With the press release out, I'm delighted to share our work reporting the discovery of a 3rd planet in the beta Pictoris system! Say hello to beta Pic d - a gas giant with 2.4 times the mass of Jupiter that takes 91 years to orbit its host star, far longer than the 2 known planets in the system 🪐🔭

. @astrokiwi.bsky.social totally rocking a talk on 3I/ATLAS and ISOs more generally. Message: “The galaxy is primarily* composed of ISOs** *by number, to first order, cf. 10^26 **and their origin systems, and some perturbers, and a useful potential”

Our new @solarstormwatch citizen science project launched today! Can you spare time to help us identify times when the skies in the Arctic are clear? You will see beautiful #aurora and will help us to improve our #spaceweather research. www.zooniverse.org/projects/lep...

Clear Skies - Kiruna | Zooniverse - People-powered researchCan you tell us when the skies are clear? You may even see an aurora!www.zooniverse.org

Enjoying watching this epic @cosmicshambles.com documentary about music: youtu.be/quj8JVU-usw The first episode features me, @chrislintott.bsky.social, and @helenczerski.bsky.social talking about music physics!

A quick crowdsourcing exercise. @royalastrosoc.bsky.social is looking for copyright free images we can use for promoting the eclipse on 12 August (a deep partial in the UK) to the press and public. Can anyone help? Diagrams and photos of past events all good. We'll obviously credit contributors.

The start of a new survey of the Universe? That deserves a new view of the cosmos 🌌 Meet the Ocean of Stars, NSF–DOE Rubin Observatory's newest wide-field image. 🔭🧪 🔗: rubinobservatory.org/gallery/imag...

Zooniverse has reached an extraordinary milestone: 1 BILLION classifications contributed by volunteers! Want to learn how 1 billion classifications have made a real-world impact? Read our blog post and learn why we’re excited for what’s next: blog.zooniverse.org/2026/06/29/o...

I hate that this — urgent pleas to save prestigious departments from drastic cuts — is becoming a regular occurrence. A program like this takes decades to build and a few strokes of a pen to destroy.

Live meteorological data from the roof of @oxfordphysics.bsky.social has been a very useful site this past week - really captures the brutal overnight heat, and particularly this morning where 28˚C already by 9am (times on fig are GMT) eodg.atm.ox.ac.uk/eodg/weather...

Whoa! Simultaneous papers announcing the discovery of a new directly imaged planet - beta Pictoris d!!! arxiv.org/pdf/2606.23801 arxiv.org/pdf/2606.23789 It's just so BIG. I can't believe it's just so ROUND, it's like OUT THERE. 🪐 (Courtesy of my kids who have just discovered Sir Mix-A-Lot)

the media and voter messaging should be this: the current government and the government in waiting do not want your children to be able to go to university, they will not support people in the UK to do original research, they do not care about job losses in one of the largest sectors in the economy

Journalism is in crisis—including science and environmental journalism. The industry is in really rough shape, and this blow makes matters worse.
