Kaya Bulutlarının Olduğu Gezegen: Gün Batmadan Buharlaşıyorlar!

James Webb Uzay Teleskobu (JWST), uzak bir "Sıcak Jüpiter"in atmosferik döngüsünü ortaya çıkararak bilim dünyasını şaşırttı. Microscopium takımyıldızında, Dünya'dan yaklaşık 700 ışık yılı uzaklıkta bulunan WASP-94A b ötegezegeni üzerinde gerçekleşen günlük bulut döngüsü, gökbilimcilerin atmosferik yapısını daha net bir şekilde analiz etmesine olanak tanıdı.

WASP-94A b'de hava durumu tahminleri hızla değişiyor. Kayalık mineralle oluşan bulutlar, gezegenin sabah saatlerinde gökyüzünü kaplarken, atmosferin daha sıcak bölgelere taşınmasıyla akşam saatlerine doğru tamamen yok oluyor. Yıldızına aşırı yakın yörüngede dönen dev bir gaz devi olan bu dünya, konumunun uzaklığı nedeniyle doğrudan görüntülenemese. de JWST'nin yıldız ışığındaki ince değişimleri ölçerek gezegenin atmosferiklelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelelele
