Die Expert:innen werden nicht müde zu betonen, dass der Asteroid 2024 YR4 keine ernsthafte Gefahr für uns darstellt. Tatsächlich nimmt ja die Wahrscheinlichkeit auch ab.
Dennoch hat mich interessiert, was denn getan werden kann, um Asteroiden abzulenken, die auf die Erde zusteuern. Richard Moissl von der @esa hat meine Fragen beantwortet.
The journey of #Gaia from @esa has not only changed our understanding of the Milky Way, but also transformed those of us who worked on this extraordinary mission. It’s been an adventure that made us question who we are and what we can achieve together. 🌌✨ #GaiaMission#SpaceExploration @esascience
"However, sky watching veteran and reentry tracker, Jonathan McDowell who works at the Harvard–Smithsonian Center for Astrophysics, told Inside Outer Space that there is "no obvious space candidate. I am not convinced it's not from an airplane. Don’t see obvious evidence of reentry heating.""
Well, my skepticism about the Kenya space debris may have been wrong. I reviewed the data again, concluding that Space Force estimates of the Ariane V184 upper stage reentry are unreliable; an assocation with this object can’t be ruled out.
[Pour le plaisir des yeux ... 🤩 ] Avez-vous vu ces images de la surface visible du #Soleil - la #photosphère - récemment acquises par les instruments embarqués à bord de la sonde #SolarOrbiter de l' @esa ?
Ces trois images témoignent de la #dynamique de notre Soleil - notamment, des mouvements de #plasma à sa surface, de l'#éjection de matière depuis les #tâches sombres le long des lignes de champ #magnétique.
