A leading Irish astrophysicist will take centre stage next month in a public lecture hosted by Astronomy Ireland, offering a rare glimpse into the cutting-edge science of exoplanet atmospheres.

Dr Cathal Maguire, a postdoctoral researcher at the University of Bristol, will deliver the talk via Zoom on November 10 at 7pm. Tickets are priced between €5 and €10.

The lecture, titled “Exoplanet Atmospheres,” will explore how scientists are using powerful new tools like the James Webb Space Telescope to analyse the skies of planets orbiting distant stars. With thousands of exoplanets now confirmed, researchers are shifting focus from discovery to detailed characterisation, using spectroscopy to decode the chemical fingerprints of alien atmospheres.

Dr Maguire, who earned his PhD from Trinity College Dublin in 2024, specialises in high-resolution transmission spectroscopy and advanced data modelling. His work has focused on ultra-hot Jupiters, gas giants with extreme temperatures that offer a natural laboratory for testing theories of planetary formation and dynamics.

The talk promises to unpack how atmospheric analysis can reveal not only the composition and climate of these distant worlds but also their potential to support life. Organisers say the event is aimed at a general audience and will include time for questions from the public.

Astronomy Ireland, the country’s largest astronomy group, regularly hosts lectures by leading scientists to promote public engagement with space science.
