The Leo Triplet - three spiral galaxies 35 million light-years away in Leo.
NGC 3628 appears perfectly edge-on, its dust lane and warped disk shaped by billions of years of tidal interaction. M65 and M66 complete the trio with asymmetric arms and disrupted structure.

Ihr mach das alles zu kompliziert. Niemand muss auf die Veröffentlichung der Epstein-Akten warten.
Es gibt Tausende Opfer. Glaubt Ihnen.
Was das Schauspieler-Arschloch angeht: Ächtet jeden, der ihm beispringt.
Und bei der nächsten anzüglichen Bemerkung lacht Ihr nicht. Ihr fragt nach: "Wie meinst du das?" Nicht locker lassen. Ihr werdet sehen, was das für mickrige Typen sind. Frauen brauchen unseren Beistand, schon im Kleinen.
The planetarium at Albert-Schweitzer-Oberschule Chemnitz is coming back to life. We're kicking things off with the Tag der Astronomie on 28 March – free planetarium shows, telescopes in the courtyard, and live views through the observatory. No tickets, no registration.

New Skywarden update v0.24 🎉
No more duplicates - objects now only appear once in the list but show all catalogue IDs.
Proper previews - finally, every object shows a nice preview image, thanks to CDS hips2fits and DSS2 survey.
Check it out at https://skywarden.app

M106 is one of those objects that rewards a closer look. What appears to be extra spiral arms is actually shock-heated gas pushed out of the galactic plane by jets from an active nucleus. This field also captures NGC 4217 edge-on, the interacting pair NGC 4231/4232, and several fainter neighbors.

Und Lilly Schöder von der taz fällt in ihrem Kommentar nichts besseres ein, als dass Banksy gut beraten wäre, seine Arbeit (aus Protest gegen die Offenlegung) einzustellen:
"Mission erfüllt ☠️" nennt sich solch ein Angriff des rechten Backslashs.

Skywarden and Theo are free and will stay that way.
I've been thinking about how to keep them sustainable - and ruled out ads, paywalls, and subscription models one by one. Instead, both apps will show a small, dismissible message asking for support. No restrictions, no difference between users.
The full reasoning: https://adfr.io/thoughts/20260316_no_ads_no_paywall_just_a_request

Sh2-171 – The Question Mark Nebula in Cepheus. A two-panel mosaic covering over 100 light-years of active star formation, powered by Berkeley 59 — a cluster just 2 million years old. Its O5V star BD+66 1673 burns at 45,000 Kelvin, sculpting the dark pillars visible throughout the frame. Processed in Hubble Palette (HSO).

Skywarden now supports full horizon profiles — but getting one required either a €20 app or actual surveying hardware.
So I built Theo: a free PWA that uses your phone's sensors and camera to capture azimuth/altitude pairs and export a .hrz file compatible with Stellarium, SkySafari, and Skywarden.

Skywarden gained support for detailed horizon profiles - but creating one required either expensive surveying hardware or apps that cost €20–30 for a task most astrophotographers do once or twice. So I built Theo: a free PWA that uses your phone's sensors and camera to capture azimuth/altitude pairs around the full 360° and export them as a .hrz file. This is the story of why it exists, how the sensor math works, and where it fits into the Skywarden workflow.
AI-Assisted Development: One month into Claude Code, reviewing AI code and shipping apps fast. This is my experience so far.
