Congrats @astrojake.bsky.social, can’t wait to work on this amazing program! Eclipses for the win 🌟🪐

So fun to see our work on #exoplanet WASP-127 b, led by the incredible Lisa Nortmann, as one of the "Top 10 Breakthroughs" of 2025 according to @physicsworld.bsky.social! 🔭🧪

Check it out below ⬇️ including a BUNCH more cool things I had no idea happened this year?!

HD 189733b eclipse maps, with flux profiles shown above. The cross and dashed line mark the location of the substellar point, whilst the star and dash-dotted line mark the location of the hotspot. Left: Simulated version of the JWST MIRI/LRS map, derived from two eclipses (M. Lally et al. 2025). Middle: Equivalent Ariel AIRS Ch1 map, also derived from two eclipse observations. Right: Difference map (JWST–Ariel). The flat structure shows that we recover consistent thermal structures between the instruments, although with a slightly shallower day–night gradient for the latter as a consequence of its smaller bandwidth (see the text). The overlap of the differenced hotspot with the substellar point shows that we accurately and precisely recover this key parameter.

It was great getting to share these exciting results as part of the BOWIE+ seminar series. Ariel has the potential to revolutionise our 3D understanding of exoplanet atmospheres, with a phase curve survey of ~100 targets within its reach. Let’s push to make it happen!

New paper alert 🔔 If you like eclipse mapping and are excited for the future opportunities that Ariel will provide, then check it out!

(Bonus: writing an eclipse mapping proposal? We've ranked all the best eclipse mapping targets for both Ariel and JWST!)

Stay tuned for future releases! 👀 (3/3)

This is only the first instalment in a series of work on this planet, wherein the DREAMS team aims to perform one of the most comprehensive atmospheric characterisations of any exoplanet to date, using data from a multitude of @NASAWebb instruments. ⭐️🪐🌈🔭 (2/3)

Check out this awesome work from the JWST-TST DREAMS team! Using a combination of @NASAHubble and @NASAWebb MIRI data, we made the first characterisation of a cloud species in a transiting exoplanet atmosphere: quartz clouds in the atmosphere of WASP-17b! 💨☁️🪐✨(1/3)

Excited to share the 1st direct evidence of quartz clouds in the atmosphere of a transiting #exoplanet! With #JWST MIRI we found nanoparticles of quartz, SiO2, causing a spike in the planet's spectrum at 8.6 micron unveiling the Oxygen locked in the clouds
