Good day all! Upcoming episode of Fireside Fedi!
The #livestream will be on: https://stream.firesidefedi.live
Special Guest: @hfalcke
#Prof. #Astrophysics, columnist D/NL, #bestseller #author 'Lim Dunkeln/Light in the Darkness/Licht in de duisternisi' about the first image of a black hole shadow with the Event Horizon Telescope, that I was deeply involved in. Work at Radboud University, Nijmegen (NL), live near Cologne (D). Am a happy European, Christian, dad, and granddad.
So don't miss it!
It will happen on 10 December 2025 at 14:00 US Eastern Time ( UTC-5 )

Making astronomy accessible for everyone requires developing new and engaging ways to describe astronomical data.
In our latest blog post we talked to sonification experts to learn how astronomical data can be turned into sound, and how this approach can benefit everyone.

“500,000-km Solar Prominence Eruption”
It’s difficult at times to fathom the scale and power of fluid dynamics beyond our day-to-day lives. Here, twists of the Sun‘s magnetic field propel a jet of plasma more than 500,000 kilometers out from its surface in an enormous solar prominence eruption. To give you a sense of scale for this random solar burp, that’s bigger than ten times the distance to satellites in geostationary orbit. (Image credit: P. Chou; via Colossal)

Excited to now share this story; papers have been accepted!
Apep is an awesome system, unlike any other we know about. It is named after the Egyptian God of Chaos - because, well, it is chaos!
Two Wolf-Rayet systems orbited by a third supergiant. As all their winds collide, they form these beautiful structures that have now been observed with #JWST and ESO's VLT.
I had a chat with fellow student from Macquarie Uni. Ryan White who has led one of the two papers that are released about this.
My latest for #SpaceAustralia

[ #Waves and #Plasma] Numerous #moons orbit #Jupiter, including #Io, whose volcanic activity causes the ejection of #matter and the formation of a magnetized #plasma disc—or #magnetodisc—in the equatorial plane of the gas giant.
How does the plasma in this magnetodisk manage to remain in a state of #equilibrium? By emitting waves, according to a new study based on data acquired by the #Juno probe, which has been orbiting #Jupiter since 2016.

A hypnotising view of Paranal in #Chile!
Yet the sky is not revolving around the tip of one of our Auxiliary Telescopes. This illusion is caused by the almost perfect alignment with the southern celestial pole, around which stars seem to trail due to Earth's rotation.
Capturing these circular star trails is no easy task: a slight misalignment can completely ruin the outcome! 😲

For the first time ever, astronomers have unveiled the shape of a star’s explosion at its earliest stage.
The feat was achieved by ESO's Very Large Telescope just a day after the detection of this supernova, as the blast was breaking through the star’s surface.
This brief initial phase wouldn’t have been observable a day later. This will help shed light on how massive stars go supernova.

A dance of two pairs!
While the two Magellanic Clouds shine upon the Atacama Desert in #Chile, two Auxiliary Telescopes of ESO’s Very Large Telescope Interferometer point up to the sky.
Just like our cosmic neighbours move around the Milky Way, the Auxiliary Telescopes can be moved along rails and arranged in different configurations when observing the sky.
