Radio images from the Low Frequency Array have revealed complex, filamentary radio emission around a radio galaxy undergoing multiple episodes of radio outbursts, showcasing the importance of magnetic fields for the survival of radio filaments far from the radio core.

Cosmological simulation TNG50 reveals that a recently discovered population of isolated but non-star-forming ultra-diffuse galaxies may have been gas-rich satellites of much more massive galaxies in the distant past.

Recent observations show that some galaxies exist that have already run out of fuel only a few billion years after the Big Bang, challenging the current view on how galaxies form and evolve in a cold dark-matter-dominated Universe.

The standard model of terrestrial planet formation ignores the role of orbital migration of planetary embryos. A new scenario shows how migration may have sculpted the inner Solar System’s orbital architecture, as long as embryos converged towards about 1 au.

A supernova, possibly of type Ia, gravitationally lensed by a massive cluster, is predicted to appear in the future. It has the potential to allow an independent, high-precision measurement of the Hubble constant.

Our view of fast radio bursts — millisecond duration pulses of high intensity — has gained significant clarity following the discovery of hundreds of sources that are helping us to understand the nature of this enigmatic phenomenon.

The measured blue and redshifts of galaxies within filaments in the local Universe are consistent with the large-scale flow of matter within walls, but they may also point to evidence for their rotation.

The association of a short gamma-ray burst with a core-collapse supernova seems to challenge current scenarios for the origin of these extreme events. But how much can we rely on observed duration for pinpointing their progenitors?

New extremely high-resolution observations of the radio jets of the active galaxy Centaurus A have revealed striking brightening at the jet edges. This may be a common feature of jet outflows from active galaxies, but its origin remains unclear.

The behaviour of minerals under high pressure affects the bulk properties of exoplanets and planets with rocky components, possibly influencing their observable radii. Obtaining a wide range of experimental data is key to understanding observations and informing planetary interior models.

Turmoil has engulfed the solar community for decades about which physical mechanisms are sufficient to trigger and drive solar eruptions. New high-resolution numerical magnetohydrodynamic simulations bring an old idea back into the light: the reconnection jet from the tether-cutting model.

Novel observational evidence appears to confirm that when mass is supplied to massive black holes at low rates, only a fraction is actually accreted. Much of the gas may be lost in a low-speed magnetohydrodynamic wind.

The fate of galaxies is predominantly determined by their dark matter halo mass. However, recent simulations confirm an important role for the formation history, revealing an intricate relation between galaxies’ central supermassive black holes and the colours of their hosts.

Observations from the brand-new CHEOPS mission reveal a third long-period transiting planet around the naked-eye star ν² Lupi. Precise measurements of the masses and radii of planets around this star show a diversity of planetary compositions possibly ranging from bare rock to a significant volatile atmosphere.

The short lifespan of software puts a time limit on the reproducibility of computational research. To extend software longevity, guidelines and tools to preserve scientific workflows and analysis are helpful, but the challenge is to get researchers to use them.

Cassini measurements suggest hydrothermal activity on Enceladus that could support methanogenesis. Bayesian analysis of models simulating an abiotic or biotic ocean indicates the latter is more probable so long as abiogenesis is sufficiently likely to occur.
