    Relativistic jets observed from transient neutron stars throughout the Universe produce bright flares for minutes after each X-ray burst, helping to determine the role individual system properties have on the speed and revealing the dominant launching mechanism.

    X-ray observations of two large glitches bracketing a fast radio burst in the active Galactic magnetar SGR 1935+2154 reveal a connection between rapid spin change and radiative behaviours of the magnetar.

    A type II supernova (SN 2023ixf) was observed in the galaxy M101 at a distance of 6.85  ±  0.15 Mpc, at about 1.0  h after the explosion.

    Observations of optical flares from AT2022tsd (the ‘Tasmanian Devil’) show that they have durations on the timescale of minutes, occur over a period of months, are highly energetic, are probably nonthermal and have supernova luminosities.

    The discovery of a long-period radio transient, GPM J1839–10, prompted a search of radio archives, thereby finding that this source has been repeating since at least 1988.

    A type Ia supernova shows the presence of helium-rich circumstellar material, as demonstrated by its spectral features, infrared emission and a radio counterpart, that probably originates from a single-degenerate system in which a white dwarf accretes material from a helium donor star.

    Observations of ZTF SLRN-2020, a short-lived optical outburst in the Galactic disk accompanied by bright, long-lived infrared emission, show that the resulting light curve and spectra are consistent with the signatures of a planet being engulfed by its host star.

    A possible kilonova associated with a nearby, long-duration gamma-ray burst suggests that gamma-ray bursts with long and complex light curves can be spawned from the merger of two compact objects, contrary to the established gamma-ray burst paradigm.

    Analysis of the pulse profile of a fast radio burst showed sub-second periodicity, providing evidence for a neutron-star origin of the event and favouring emission arising from the magnetosphere.

    The fast radio burst FRB 20200120E is shown to originate from a globular cluster in the galaxy M81, and may be a collapsed white dwarf or a merged compact binary star system.

    Analysis of archival low-frequency radio data from the Murchison Widefield Array reveals a periodic transient with an unusual periodicity of 18.18 min, the source of which is localized to our Galaxy and could be an ultra-long-period magnetar.

    The southern hemisphere of Betelgeuse during its Great Dimming was an order of magnitude darker than usual, owing to a cool patch on the photosphere and associated dust formation.

    Observations of the fast radio burst FRB 200428 coinciding with X-rays from the Galactic magnetar SGR 1935+2154 indicate that active magnetars can produce fast radio bursts at extragalactic distances.

    A periodicity of roughly 16 days is detected for the fast radio burst 180916.J0158+65, suggesting that the burst arises from a periodically modulated mechanism instead of a cataclysmic or sporadic process.

    The relativistic jets associated with the black-hole X-ray binary system V404 Cygni change their orientation on time scales of minutes to hours, implying that the direction of the jets is being affected by the dynamics of the surrounding accretion flow that powers them.

    A second repeating fast radio burst is detected, showing behaviour similar to that of the first, and demonstrating that repeaters are unlikely to be rare.
