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.
We had a super fun (surprisingly tiring) afternoon watching the #eclipse. The big zoom lens, telescope, and solar filters worked great. Neighbors came out and we watched the sun spots get covered up. The telescope had enough detail to see the craggily edges of the moon. Milli enjoyed the sun and observed some diffraction from inside. One neighbor said “you have the coolest gizmos on the block!” All things considered, it was a lovely experience, no regrets. #Astronomy#Astro#Eclipse2024
