Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

The Minor in Teaching was introduced in 2009 as a new initiative to introduce and prepare bachelor students for teaching. Student numbers are low, however, especially of mathematics and science students.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Although migration and integration have become important concepts today as a result of globalization, migration movements, integration, and multiculturalism have always been part of the history of Europe.
