🔭 Really enjoyed stumbling over this paper, and in particular the sass of its title: Saturns Are Not Large Neptunes! Not every day we get a new flavour of #exoplanets — will definitely be using ”Saturnian” from now on 😊 cool work by @niamhk12.bsky.social and others! ✨🪐 arxiv.org/abs/2609.170...

Today we had the pleasure of hosting Francis Zong Lang from the University of Bern who gave a seminar about detecting terrestrial sized planets around M stars and even brown dwarfs! He also talked about how he is using his astrophysics skills to help inspire communities in Nigeria and Cameroon!

Here comes the S̶u̶n̶ Moon 🌑 On 12 August, a total solar eclipse was visible across parts of Europe, while much of the continent experienced a partial eclipse. From space, MTG-I1 recorded the Moon’s shadow moving across Earth: www.esa.int/ESA_Multimed... 📹ESA/Eumetsat

The sun came out! Such a beautiful location-feeling so lucky that I get to travel to see things like this!

Made it to Spain for the eclipse (despite the thesis deadline) but the clouds don’t seem to be in my favour. Hoping that they clear for like they did in Dallas in 2024! ☀️⛅️

This is the highest-resolution view of the surface of the Sun. Ever. Taken by the NSF's Daniel K. Inouye Solar Telescope, features as small as 19 km across can be resolved. The wispy things are magnetic field boundaries formed by Kelvin-Helmholtz instabilities. The island of Ireland for scale.

It's not just radio astronomy though. Also "not prioritised for further funding" is HARPS3 - the brand new ultra-stable high-resolution spectrograph (+ polarimeter) for the Isaac Newton Telescope in La Palma.

Short-sighted, stupid cuts to the UKRI budget include shutting down Jodrell Bank, the icon of British astronomy. (Many other cuts too, including 20% to our brand new @vrubinobs.bsky.social). Interesting politically to shut down a major facility in...um..Manchester 🔭 www.bbc.co.uk/news/article...

Jodrell Bank's Lovell telescope faces axe in science cuts, BBC understands

Astronomers warn it would tear the heart out of UK science, and leave a generation untrained.

Congratulations to Niamh O’Sullivan (@niamhk12.bsky.social) on her talk "The Search for Supergranulation across Spectral Types" at #Exo6!

Made it to #exo6 only one day late and with a partially dislocated wrist! Looking forward to a great rest of the week - it can only get better!!

A full-on week, fighting to #SaveUKAstronomy & PPAN from 30% funding cuts. There were highs (👇hanging out with fab-folk) & lows (@ukri.org trying to erase history in old Council minutes) but the amazing support & ❤️ from the wonderful wide astro-community makes it all worth it. Onwards and upwards 💪🔭

Cool Stars talk is done! Was really fun to talk about starting to investigate supergranulation in the wavelength domain! (Even if a plenary talk was a little nerve wracking!!)

"Someone, somewhere, has taken the decision to defund astrophysics research in the UK, but no-one seems quite sure who that was, or why." The latest on the impact of the catastrophic funding cuts to UK astrophysics, by me, in @natastron.nature.com 👩‍🔬🧪🔭 ✒️ www.nature.com/articles/s41...

Officially finished my pre-doctoral fellowship at the CCA in New York investigating supergranulation in the wavelength domain! Thanks so much to everyone who made this such a wonderful experience, in particular my supervisors! Next, back to Oxford to write a thesis!

Conference season has started! Excited to be finishing off my time at the Flatiron Institute by sharing my research at the New York Area Exoplanets Meeting!

Did you know that stars have fingerprints? To help you search for them (aka to view how different types of stars have characteristically different spectra in the Gaia RVS region) I created this visualization below, best viewed on desktop! zoehackshaw.github.io/kiel_explore... Happy exploring! 🧪🔭

Before installing the detector it's essential to take some time out and see the gorgeous spectrum with your own eyes. It's impossible to capture what the eye sees but this photo gives you an idea ...

Successful Echelle installation 🎉 The heart of HARPS3 is looking amazing 😍

I was part of this program a few years ago and I can’t recommend it enough!

The future of UK Astronomy & Particle Physics is at risk from proposed 30% funding cuts that, if implemented, will be "genuinely catastrophic". Great to see this detailed BBC report on the issue by @pallabg.bsky.social 🔭🧪⚛️ #STFCcuts #SaveUKAstronomy 🗞️: www.bbc.co.uk/news/article...

This week we are hosting the @terrahunting.bsky.social science team in Oxford. Terra Hunting will use HARPS3 which is right now being installed on the Isaac Newton Telescope in La Palma to search for nearby Earth analogues. Exciting times! @oxfordphysics.bsky.social @oxoplanets.bsky.social

My dad is moving which means going through all my books stored at his- my Astro book collections is slightly insane it turns out. But more importantly, I found the book that started the space obsession for me! 🔭⭐️🪐

Big congrats to Jennifer Burt, Xavier Dumusque, and Sam Halverson on finishing their epic (instant classic) Annual Reviews of Astronomy & Astrophysics article "Precise Radial Velocities"! arxiv.org/abs/2511.01954 contains some great new graphics for talks on #exoplanets #EPRV #DopplerSpectroscopy

HARPS3 has definitely arrived at the INT (and I was only slightly excited to see it!) @terrahunting.bsky.social

I’ve made it to La Palma where I’ll be spending the next week observing with the TNG! Here are some mandatory photos of the observatory 🔭🌟💫

It’s happening!! Can’t believe I arrived in La Palma the same day!

A dawn delivery to the Isaac Newton Telescope this morning ... HARPS3 shipping containers arrive!!!

Great talk by @niamhk12.bsky.social on her talk at the Oxford Astrophysics Early Career Showcase! Teaching us all about supergranulation and the need to understand it in order to detect Earth twins!

The official number of exoplanets has surpassed 6,000! And you can access data on all 6,007 of them right here at IPAC 📈 🪐 Watch the video & read all about the center of the exoplanet universe (also known as NExScI!) here: www.ipac.caltech.edu/news/the-nas...

So excited for this!!!

Today HARPS3 is leaving the nest and migrating south!

Very excited to share that my new paper has been accepted for publication in MNRAS! We are applying Doppler Imaging to model the activity signals from the HARPS-N Sun-as-a-star spectra! We show that injected planets can be retrieved with great accuracy! ui.adsabs.harvard.edu/abs/2025MNRA... 🔭🪐🧪
