Today my son an I did a thing - we took a video of the @Space_Station with @astro_matthias in it. The video is in visible light, the still in H-alpha.
If you like it, check out the image of
@SeVoSpace!
@HdAstro @Clearskies_SW
The whole thing was quite an adventure

@_GeorgeRudolf @CursedFootprint There has to be a hidden message in there - maybe morse code?

Trotz ☁️☁️ konnte ich gestern mit in der Schule die #Sonnenfinsternis zeigen und sogar ein paar Bilder machen.
War echt toll, könnte man eigentlich jedes Jahr machen 😎
@HdAstro @DLR_next könnt ihr da was machen?

Two Finnish men 'annexed' a Russian diplomat's parking spot in the Finland’s city of Turku, by painting it with the Ukrainian flag.

They called it the result of a "2-man referendum" on "annexing" the spot. The city announced it would not paint over it.

@ClosertoSpace This could be the Buran, that is located in the @museumtechnik in Speyer.

Is there more footage of the Buran actually flying?

[Stefan Hengen @Stefan_OnTheGo]

@Rainmaker1973 Here you can see an animated version by @BenKrasnow:

@Rainmaker1973 Also called the astronauts' astronaut
IIRC that's what @Astro_Mike called him in episode 1 part 2 of @2FunnyAstros

@AndySaunders_1 There is some info about the one in the Technik Museum Speyer @museumtechnik which is well worth a visit:

@AndySaunders_1 That depends how you define fly - in Speyer, Germany is a Buran equipped with engines, which was used for flight experiments.
But that one had not been to space though.

@Rainmaker1973 @colorize_bot
Please colorize it

@GigaBecquerel Nice one - I guestimated the circumference to 2m. This would result in 2500 kg per meter length 😳
(Scrap prices seem to be be 1-3€ per kg)

Jetzt grade gibt es ein Halo über Heidelberg zu sehen!

@astrophysikerin - das müsste ein 22 Grad Ring sein, oder?

[Stefan Hengen @Stefan_OnTheGo]

@sweeper76 Tolles Schaubild - leider gibt es beim Durchmesser auch einen Fehler: 109 Erddurchmesser mussten das sein, nicht Radien.

[Stefan Hengen @Stefan_OnTheGo]

@Plag0n @fermatslibrary If memory serves right, the faked results started before his time there.
There is a whole book about this case: Plastic Fantastic

[Stefan Hengen @Stefan_OnTheGo]

@xkcd I know the feeling - one only wants to mind his one business and take a picture of a celestial body (in my case the sun), and out of the blue a plane appears 🤬

[Stefan Hengen @Stefan_OnTheGo]

@Steinwaelzer Tolles Foto, sehr gelungen! 👍

[Stefan Hengen @Stefan_OnTheGo]

Today I had another attempt at #solarimaging / #sun #Astrophotography - which was suddenly interrupted by @British_Airways BA263.
Somehow I'm not even mad!
Sorry, no other today...
@Clearskies_SW @astrophysikerin

[Stefan Hengen @Stefan_OnTheGo]

@AstroZwerge Falls es dich etwas beruhigt - du bist nicht alleine!

[Stefan Hengen @Stefan_OnTheGo]

Today a brief hole in the clouds appeared and was promptly used for some quick #solarimaging #Astrophotography

@GregDavill Assuming 2/3 the speed of light (which ist reasonable for optical fiber) 800km takes 4ms.
Back and forth are 8ms.
A bit of routing and switching in between there you have it.
18ms are not bad!
