The complete #ag2025goerlitz conference poster "20-FOLD RESOLUTION IMPROVEMENT IN RADIOASTRONOMICAL SINGLE-DISH IMAGE SCANNING" which raised some eyebrows in Görlitz - and comes with the video https://www.youtube.com/watch?v=Qc1C4JNTGXk - is available at https://ag2025.astronomische-gesellschaft.de/posters/Ebersberger_Johannes_41.pdf (there is also an article in https://www.naa.net/rb/rb_2025-3.php but apparently only in print while http://radioastronomie-leicht-gemacht.de covers some basics). #RadioAstronomy #ImageProcessing

" 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."

I built a more accurate Galactic GPS for aliens to find us!
In the 1970s, the Pioneer and Voyager spacecraft were launched into deep space - each carrying a message from Earth in the form of plaques and golden records. These included a now-famous diagram: the pulsar map, originally proposed by Carl Sagan, Linda Salzman Sagan, and Frank Drake.
It uses the positions and spin periods of 14 pulsars to show where we are in the galaxy, effectively a cosmic return address.
But there’s a catch: the original map used canonical pulsars, which we now know can glitch and show timing instabilities. Back then, millisecond pulsars hadn’t yet been discovered (they came in the early '80s), so they weren’t included.
As someone studying millisecond pulsars and their long-term timing stability for my PhD, I decided to write some code to rebuild this iconic map - with a little upgrade.
Enter: the Millisecond Pulsar Map.
This version features:
- A top-down view of the Galaxy, with a central measuring bar showing our distance (8 kiloparsecs) from the Galactic Centre.
- Radial lines showing the distance to each millisecond pulsar. These can be measured against the central measuring bar to work out this distance
- Binary encodings for each pulsar's spin period and spin-down rate. These parameters will remain much more stable over the long term.
- A decoding scale to interpret the binary inscriptions.With 40+ years of high-precision timing data, millisecond pulsars are far more stable than their slower cousins - making them ideal for building a map that could stand the test of cosmic time.
This also highlights how millisecond pulsars could be used as an intergalactic GPS network (because these stable pulsars are like cosmic clocks distributed across the sky). This might be an application for future spacecraft to navigate around the Solar System. Have a read of this article for how we are already building this technology now: https://www.spaceaustralia.com/feature/breaking-free-shackles-terrestrial-time
So, if some distant civilisation stumbles upon this new pulsar map ... well, they’ll know exactly where to find us.
The question is: do we really want to leave our full galactic home address out there?!

The “Eye of Sauron” spotted in deep space
👁️ Okay, so the plasma jet in the blazar PKS 1424+240 isn't on a tower in Mordor, and it's not the fire-rimmed eye of a powerful tyrant. But if you don't think of Sauron's eye when you see the image released today, throw the first ring.
📡 Behind this deep image of the jet at unparalleled resolution are 15 years of ultra-precise radio observations with the Very Long Baseline Array (VLBA) and an international research team.

Das „Auge von Sauron“ im Weltraum entdeckt!
👁️ Zugegeben, der Plasmastrahl im Blazar PKS 1424+240 befindet ich nicht auf einem Turm in Mordor und es handelt sich auch nicht um ein von Feuer umrandetes Sehorgan eines mächtigen Herrschers. Doch wer bei dem heute veröffentlichten Bild nicht an Saurons Auge denken muss, der werfe den ersten Ring.
📡 Hinter diesem detaillierten Bild des Jets mit der bislang besten Auflösung stecken 15 Jahre ultrapräziser Radiobeobachtungen mit dem Very Long Baseline Array (VLBA) und ein internationales Forschungsteam.

The South African MeerKAT telescope is the precursor of SKA-MID. The expanded MeerKAT+ array — including more than a dozen additional SKA antennas and receivers — is part of a project funded in partnership by SARAO (@ska_africa), the Max Planck Society (@maxplanckgesellschaft), and INAF.
