Via @dr.starkid on Instagram:

Imperfection is fundamental to the universe.

The discovery that planets didn’t orbit in perfect circles threw a huge wrench into the idea that the universe was the result of some perfect “watchmaker” creator that put everything into to perfect circular orbits.

In fact, all interesting phenomena come as a result of chronic imperfection in the universe

First confirmed sighting of explosive burst on nearby star
"
"Astronomers using the European Space Agency’s XMM-Newton space observatory and the LOFAR telescope have definitively spotted an explosive burst of material thrown out into space by another star – a burst powerful enough to strip away the atmosphere of any unlucky planet in its path."

ASTRON: Exoplanet entfacht stellares Feuerwerk.
Astronom*innen haben beobachtet, wie ein Planet Stürme auf seinem Mutterstern auslöste – eine Entdeckung, die unser Verständnis davon, wie Planeten und Sterne miteinander interagieren und sich gemeinsam entwickeln, grundlegend verändern könnte. Diese Ergebnisse wurden heute in der Fachzeitschrift Nature veröffentlicht. Pressemitteilung #ASTRON.

Als we zijn uitgegiecheld over dat innovatie in Europa zich bezig houdt met het vastzetten van frisdrank-dopjes en we uitgebriest zijn over dat Nederland met z’n “stikstof-principes” en rechters die handhaven op een leefbaar land ipv groei en innovatie stimuleren…

Hier weer 1 van de vele juweeltjes voor als je weer in een “Europa reguleert alleen maar we zijn verloren” gesprek verzeild bent geraakt.

Using the Westerbork radio telescope, astronomers have discovered two dozen of the unexplained Fast Radio Bursts and discovered their origins!

Always nice to see great science made with an instrument you helped up build.

"Using the radio telescope at Westerbork, The Netherlands, astronomers have discovered two dozen of the unexplained Fast Radio Bursts. After zooming in on the signal of the distant bursts, the astronomers found a striking similarity to the radio flashes emitted by nearby, known neutron stars."

Sunday #WristCheck. Today's #watch of choice is my #seiko #Astron. Broke my typical rules about getting this watch when I spotted it. Even for a large watch it's pretty light because of the #titanium. Love the GPS time-sync.

R5 adjustment pot has to be bad, changing it does nothing, so it's got no connection to the wiper. Deoxit or Triflow sometimes removes any crud and gives it contact. Or, 1K pots probably cost 2 cents anyway. #repair #hamradio #Astron

Astron power supply almost fixed. Replaced the capacitors, so now instead of 0V output, 11.5V. Adjustment pot does nothing, so either the pot or resistor network has issues. I suspect the pot... maybe deoxit will do the trick. #hamradio #repair #astron #electronics

"..Starlink-Satelliten.. sie stören auch. So sehr, dass eine Gruppe internationaler Astronomen, darunter Benjamin Winkel vom Max-Planck-Institut für Radioastronomie in Bonn, nun Alarm schlägt. Sie kritisieren, dass die Radiowellen des wachsenden Satellitennetzes den Blick ins Weltall behindern."

Musk's #satellites 'blocking' view of the #universe

by Georgina Rannard
September 18, 2024

"#RadioWaves from #ElonMusk’s growing network of satellites are blocking scientists’ ability to peer into the universe, according to researchers in the Netherlands.

"The new generation of Starlink satellites, which provide fast internet around the world, are interfering more with #RadioTelescopes than earlier versions, they say.

"The thousands of orbiting satellites are 'blinding' radio telescopes and may be hindering astronomical research, according to Netherlands Institute for Radio Astronomy (#ASTRON).

"#SpaceX, which owns Starlink, has not replied to a request from BBC News for comment.

"The satellites provide broadband internet around the world, often to remote places, including challenging environments like Ukraine and Yemen.

"They are also used to connect remote areas of the UK to fast internet. In 2022 tests showed that Starlink could deliver internet speeds four times faster than the average, according to the Department for Digital, Culture, Media and Sport.

"But astronomers say this comes at a cost.

"'Every time more of these are launched with these kinds of emission levels, we see less and less of the sky,' Professor Jessica Dempsey, director of ASTRON, told BBC News."

Their result agrees with other local universe measurements, increasing evidence of the Hubble tension.

Oh, thanks for the reminder to re-watch this video! It's been awhile. Some nice moments with #Credor and #GrandSeiko artisans, and even a stop with the people making the GPS #Astron watches available then!

Coincidentally, I've been wearing a GPS Astron today, but a smaller (and to my eye more tasteful) three-hand model made possible when they introduced the #3X22 movement.

The centre of LOFAR, the largest telescope in the world*, is conveniently situated within cycling distance so a group of us cycled there for the open day last Sunday.

You can read more about LOFAR here:
https://en.wikipedia.org/wiki/Low-Frequency_Array_(LOFAR)

https://www.astron.nl/telescopes/lofar/

* It's described as "the largest radiotelescope in the world which can operate at the lowest frequencies that can be observed from earth" and it's about a thousand km wide, which makes it a nice example of peaceful international scientific cooperation.
