![Maps of average lensing parameters of simulated microlensing events due to different BFFPs over the 2D space log10[s(AU)]−log10[Mtot(M⊕)]. Here, Fi and Fw are fractions of simulated microlensing events due to BFFPs with intermediate and wide caustic topologies, respectively. ρ? shows the source radius projected on the lens plane and normalized to the Einstein radius, Lc is a length scale for caustic curves, ∆c represents the caustic area, τ is a time scale for microlensing events due to BFFPs, and P is the orbital period of binary lenses. -- Monthly Notices of the Royal Astronomical Society](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/On-the-Detection-of-Binary-Free-Floating-Planets.png?resize=1200%2C720&ssl=1)
The recent discovery of 40 binary Jupiter-mass free-floating planets in the Trapezium cluster by the James Webb Space Telescope (Pearson & McCaughrean 2023) has opened new windows and questions in […]

First Demonstration of Kernel Phase Interferometry on JWST/MIRI: Prospects for Future Planet Searches Around Post Main Sequence Stars
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.
