Kernel phase interferometry (KPI) is a post-processing technique that treats a conventional telescope as an interferometer by accurately modeling a telescope pupil as an array of virtual subapertures.

Deuterated Water Ice On The Satellites Of Saturn
The deuterium to hydrogen ratio in water ice in a planetary body carries important information on the history of water processing and delivery in the protostellar nebula.
![Line profiles of ionized emission from the outflow in the nuclear region of W2246- 0526, marked with a red circle in the inserted figure showing the extended Hα emission in the W2246-0526 system, adapted from Vayner et al 2025 (40). Extremely broad and blueshifted emission is detected in [O III], Hα and Hβ, with maximum velocities of -13,400 km s−1 (V02), where 0 km s−1 is systemic. The detection of [O III] indicates that this emission originates beyond the broad-line region of the quasar. We also overlay the CIV λλ 1548 A, 1550 A emission line spectrum from rest-frame UV observations taken by the MUSE instrument, showing a similar profile to the optical lines. The solid black line shows the average velocity of the profile (V50). The red line shows the velocity of the dusty outflow traced through aromatic and aliphatic hydrocarbon absorption. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/Probing-The-Physics-Of-Dusty-Outflows.png?resize=1200%2C719&ssl=1)

Probing The Physics Of Dusty Outflows Through Complex Organic Molecules In The Early Universe
Galaxy-scale outflows are of critical importance for galaxy formation and evolution. Dust grains are the main sites for the formation of molecules needed for star formation but are also important […]

Sub-Neptune Exoplanet K2-18b Does Not Meet the Standards Of Evidence For Life
K2-18b, a temperate sub-Neptune, has garnered significant attention due to claims of possible biosignatures in its atmosphere. Low-confidence detections of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) have sparked considerable […]

Optical Design Pathways to Fluidic Space-Assembled Reflectors & Dual-Configuration Spectrographs for Characterizing Exo-Earths
In-space assembly of optical reflectors can solve light-gathering aperture scaling, which currently limits space-borne optical telescopes. Our compass reduces the top-level optical design trade to three types of avenues—a fluidic […]
