Sometimes You Just Can't Put a Ring on It: Setting Constraints on Rings around Moons from Magnetic Fields https://ui.adsabs.harvard.edu/abs/2026arXiv260322722E/abstract #nbody #astrodon
Centaurus A
A relatively nearby galaxy, which is visible as a smudge in binoculars if you know where to look.
In radio light, it is the brightest thing in the sky, screaming static at us. The accretion disk around its central black hole is shooting out jets of super hot gas, which are radio-loud. I don’t have enough data in this set of images to make those jets visible. That’s on the todo list :-)
This is three hours of data during a new Moon, when the sky was nice and dark.

Una resonancia orbital es cuando los cuerpos ejercen una influencia gravitacional periódica y regular entre sí.
Por ejemplo, dos planetas que orbitan una estrella estarían en una resonancia 2:1 cuando uno de ellos tarda el doble que el otro en orbitar la estrella.

In the future, we might see one million more satellites in Earth's orbit. The consequences to astronomy would be devastating.
Fighting for a fair and sustainable usage of space, for astronomy and humanity — that's Betty Kioko's job as ESO’s Institutional Affairs Officer.
