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 ...

It's so exciting to see the HARPS3 instrument coming together in real time at the Isaac Newton Telescope! Looking forward to the first light soon

I have had a few students go through this program and strongly recommend it!

This sounds like a really cool paper, definitely going on my reading list!

TFW you tick an item off your todo list and you realise it's over 5 years old...

Very happy to advertise a Postdoctoral Research Associate in Exoplanet Science position with me and Christian Schwab at Macquarie University in Sydney. We'll be working on applying machine learning & differentiable physics models to extremely precise radial velocity surveys.

The 2026 ESA Graduate Trainee positions are waiting for your applications! Step into a unique role where you’ll contribute to inspiring space missions and work alongside leading professionals from across Europe. Discover the available positions 👉 jobs.esa.int #ESArecruits 🔭 🧪

Great commentary on the recently announced budget cuts to physics and astronomy in the UK, by @chrislintott.bsky.social www.ox.ac.uk/news/2026-02...

We're recruiting international MRes and PhD students at Macquarie across stars & planets, galaxies, and instrumentation. Sign up here by February 8! In particular, I'm recruiting for exoplanet projects generally and have funding for RVs in particular. Submit your expressions of interest here!

Here's a fun piece of code I wrote to visualize the astrometric orbital elements. To run the visualization for yourself, check it out here: github.com/sblunt/show-... Black dashed is the line of nodes, and lighter purple indicates the part of the orbit that is behind the plane of the sky. Enjoy!

Anyone happen to know how I can query GAIA DR3 given ESA servers are down? 🔭 Interested in light curves specifically

That image just blows my mind

It was an absolute pleasure hosting you, @johannavos.bsky.social, and hearing about the exciting work going on in your group. What fantastic datasets. I'm looking forward to learning lots more about the variability of ~Jupiter-sized objects in the coming months/years!

I'm absolutely delighted to have been awarded the 2026 George Darwin Lecture by the RAS @royalastrosoc.bsky.social !

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

Are you a bachelor or master student anywhere in the world, and would like to come to us to work full-time on a supervised research project? Applications for the 2026 MPIA Summer Internship are open now!

⭐️✨🔭Please help us get the message out about the 7th annual international ASPIRE program at @api.uva.nl. This summer 2026 school provides astronomy research experience for talented MSc students from countries where opportunities to move into a PhD program are limited. Applications are due 17 Dec! ⭐️✨🔭

Interested in finding transiting planets at long periods, e.g. with the @platomissioncon.bsky.social? We just published a Research Note led by Geert Jan Talens, showing that such transits can be much longer or shorter than usually assumed iopscience.iop.org/article/10.3...

HARPS3 team back on site to start the installation!

We are hiring a new Assistant Professor in Astrophysics at Trinity College Dublin!! ☘ Job ad here: aas.org/jobregister/... Deadline: Jan 02 2026 Please share widely! 🪐🔭

Cambridge! We’re bringing a Universe of Music to you next Thursday. This show features shells, black holes, music, planets and more - do come if you can! www.junction.co.uk/events/linto...

It’s #ExoELT week! A week dedicated to discussing all things exoplanets and the ELT, @eso.org’s 39-m telescope coming online in 2029 😱 The size of this machine is just extraordinary. You can fit a whole VLT telescope on its Nasmyth platform 🤯

Hey London folks: come join me for this next week! It’s going to be a great night! wegottickets.com/event/676292

Our group's latest paper, led by @astroklein.bsky.social, applies Doppler Imaging (DI) to the Sun. Anyone who knows about DI will scream: "you can't do that! DI is for rapidly rotating stars!"...

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... 🔭🪐🧪

Stunning image!

It’s paper day 🎉!! If you are interested in seeing how supergranulation changes over a solar cycle in RVs give it a read! arxiv.org/abs/2506.23693

Many Oxoplanets members are at #EPRV6! Chat to them about the awesome work they have been doing!

Had a great time learning all about PLATO and the PLATO-ESP conference in Marseille this week!

The countdown is on to our National Astronomy Meeting this summer! We're very excited about the science that'll be shared at Durham University from 7-11 July. 🪐💫🔭 ☀️ Have you booked your place? If not, find out more about how to do so at: conference.astro.dur.ac.uk/event/7/page...

I wrote a research note about the recent publication of the MIRI/LRS spectrum of K2-18b. The authors had claimed the detection of potential signs of life. I find the data to be consistent with a flat line 🔭🧪

Oh wow, this is *such* a cool concept - a 'game' procedurally generated from Wikipedia, in which you can literally traverse all of human knowledge and walk down rabbit holes

What the fuck? @ox.ac.uk @oxfordphysics.bsky.social is heavily involved with Rubin-LSST, this is not okay, we are extremely supportive and proud of our LGBT+ colleagues here in Oxford.

Lovely to see this planet, first discovered in HARPS data a few years ago by my current colleague and team member Michael Cretignier, now confirmed by an international team led by @asmasca.bsky.social using VLT/ESPRESSO! www.ox.ac.uk/news/2025-01...

The Roman Coronagraph team is soliciting input on what to do with 2200 hours on the highest contrast coronagraph ever flown! There is no open-time program, so fill out this survey on the technology demonstration and science that you think would be most interesting! docs.google.com/forms/d/e/1F...

The Bell Burnell Graduate Scholarship Fund applications are open! This provides funding for current/prospective PhD students from underrepresented groups in #Physics ⚛️ & Astronomy 🔭 🧪Application deadline is 20th Jan 2025. FAQs: www.iop.org/about/suppor... #WomenInSTEM: www.iop.org/about/suppor...

Congratulations to Harrison! His paper concerning the atmospheres on lava planets has been accepted and published online today!

Congratulations to DPhil student Haochuan Yu (supervised by @airbornegrain.bsky.social) for the publication of his paper "A possible misaligned orbit for the young planet AU Mic c"! You can read it here: arxiv.org/abs/2411.16958

Describe yourself using 5 things that are probably in your purse/backpack at any given moment: 1. random bits of lego 2. todo list on tissue paper, written at 3am to banish insomnia (didn't work), makes no sense at all. 3. bike lights 4. a novel 5. snack pilfered from work for my kids

It's paper day! Haochuan Yu, an outstanding PhD student working with me, has developed a new Gaussian process model for activity induced variations in time-series of stellar line profiles, that accounts for both the time- and velocity-domain correlations: arxiv.org/abs/2410.12698

Saddened beyond belief by the sudden passing of our boss Ian Shipsey. Ian was remarkable, in his science & as a passionate unselfish force for good, who made a huge contribution to Oxford Physics, the upcoming Vera Rubin & much else 🧪 🛰️ 🔭 www.mpls.ox.ac.uk/latest/news/...

Big (but not heavy) results from the Young Worlds Lab. JWST transmission spectrum of the 17-myr planet HIP67522b reveals it's only 10-15 Earth masses despite being similar in radius to Jupiter. This gives it a density lower than any other known planet. more below arxiv.org/abs/2409.16355 🧪🔭🪐⚛️

Cool stuff!

Earlier this year I had the pleasure of giving a #TEDxTalk about my passion for #exoplanets. The talk is now online - I hope you enjoy watching it. My thanks to the all-student team at TEDxWarwick, who made it all happen! 🔭🧪

Optimist: the cup is half full Pessimist: the cup is half empty Me (clumsiest person in the multiverse): sorry I knocked the cup over so we'll never know how full it was
