météorites : pourquoi la pluie d’étoiles filantes attendue cette nuit pourrait être exceptionnelle

étoiles filantes

Les Êta Aquarides sont une pluie de météores très active qui produit jusqu’à 50 météores par heure. Déjà présentes dans le ciel en mai 2023, elles sont de nouveau observables ces jours-ci, rapporte La Voix du Nord.

Quand le phénomène est-il observable à son maximum ?

Le phénomène a commencé le 19 avril et doit se poursuivre jusqu’au 28 mai. En raison de la nouvelle lune prévue pour le 8 mai, les conditions de lumière sont particulièrement adaptées ces 5 et 6 mai où le ciel est particulièrement sombre et donc idéal pour l’observation d’étoiles filantes. L’heure idéale pour les observer se situe entre minuit et trois heures du matin.

Comment les observer ?

Pas besoin de jumelles ou d’autres appareils, mais il est conseillé de s’éloigner de la pollution lumineuse et donc des villes pour les apercevoir. Et elles devraient être particulièrement présentes en regardant l’horizon vers le sud-est et particulièrement vers la constellation du Verseau.

Pourquoi cette année pourrait être exceptionnelle pour l’observation d’étoiles filantes ?

Les scientifiques prédisent que cette année pourrait être exceptionnelle. Une étude publiée dans Astronomy & Astrophysics suggère ainsi que la pluie de météores des Êta Aquarides de 2024 pourrait être l’une des plus puissantes du siècle, selon une étude américaine, relayée par Science et Vie.
