First photo of black hole at the heart of our Galaxy
Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

De eerste mensen in de Lage Landen
Nederland ligt in de periferie van het verhaal van menswording. De evolutie van onze familie vindt lang exclusief in Afrika plaats. En, als Europa eenmaal bewoond wordt door mensachtigen, ligt het zwaartepunt ten zuiden van onze streken. Toch heeft ons land een aantal interessante vindplaatsen en vondsten…

Tracking the origin and evolution of molecules in space
How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

Evolutionary Developmental Biology of Bitterling Fish
We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Giant galactic outflows and shocks in the Cosmic Web
The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Spinoza winner Marijn Franx to use successor to Hubble
A permanent exhibition on the place of humans in the cosmos. This is something Franx wants to use his Spinoza Prize for. ‘So much progress has been made that we are still trying to define the questions. In finding the answers we are constantly coming up against surprises.’

Tuning in to star-planet interactions at radio wavelengths
Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

Exploring the Edge
At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Segments and rules: a comparative study into the computational mechanisms underlying language acquisition
In this project we study the properties of statistical- and rule-learning mechanisms in relation to the acquisition and evolution of language. We ask to what extent these mechanisms are unique to humans - or to human language - by comparing the acquisition of vocal structure in two species: humans (infants)…

Revealing the nature of new low-frequency radio source populations
It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

Correcting each other’s mistakes - why cells stuck together in early evolution
The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes
Venomous animals serve as models for a variety of mimicry types. Michael Richardson (IBL) and his international colleagues find that a group of fishes (called fangblennies) evolved venom after the origin of their venom-delivering fangs.
