Black hole one year later: proof of a persistent shadow
The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown by new images released by the Event Horizon Telescope consortium.

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.

Finding the origin of giant black holes
‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

for Leiden astronomy student who simulated chaotic interactions of black holes
Leiden astronomy Master's student Arend Moerman has received an A+ for his thesis research on the simulation of chaotic interactions of three black holes. The simulations, which he carried out together with his Leiden and Oxford colleagues, show that lighter black holes tend to slingshot each other…

Scientists discover the largest stellar black hole in the Milky Way
A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

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…

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.

Design METIS instrument for the Extremely Large Telescope finalised
The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

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…

‘Scientists should be careful when interpreting results of AI models’
Anthropologist Rodrigo Ochigame studies how AI is changing the practice of scientific research. From astrophysics to mathematics to climate science, they find that the adoption of new AI models is raising questions about what counts as reliable scientific evidence.

New generation galaxy formation simulations on the horizon – Evgenii Chaikin received his doctorate with honours
Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

‘The COVID-19 crisis just goes to show how things can go wrong’
Ijeoma Uchegbu is Professor of Pharmacy at University College London (UCL). As a female scientist of colour, she was initially reluctant to play an active role in the university’s diversity policy. Until, that is, she had a radical change of heart: ‘I knew it; I had to become an evangelist.'

BlackGEM telescopes begin hunt for gravitational-wave sources
Three Dutch-Belgian telescopes have started operating at the ESO La Silla Observatory in Chile. This so-called BlackGEM array will scan the southern sky to hunt for cosmic events that produce gravitational waves, such as mergers of neutron stars and black holes. Leiden astronomer Rudolf le Poole is…
