Why can't early black holes not grow by eating dark matter? No radiative pushback, but perhaps too small a cross-section? Would that depend on DM temperature and particle mass, but already excluded by candidate parameters?
I thought I was trained in this #astro business, but... 🤷🏼♂️ #Astrodon
Astrophysikerin Laila Linke berichtet heute im ORF Ö1 Mittagsjournal über die ersten Ergebnisse der Euclid-Weltraummission. Allein im Perseus-Galaxienhaufen hat ein internationales Forschungsteam 600 bisher unbekannte Zwerggalaxien entdeckt. Das neue Teleskop liefert beeindruckende Bilder des bisher unerforschten Universums.
Hey @astro developers 👋 We've got a new Starter template! Try it out if you're looking to build an #Astro site with visual editing for your content team!

Aurora Australis, from Shelly Beach at Port MacDonnell, South Australia. Cheeky five hour drive to catch this and so worth it - absolutely breathtaking to see those beams towering over me. Experience of a lifetime.
Look outside NOW if you’re anywhere close to aurora possible tonight - We are in a light polluted car park in central Newcastle and can SEE MOVING LINES ACROSS THE SKY!! With naked eye!! Visible structure and even a touch of green under streetlights 🤩 Literally never had this before.
Running home to get SLR cameras now. Will be up for a late night! #aurora#KP8#astro
The Elephant's Trunk Nebula IC 1396 was the target of yesterdays clear night and here I would like to share the result:
My first try on a DSO two panel mosaic.
Guiding and banding noise have been quite a problem for this project, well there is always room for improvements...
Disclaimer: This is a "false" color image using a HOO color palette.
Finally got my first proper shot of the Eagle Nebula (M16)!
This target was a real pain to photograph from my location, because I had to get up at 3 AM and M16 still is pretty low in altitude for me... but luckily a gap in the surrounding trees made this 6x600s stack possible.
Obviously Focus and Guiding are not optimal, this is still work in progress to get fixed.
