Is there a higher resolution version of this map available?

Today, that star marked with "Var!" can be imaged with a 6 inch telescope: bsky.app/profile/dobs...
The star that expanded the universe was discovered by Edwin Hubble in 1923 with a 2.5m telescope. The Cepheid star V1 gave first prove that Andromeda is a galaxy outside our milkyway. Today, this #Astrophotography with my little #CelestronOrigin clearly shows this star in the gorgeous spiral of M31.

But the point you are making is interesting, though!

I am sure that you are using the word lie as a rethoric hyperbole here. To me, it's just our eyes (and monitors) that are incapable of displaying and recognizing exponential brightness profiles.

Interesting! The word "kwaksalver" also is equivalent to the old German word for the element mercury, whick is "Quecksilber". So this could be someone who prepares mercury containing ointments which must have been quite common then.

That person in the '70s is exactly me!

Sehr interessante Seite, danke! Vor allem, da ich mich da altersgemäß (und damit vorteilhaft!) einordnen kann.

Das Problem sind ja nicht die 40 Schnitzel, sondern die Aufgabe, deren Energie in, sagen wir, einer Zehntelsekunde umzusetzen. Dann sind wir bei einer momentanen Leistung von 1,5GW!

Toll geschriebener, sehr interessanter und informativer Text!

Möglicherweise nicht mitgerechnet: Posts in den "sozialen" Medien und Chats. Aber wenn man für "Outreach" verantwortlich ist: sind solche Zahlen dann nicht zu erwarten?

Unaere europäischen Hörgewohnheiten machen es leider schwer, die Feinheiten / das Herausragende an so einem Musikstück zu erfassen. Aber es spricht trotzdem etwas an, wenn man sich darauf einlässt.

Taupunkte bis 30°C - um Himmels Willen! 🥵

Den Artikel zur tunebaren Schmalbandfotografie der Sonne fand ich beeindruckend. Die Sonne im Licht einer Helium-Linie - wann hat man so etwas schon mal (von Amateuren) gesehen? Wahnsinn, was manche "Amateure" hinkriegen!
