    A temperate exo-Earth around a quiet M dwarf at 3.4 parsec
    The combination of high-contrast imaging and high-dispersion spectroscopy, which has successfully been use to detect the atmosphere of a giant planet, is one of...

    A temperature inversion with atomic iron in the ultra-hot dayside atmosphere of WASP-189b
    Temperature inversion layers are predicted to be present in ultra-hot giant planet atmospheres. Although such inversion layers have recently been observed in...

    A tentative detection of He I in the atmosphere of GJ 1214 b
    The He I λ10833 Å triplet is a powerful tool for characterising the upper atmosphere of exoplanets and tracing possible mass loss. Here, we analysed one transit...

    A tidal tale: detection of several stellar streams in the environment of NGC 1052
    The possible existence of two dark-matter-free galaxies (NGC 1052-DF2 and NGC 1052-DF4) in the field of the early-type galaxy NGC 1052 presents a challenge to...
