A multiwavelength study reveals a vertically extended inner disk in a black hole X-ray binary at unexpectedly low luminosities, reshaping its emission and shielding the outer disk, with implications for its physical and observational properties.

UV spectra of six similar galaxies show that stronger, faster, multiphase outflows accompany lower escape of ionizing radiation. Thus Lyman continuum escape may peak before strong galactic winds develop and then decline as the wind-column density grows.

A new method of extracting atmospheric variations around the limb of a hot Jupiter using transmission mapping of JWST data finds a transition between the equator and pole of WASP-17 b. The authors measure a 650 K temperature difference between the morning and evening and find H2O and CO2 limb abundances consistent with circulation models.

Archival data show a pronounced bimodality in the architectures of known multi-planet systems that can be traced back to the interplay of host star properties and planet formation histories, which shaped the post-formation dynamical stability of the systems.

N-body simulations decode the chemo-kinematic signatures of the Sagittarius stream, reproducing their vertical metallicity gradient. The findings reveal that the stream originated from a disk with a ∧-like metallicity profile.

For decades, the NASA Astrophysics Data System (ADS) has been the foundational digital library for astronomy. As ADS now becomes the Science Explorer (SciX), the team prioritizes preserving this trusted experience while increasing their support for space and Earth sciences more broadly, without diluting its commitment to astrophysics.

After more than 33 years, NASA’s Astrophysics Data System will close its virtual doors in November 2026 and be replaced by its much-expanded successor, Science Explorer. While the core functionality and astrophysics database will remain the same, SciX will extend its relevance to a broader range of scientists.

In Chile, the Center for Astrophysics and Associated Technologies has been working towards turning scientific investment into economic success for two decades, through the transfer of technology and techniques from astrophysics to industry. Many successful projects provide tangible examples of the real-world benefits of astronomy.
