#astronomie la #comete #C2026A1 #MAPS approche du soleil et va frôler sa surface tout début avril 2026. Si elle survit à ce raze-mote de la mort (quelques millions de km seulement) nous aurons verrons une comète très spectaculaire au coucher du soleil, mais elle peut aussi très bien se disloquer comme la comète ISON en 2013. La commission des comètes à mis en ligne le webinaire de ce week-end sur le sujet :

This thing is about (in a few weeks) to fly within spitting distance of the Sun. If it survives that (not likely) it should be spectacularly bright!
Where are we now?
