@astro_jcm@mastodon.online In this particular case, how do you know what the opening angle of the cave holes is?

@bluejay@ohai.social @vicgrinberg@mastodon.social I think it has more to do with how bright stars in front of dark clouds of the Milky Way stand out at a dark observing site. I've heard from a number of people who had that impression after observing from observatories on the Atacama desert and I have it there as well. Was it really that dark in the Artemis capsule, though?

@sundogplanets Just curious: What does "star-subtracted" mean here?🤔 (I still see a large number of pretty compact objects.)

@skyglowberlin @GalacticRAVE I cropped both images to the region around what I believe to be the SN and put them side by side. Do you now see it?

@kuketzblog@social.tchncs.de Danke für den Hinweis. Solche Vorwürfe ohne Konkretes und dann noch für eine andere Plattform machen mich ja immer neugierig... Allerdings habe ich da jetzt nicht sooo viele Posts gefunden, dass mir einleuchtet, warum man tatsächlich davor warnen müsste?! Sollte man dann nicht auch bei SPON aufpassen? 🤔

@pikarl @ThomasKrumenacker @riffreporter Verstehe ich nicht. Warum soll die Waldbedeckung vor Millionen von Jahren heute relevanter sein als die (wohl sehr viel dichtere) vor z.B. 5000 Jahren? (Finde das Interview übrigens furchtbar, die Methoden seiner Erkenntnisse werden eigentlich nicht diskutiert.)

@astro_jcm When configured nicely a modern Alpine is still way faster to react and use than e.g. Thunderbird. There are very few mails with very complex HTML content that it does not handle well.
