New paper day! In 'Near-future rocket launches could slow ozone recovery', we show that scaling up use of launch vehicles 🚀 has a point where the healing of the ozone layer is affected 🧪🛰️

BEHOLD the majesty of the Kiwi cheese scone. This scone isn't here for a fancy tea. This scone has come to rumble. This scone demands MORE butter. This scone has OPINIONS about jam. This scone is three square meals and elevenses. This scone has HEFT.
You do not eat this scone. You experience it.
You're looking at a large yellow gold beast, AKA a kiwi cheese scone, sitting on a white stoneware plate. It dominates the plate and the small bowl featuring two hefty triangles of butter next to it. If you were to lift this scone, you would feel its heft. This scone sees cheese and says give me more! You know that if you tapped the top of this scone it would make an ominous hollow sound that, if you know your cheese scones, promises a delicious crunchy top with a soft interior. Also on this table, admiring this scone is a yellow tea cup sitting on a blue saucer. A frankly inferior looking stainless steel teapot and milk jug containing just enough brew to wash down the scone. Elsewhere on the table is a comedic book from 1936 about Gardening and my notebook that I was using to jot spotted notes. It's brown covered and nondescript, unlike the scone of might. Which is easy to descript. It is majestic.

We tried in 2019 and got called 'cavemen'. There is only so much time and 3I doesn't observe itself

Just going to say that it is hurtful when a systematic study effort by the global small-body community, with many of the campaigns led by women, with results being pushed to free open-source arXiv & data repos for scicomm as quickly as possible, is described as lacking coordination/communication

I would anticipate something more official from ESA instruments in the near future. Be very surprised if anything is out yet though, downlink was barely finished

So today I celebrate the work of @carersinstemm.bsky.social who are calling for systemic changes to funding, policy & culture to support carers in STEM. Funders & employers must listen if they recognise and value the importance of a diverse workforce.👩‍🔬🧪

Read their report 👉 carersinstemm.co.uk 8/9🧵
A Carers Guide for Institutions
1
Ensure institutional expense policy allows for the reimbursement of care-related costs including dependant and co-carer travel expenses.
2
Update and align institutional financial reimbursement policy with funder T&C’s relating to care-giving costs.
3
Establish institutional policy and disseminate to line managers and expense approvers to avoid inconsistent implementation and support.
4
Provide flexible carers grants for all staff and students with minimal administrative burden to flexibly support ad-hoc care and do not mandate online attendance.
5
Consider the competing demands of meeting sustainability goals and the requirement to support carers (e.g. trains, flight times on weekends).
6
Decouple measures of research impact and esteem from travel opportunities with updated academic guidance.
7
Allow for family-friendly travel accommodation options including booking outside of approved institutional travel providers.
8
Provide a per-diem (a daily allowance) option for complex trips to reduce
administrative burden on carers.
9
When hosting an event, ensure risk assessments and insurance policy align to allow access to those under the age of 18.

"ESA plans to release imagery by next week. NASA will not be able to release any of its data, or even comment on it, until the U.S. federal government ends the shutdown."

All eyes on #3I/ATLAS ☄️

Our Mars Express & ExoMars Trace Gas Orbiter will observe the comet around its closest approach to Mars on 3 October 2025, when 3I/ATLAS will be around 30 million km from the red planet.

Stay tuned and follow esa.int/3IATLAS 🔭🧪
Infographic showing the path of comet 3I/ATLAS, the third known interstellar object to enter our Solar System. It displays the orbits of Earth, Mars and the Juice spacecraft around the Sun, along with key dates and events as comet 3I/ATLAS travels through the inner Solar System in 2025. Coloured and numbered dots mark important observation points by telescopes and spacecraft.

That'll be a lovely dataset. Sounds like you folks with @kwalsh4a.bsky.social have it covered for outbursts etc through perihelion passage then 🤩

Clouds are by far my favorite photographic subject. On Saturday September 27, 2025 a storm passed across the High Desert bringing thunder and rain. For a time cumulus clouds rolled over the region, some catching the sunlight and other closer shaded clouds being indirectly lit by them.
This photo shows brightly lit cumulus clouds in the background lighting up the edges of the nearer shaded clouds,

Comet 3I/Atlas is a fun challenge for PUNCH. We're very sensitive, though not a "telescope" (~2.5' resolution: basically naked-eye). At mag 12, the sky is *very* crowded. But we can see Atlas and SWAN in nearly-raw data. We're imaging at 4 minute cadence 24/7; FOV is 90° centered on the Sun. 🧪🔭🛰️☀️
A starfield from the PUNCH mission shows two comets:  SWAN and the interstellar comet Atlas.

Maori scholar, Makereti Papakura writing at her desk c.1910. The room is decorated with a mix of Maori & European mementoes whilst the rafters are painted with traditional kowhaiwhai patterns. Makereti will be awarded a posthumous degree in Oxford tomorrow, almost a century after she died in 1930.

Saturn, rising behind its largest moon Titan.

This scene is a composite of images taken by the Cassini spacecraft on 31 March 2005. At the time, Cassini was 7,000 km from Titan and 1.2 million km from Saturn.

In the foreground is Saturn's giant moon Titan, its hazy, peach-coloured atmosphere extending into space. Behind is Saturn itself, its upper hemisphere crossed by the shadows of its vast ring system.

"The power on campus is out. The buildings are all locked down and there's no access."

"There's a 4.56 billion year old asteroid fragment in my office that needs to be on an international flight tonight."

This trip was not starting smoothly 🤨

They are such a great wetland bird. Super successful at chick rearing too, often see them with 4 or so fledging, way more than mallards
