I'm exploring a DIY instrument to measure infrasound (<20 Hz) and low-frequency emissions near data centers, to complement a Class 2 sound-level meter.

Thinking ESP32 + differential pressure sensor + wind filtering + raw spectral analysis. Interested in comparing designs, calibration methods, and field measurements. Anyone else working on this or interested in collaborating?

🔭 Citizen science in Czechia: on the morning of 8 Sep 2026, asteroid (712) Boliviana will occult star TYC 1348-00100-1 (10.9 mag) in Gemini for up to 3.5 s. The 132 km wide shadow path crosses the country from Šumava (02:38:29 UT) to the Beskydy mountains, 29° above the eastern horizon. Every timing — positive or negative — refines the asteroid's shape and orbit. (7 Sep 2026)

Lost Bones #7 is now published!
In 1929, a nearly ten-pound mammoth molar was discovered west of New Ulm, Minnesota. It was donated to the University of Minnesota—and then effectively disappeared into nearly a century of museum transfers.

A Mighty Beast follows my seven-year search for the tooth, from a single entry in a 1945 paleontological survey to its eventual rediscovery in a museum collection.

🪐 A giant ten-sided jet stream wave encircles Saturn's south pole. Amateur astronomers spotted the first hints in images shared through the open PVOL archive run by the University of the Basque Country; Hubble's OPAL programme then traced it back to 2023. A neat case of worldwide observer data leading to a discovery. ESA/Hubble, 2 Sep 2026.

📡 Images from the Radio Galaxy Zoo citizen science project were used to pretrain very small vision models (~6M parameters) with LeJEPA. A University of Geneva team shows that self-supervised learning directly on radio astronomy data matches far larger models at radio galaxy morphology classification — cheaper and more scalable. Preprint, 31 Aug 2026.

For #FossilFriday—dinosaurs headline the Minnesota State Fair, but an Ice Age predator is also on display!

These 26,900-year-old Homotherium serum fossils from Tyson Spring Cave include a skullcap, shoulder blade and foreleg. Found beginning in 2008, they provided the first record of this scimitar-toothed cat in Minnesota and the Great Lakes region.

See them through Sept. 7!

Why did 1,000 world citizens bury their underpants?

Study: Land use is the biggest factor in determining decomposition rates of organic cotton underpants.

Jennifer Ouellette – Aug 27, 2026

Excerpt: "A thousand people voluntarily buried their cotton underpants for two months—not to keep the Underpants Gnomes from stealing them, but as part of a citizen science project to map out soil health in 25 countries around the world. The results of this unique experiment were reported in a new paper published in the journal #PlantsPeoplePlanet.

" 'Our results show that how soil is managed can significantly affect both soil life and soil quality,' said co-author Marcel van der Heijden, an #agroecologist at the University of Zurich. 'Healthy, biologically active soil is crucial for fertility, nutrient cycling and many other #ecosystem services.'

" #SoilHealth is critical for #agriculture and, by extension, #FoodSecurity, not to mention a healthy #GlobalEcosystem, but it has been declining worldwide, per the authors. One key indicator of soil health is #decomposition rates of complex organic matter, breaking down stuff like leaves, wood, even cadavers into simpler organic and inorganic compounds, releasing C02 and nutrients in the process. There have been relatively few large-scale national decomposition studies involving different land use types, although smaller studies have shown that how humans use a site can significantly affect the soil’s biological diversity.

"Commercially available teabags are a common material used to measure decomposition rates, known as the #TeabagIndex ( #TBI ). However, Van der Heijden and colleagues felt the teabag index could be improved upon, given that it requires careful handling and specific tools, like a fine-scale balance. They opted for a more playful approach to illustrate soil composition.

"Prior research had shown that cotton strips could also be used to assess decomposition, so why not engage in a bit of #CitizenScience and ask volunteers to bury cotton underpants for a couple of months, then dig them up and record the results? That’s exactly what the authors did in a national project they dubbed 'Proof by Underpants.' "

🔭 NASA's Nancy Grace Roman Space Telescope has launched, and Zooniverse is getting ready for its data. Galaxy Zoo is building projects on galaxy shapes and spectra; Planet Hunters is exploring how Roman data could feed exoplanet searches. First science data are expected in 2027 — with new tasks for volunteers.

🔭 Open call for amateur astronomers: the ER UMa-type dwarf nova Gaia24aeg is in superoutburst.

A Kyiv–Wrocław–Warsaw team observed it for 3.4 hours on 9 Aug with a 0.7 m telescope and measured superhumps with a period of 0.077 d (~111 min) and an amplitude of 0.15 mag. You can upload your own photometry to BHTOM, the EU-funded open-source platform that processes it automatically.

Give your time to Nepal.

Analyse images from the Nepal floods to assist aid workers.

At the moment they're out of images to process but there will be more to do on Wednesday.

"Hello Zooniverse Planetary Response Network projects community,

To get started right away, click here: https://www.zooniverse.org/projects/alicemead/planetary-response-network-nepal-flash-flooding-2026/classify/workflow/32649

On 26 August 2026, a major flash flood struck Rasuwa District in northern Nepal, causing severe damage to local infrastructure and roads. Rescue and recovery groups on the ground urgently need accurate maps so they can get help where it's needed most.

Currently, aid agencies in the Nepal are working to get support to those who need it the most. We are providing the data to the International Charter of Space and Major Disasters, who will use it to inform humanitarian organisations on the ground.

This project aims to identify regions of flooding and road blockages in the affected regions of Nepal. You will be shown before and after images, and asked to detect signs of these attributes. The images for this project have been provided to us by Planet Labs, using 3-metre resolution data.

When classifying, please just do your best, and remember that we ask multiple people to examine each image, and we will gather consensus from the crowd. Even if you are uncertain, your best judgment is very valuable!

We need lots of support on the project to classify the data as soon as we can, to ensure data reaches humanitarian organisations as soon as possible. If you can help by making classifications, please click https://www.zooniverse.org/projects/alicemead/planetary-response-network-nepal-flash-flooding-2026/classify/workflow/32649.

As always, please remember to take breaks whenever you need or want to. If you are in distress and need or want support, here is a list of international mental health support hotlines and international crisis support hotlines so you can get support wherever you are in the world. https://findahelpline.com/

Thank you,
The Planetary Response Network team"
