SpaceX Starlink satellites photobombed my Northern Lights photos!
We've known for awhile that increasing numbers of satellites are a problem for astronomy and astrophotography. I had my own issues with SpaceX's Starlink sat...YouTube
Happy Halloween 🎃
Here are the pumpkins I carved this year: An active red dwarf star and its gas giant planet. I call it an exo-pumpkin.

This plot shows the time it takes to integrate the Solar System for 5 billion years. In 1950 it would have taken over a million years. Today it takes 1 day. The bottom right point is for our WHFast512 integrator which uses #AVX512 instructions: https://astro.theoj.org/article/84547-whfast512-a-symplectic-n-body-integrator-for-planetary-systems-optimized-with-avx512-instructions

🚨BIG SCIENCE NEWS 🚨
And our results (along with our international colleagues) have dropped!
Our team (and others) have started to see the strongest evidence as yet of the stochastic gravitational wave background - ripples in space-time cause by ALL the supermassive black holes in the history of the Universe colliding!
We use pulsars to study these riplles and we needed almost 20 years of data to even get the first hints! It's the long game!
I'm a co-author on the Aussie papers (as part of my work) but I also wrote about it here in my latest feature article on #SpaceAustralia
This is why I have been going on about pulsars for a few weeks now - this was coming!

Where is NGC 6355?
Using the "Our Galaxy" app, we show where the globular cluster NGC 6355 is located in our galaxy. The cluster is deeply embedded in the galactic bulge and i...YouTube
In my previous life I used to study how galaxies form and evolve. I also helped my peers get their data as a support astronomer at ESO's Paranal Observatory in Chile. I now work full time as Media Officer at ESO's HQ in Germany.
I'm also an avid astrophotographer! Below is a pic of my previous "office" in Chile. 🤩
