In ancient Greece and Rome, nighttime encompassed a distinctive array of cultural values that went far beyond the inversion of daytime. Night was a mythological figure, a locus of specialized knowledge, a socially significant semantic space in various literary genres, and a setting for unique experi…

In the past 30 years, over 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of these. Those simulations provide guidance for astronomers…

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,…
