    A giant planet candidate transiting a white dwarf
    Astronomers have discovered thousands of planets outside the Solar System 1, most of which orbit stars that will eventually evolve into red giants and then into...

    A giant planet transiting a 3-Myr protostar with a misaligned disk
    Astronomers have found more than a dozen planets transiting stars that are 10–40 million years old 1, but younger transiting planets have remained elusive. The...

    A giant radio galaxy with three cycles of episodic jet activity from LoTSS DR2
    The excellent sensitivity and optimum resolution of LoTSS DR2 at 144 MHz has enabled us to discover a giant radio galaxy (J1225+4011) with three distinct...

    A giant thin stellar stream in the Coma Galaxy Cluster
    The study of dynamically cold stellar streams reveals information about the gravitational potential where they reside and provides important constraints on the...

    A giant umbrella-like stellar stream around the tidal ring galaxy NGC 922
    Context. Tidal ring galaxies (TRGs) are rarely observed in the local universe due to their intrinsically transient nature. The tidal ring structures are the...

    A glint in the eye: Photographic plate archive searches for non-terrestrial artefacts
    In this paper, we present a simple strategy to identify Non-Terrestrial artefacts [NTAs; Haqq-Misra and Kopparapu (2012)] in or near geosynchronous Earth orbits...

    A global view on the colliding-wind binary WR 147
    We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with the Gran Telescopio Canarias...

    A gravitational-wave standard siren measurement of the Hubble constant
    On 17 August 2017, the Advanced LIGO and Virgo detectors observed the gravitational-wave event GW170817—a strong signal from the merger of a binary neutron-star...

    A GTC spectroscopic study of three spider pulsar companions: line-based temperatures, a new face-on redback, and improved mass constraints
    We present GTC-OSIRIS phase-resolved optical spectroscopy of three compact binary millisecond pulsars, or 'spiders': PSR J1048+2339, PSR J1810+1744, and (for...
