This PhD project investigates the different uses of Mandarin

A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

16 April was a special day at the Faculty of Science. In honour of the collaborations with the Chinese partner university, it was declared Xi’an Jiaotong University Day.

The discovery of a planet far too large for its sun defies models about the formation of solar systems and planets. In a paper in Science, researchers, including Yamila Miguel of Leiden Observatory, report the discovery of a planet more than 13 times heavier than Earth orbiting the ultracool dwarf star…

Astronomer Joseph Callingham and his team have observed for the first time a clear signal from a giant burst from a star outside our solar system. This would have a devastating impact on any unfortunate planet orbiting the star.

International researchers have, for the first time, pinpointed the moment when planets began to form around a star beyond the Sun. Using the ALMA telescope, in which the European Southern Observatory (ESO) is a partner, and the James Webb Space Telescope, they have observed the creation of the first…

A vitamin D deficiency is often associated with smoggy English industrial cities during the Industrial Revolution, but research carried out on skeletons now suggests that the ‘English disease’ was also prevalent in rural areas of the Netherlands. Doctoral defence on 29 January.

All comets might share their place of birth, new research says. For the first time ever, astronomer Christian Eistrup applied chemical models to fourteen well-known comets, surprisingly finding a clear pattern. His publication has been accepted in the journal Astronomy & Astrophysics.

Using the Dutch-led Low Frequency Array (LOFAR) radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151.
