into intergalactic space
For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…
