Dutch-Japanese astronomic instrument measures 49 shades of far infrared
The Dutch-Japanese made DESHIMA instrument has passed its first practical tests when measuring the distances and ages of distant galaxies. The core of the instrument is a chip the size of two euro coins that measures 49 shades of far infrared light. The developers of the spectrometer publish the results…

X-raying extragalactic gas: warm-hot gas in the EAGLE simulations
I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Astronomers finally measure polarised light from exoplanet
An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Wild Beasts of the Philosophical Desert: Philosophers on Telepathy and Other Exceptional Experiences
Scientists rarely take ‘paranormal experiences’ seriously. Furthermore, in the recent past the concept of the ‘paranormal’ did not even exist in philosophy. William James, who extensively studied mediumistic phenomena, labelled them ‘wild beasts of the philosophical desert’.

Surprise: No methane on the night side of exoplanet WASP-43b
The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…
