Determination of the mass distribution of the first stars from the 21-cm signal - Nature Astronomy
Next-generation radio telescopes, such as the Square Kilometre Array, will be able to reveal the mass distribution of the first stars in the Universe by detecting their impact on a faint radio signal of hydrogen atoms from Cosmic Dawn.

Co-precession of a curved jet and compact accretion disk in M87 - Nature Astronomy
M87’s jet is precessing with a relatively short 11-year period and seems to be curved in the vicinity of the black hole, rather than being strictly collimated. This indicates the presence of a compact accretion disk and points to gaps in our understanding of jet dynamics.

Fermi detection of gamma-ray emission from the hot coronae of radio-quiet active galactic nuclei - Nature Astronomy
The Fermi-LAT Collaboration reports a significant γ-ray detection (5.2σ) from the coronae of radio-quiet active galactic nuclei, revealing compact (~10 gravitational radii) and extended (~2.7 × 106 gravitational radii) corona regions, challenging existing models.

Deep chemical weathering on ancient Mars landscapes driven by erosional and climatic patterns - Nature Astronomy
New findings reveal how terrain influenced Mars’s early surface evolution, allowing regions of stable chemical weathering to develop and permanently trap water and minerals, weakening Mars’s climate feedback and limiting long-term hydrological activity.

A gas-rich cosmic web revealed by the partitioning of the missing baryons - Nature Astronomy
Using a large cosmological sample of FRBs, Connor et al. have located many of the Universe’s unseen baryons, finding that most reside in the diffuse intergalactic medium, not galaxies—confirming the strong astrophysical feedback seen in simulations.

Earth-mass planets with He atmospheres in the habitable zone of Sun-like stars - Nature Astronomy
Simulations of long-term atmospheric evolution show that rocky planets with Earth-like masses in the classical habitable zone of Sun-like stars can retain thick He-dominated primordial atmospheres.

No certainty of a Milky Way–Andromeda collision - Nature Astronomy
It is widely believed that the Milky Way is set to collide with Andromeda, its nearest neighbour. New calculations using data from Hubble and Gaia that account for the effects of other galaxies show an almost 50% chance of our Galaxy avoiding this fate.

Observations of fine coronal structures with high-order solar adaptive optics - Nature Astronomy
High-resolution observations of fine structure in the Sun’s corona hint at plasma features on the order of 10 km. A new adaptive optics system, Cona, lifts the veil of atmospheric blur over a fast-moving, twisted plasma stream as it becomes unstable.

Very-wide-orbit planets from dynamical instabilities during the stellar birth cluster phase - Nature Astronomy
Giant planets on wide, eccentric orbits—like the putative Planet Nine—may form from dynamical planetary instabilities when stars are embedded in their natal stellar clusters. Simulations suggest a 1–5% chance of such planets forming in exoplanetary systems and up to 40% in the Solar System.
