Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

National media outlets such as NRC Handelsdagblad and NPO 1 Radio…

Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

Astronomers have captured a new deep field of Pandora's Cluster (Abell 2744) with the James Webb Space Telescope. The images show never-before-seen details. The results are described in four scientific papers. Leiden astronomers Marijn Franx and Mariska Kriek collaborated on the study. 'This opens a…

Jasper Knoester startte op 1 januari als onze nieuwe decaan. Hoe gaat het met hem, wat doet hij precies en hoe ziet zijn dag eruit? In elke nieuwsbrief geeft Jasper een inkijkje in zijn leven als decaan.

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…

The Indonesian government has been trying to enforce marriage and divorce laws for some time. These efforts are encountering resistance from both local communities and the Indonesian Supreme Court. PhD candidate Al Farabi investigated where this resistance comes from.

In a new article in the journal Scientific Reports, Leiden archaeologist Wei Chu and colleagues report on recent excavations in Western Romania at the site of Româneşti, one of the most important sites in southeastern Europe associated with the earliest Homo sapiens. The site gives an important glimpse…

In a recent study, Dr. Moji Aghajani and colleagues show that adolescents with a severe form of Conduct Disorder (CD) -with limited prosocial emotions- require an unusually large amount of brain capacity to read emotional faces.

Lecture, Histories Connected: Work-in-Progress

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of…

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.
