You'll likely catch this image a million times in your various feeds: Earth as seen by Reid Wiseman from Artemis II en-route to the Moon.

My first thought? That's *really* noisy 🧐

But then I realised – it's the *nightside* of Earth, illuminated by the almost full Moon, not the Sun 🌕

The bright limb at lower-right is where the dayside starts, & the fact that you can see aurorae, airglow, & cities in Europe, Africa, & S & N America also gives the game away.

Cool.

Coming up soon: the 40th anniversary of the ESA Giotto probe’s flyby of Comet 1P/Halley, with closest approach at 00:03:02 UTC on 14 March 1986.

Giotto flew within 596 km of the comet at a relative velocity of ~250,000 km/h, so it was all over quickly, but remarkable views of the 14.5 km long dark icy monster were had.

Albeit not this composite made later by Nick Thomas on the Giotto team.

What happened as images streamed back to live TV is another story 😬✌️

Who remembers that night?

#Münster beweist: Mit Engagement und strategischer Planung kann eine Stadt zu einer echten Fahrradstadt werden.

Im Vergleich zu allen Großstädten Deutschlands hat Münster den höchsten Radverkehrsanteil. Rund 47% aller Wege werden dort mit dem Fahrrad zurückgelegt. 🤩

Nicht umsonst ist die Stadt mit 320.000 Einwohner:innen auf dem ersten Platz in ihrer Ortsgrößenklasse im ADFC-Fahrradklima-Test 2024.

Protip:

When designing a user interface, imagine some old woman using it, say Margaret Hamilton, and she's clicking your app's buttons and saying to you, as old people do,

"Young whippersnapper, when I was your age, I sent 24 people to the ACTUAL MOON with my software in 4K of RAM and here I am clicking your button and it takes ten seconds to load a 50 megabyte video ad and then it crashes

I'm not even ANGRY with you, I'm just disappointed."

Twitter-Alternative: Mozilla will frei zugängliche Mastodon-Instanz einrichten

Ab Anfang 2023 will Mozilla an einer "gesunden Social-Media-Alternative" mitarbeiten und eine Instanz im Fediverse einrichten. Mastodon sei dafür ideal.
