Verrückter Fakt des Tages: #vfdt
Die Sonne ist hier nicht zu Hause.
Vermutlich ist die Sonne, zusammen mit vielen anderen ähnlichen Sternen deutlich weiter drin im Zentrum der Galaxie entstanden und dann, möglicherweise durch das Einwirken einer anderen Galaxie, nach außen transportiert worden.

That fuzzy patch is thought to be itself a dusty disk that is now forming into moons -- and that has never been seen before.

Yet something is puzzling astronomers — and Betelgeuse's close companion star, recently suggested by observations with our VLT, could be behind it.

That we can see other star systems form blows my mind. This image is a composite of data from JWST, Hubble, and ALMA, and shows a disk called Oph 163131, which is 480 lightyears away.
