A new model demonstrates how the formation of annular structures in a protoplanetary disk can later produce planetary systems that reproduce both the orbital architecture and meteoritic isotope trends observed in our Solar System.
A new model for the origin of the Solar System proposes planet building blocks formed fast from material that was transported outwards to cooler regions. It claims to be consistent with the properties of ancient meteorites.
The first robotically obtained samples of a carbonaceous asteroid have been safely returned to Earth. A non-destructive first-look analysis shows that asteroid Ryugu may be a CI chondrite with interesting variations.
Unlocking the internal secrets of a β Cephei star with a state-of-the-art polarimeter may open up a greater understanding of whether a massive star eventually explodes in a supernova or collapses directly to a black hole.
The limits on late accretion and its associated water delivery to potential habitable planets are derived by examining the dynamical stability of the resonance-bound TRAPPIST-1 system.
A simulated hybrid emission model to mimic the morphology of the jet launching region of M87 reproduces the observed shape of the innermost jet and favours a high spin of the central black hole.
A fluorine abundance measurement in a high-redshift galaxy demonstrates an early, quick rise in chemical enrichment of the Universe. The presence of fluorine at this early epoch also reveals a unique early source of the element.
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.
