📡 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.

A group of us visited the Dwingeloo radiotelescope on Sunday. I've often cycled down there to ride over the heath or sit near the radio telescope and eat my lunch, but not been on a guided tour before. I recommend it. You can currently book a tour on Sundays and Wednesdays in July and August.

Real discoveries were made here. This was once the largest radiotelescope in the world, a title which of course it has not held for many years.

But the telescope can now do more than it could in the 1950s and 60s because its capability is enhanced by modern software. This made it possible for the wonderful enthusiastic amateurs who now run the telescope to demonstrate things to us within five minutes which once took months for a group of scientists to work out.

" It is hailed as a global endeavour to explore the hidden universe – a powerful telescope comprising more than 130,000 antennae being built in outback Western Australia. But while the venture is being lauded as one of the most significant scientific endeavours of the 21st century, the Guardian can reveal that the organisation managing the funds of 16 member states has been rocked by allegations of financial misconduct."

The ‘cosmic clocks’ preparing SKAO for early science

Observations of pulsars – rapidly spinning dead stars – are helping the SKA Observatory to prepare for science operations.

The signal ⤵️ shows 100 pulses from the Vela pulsar and has been sonified 🔊

We had a great week full of science in Görlitz. Many thanks to @skao , DZA, and all the other organizers! 🙌

You can get a glimpse of the fantastic atmosphere at the event in our short video.

#skao #RadioAstronomy #Radioastronomie #science #wissenschaft #conference #konferenz #görlitz

🌟 From June 16 to 20, 2025, Görlitz will become the 𝐡𝐨𝐭𝐬𝐩𝐨𝐭 𝐨𝐟 𝐢𝐧𝐭𝐞𝐫𝐧𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐫𝐚𝐝𝐢𝐨 𝐚𝐬𝐭𝐫𝐨𝐧𝐨𝐦𝐲! 🌟

At the @skao Science Meeting, over 500 researchers from around the world will come together to advance the world’s largest radio telescope, the Square Kilometre Array Observatory.

Germany is strongly represented as a founding member through the MPIfR and the DZA. The conference will highlight exciting topics such as cosmology, galaxy evolution, gravitational waves, and the search for life beyond Earth.

👩‍🔬👨‍🔬 Over 200 scientific talks, international experts, and a public program featuring a lecture by Prof. Dr. Michael Kramer on June 17.

We are very much looking forward to the conference and a successful collaboration!

🥁 We start the day with great news:

"The first image from the international SKA Observatory’s telescope in Australia, SKA-Low, has been released today – a significant milestone in its quest to reveal an unparalleled view of our Universe."

LOOK!

These odd plots represent the first data from the SKA-low telescope working as an interferometer.

Data comes from two stations (each with 256 antennas) where the signal is correlated. That little kink is the radio galaxy Centaurus A.

SKA is starting to come online!

SKA-low features these odd-looking antennas that resemble Christmas trees. 256 of them sit in a ‘station’ which acts as a single unit. Once construction is complete (end of decade) there will be 512 stations separated by distance creating a large virtual telescope.

SKA-low is the Australian side of the project and will feature over 131,000 antennas to cover the low-frequency bands.

This will complement SKA-mid, located in South Africa which will have an interferometer made of dish antennas and cove a huge bandwidth up to 15 GHz.

This book has triggered some memories on the early involvement of Spain in the SKA development which I documented on LinkedIn, but I will write a thread here about them.

Great book (PDF & EPUB) if you have any interest in the SKA's early history. Really good job from Richard Schilizzi, Ron Ekers, Peter Dewdney, and Phil Crosby on compiling a lot of evidence on the journey to establish the SKA, with what went well, and not so well, with lots of detail and notes.

"A bit of me feels that the horse has bolted and we're in catch-up mode at this point."

But: "There's a social good element to what the satellite operators are doing and you've got to balance that against possible impacts to things like radio astronomy."

The first #MeerKAT+ antenna was today handed over in a festive ceremony in the Karoo region in South Africa. 🥳

This marks another important step towards the Square Kilometre Array Observatory (#SKAO), as the 14 antennas of the MeerKAT extension will be integrated into the SKAO in 2027.

What is a SKAMPI doing in the Karoo semi-desert in South Africa?

Unique scientific research! 👍

The SKA-MPIfR telescope (SKAMPI) is a prototype dish for the SKA-Mid telescope currently under construction in South Africa.

Take a look at the stunning results of the "First Light" observations of the Vela pulsar: https://www.mpifr-bonn.mpg.de/pressreleases/2024/3

This is the #SuperBowl that matters the most. Could we perhaps come up with the will and the funds to rebuild it? Seriously; if we are going to be shooting down "#UFOs" every few days; it makes a lot of sense to kickstart the work of #SETIInstitute before we inadvertently start an interstellar fight we can't finish.
