Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months.

Andrew delves into technosignatures and a study which looked at whether nearby extraterrestrial civilisations could detect our current levels of radio leakage, and exactly what they might be able to learn.

Hannah condenses the most recent JWST exoplanet paper, on the nearby transiting super-Earth GJ486b. The beautiful spectra from JWST appear to show hints of water vapour, but is it in the planetary atmosphere or the activity on the surface of the star?

And finally, Hugh covers a trio of papers which all used a combination of Hipparcos & Gaia astrometry as well as high-contrast imaging from some of the world’s largest telescopes to confirm a new giant planet orbiting the young star AF Lep.
