#astro #question This object was just passing over Brno (21:00-21:03 CET) from NWW to SEE. It started as a small butterfly from light - I thought about some kind of halo around a bright star. But it was moving in satellite speed, and the halo was rotating and growing. Photos are bad because it is from phone.

Black holes suck in everything, including, cats, hypercubes, and Fano planes. I drew and painted this piece with watercolor paint, colored pencil, black ink, and mica watercolor on a 6” square of cotton paper. #doodle #MathArt #geometry #ScienceArt #MastoArt #watercolor #SpaceArt #Astro
