NASA выясняла, какой может быть атмосфера на планете Proxima b

Исследователи подсчитали уровень атмосферной потери кислорода с учетом информации о возрасте Proxima b.

Экзопланета Proxima b, которая также известна, как Вторая Земля, скорее всего, лишена воды и кислорода.

Таким образом, по мнению специалистов NASA, эта планета непригодна для жизни, сообщает издание Gizmodo. 

Команда ученых разработала модель, чтобы показать, как высокоэнергетические рентгеновские лучи и ультрафиолетовое излучение от красных карликов влияют на утечку кислорода из атмосферы планеты в открытый космос.

«Чем сильнее там может быть рентгеновское и ультрафиолетовое излучение, тем больше электронов генерируется и тем сильнее становится эффект выброса ионов», — объясняет Алекс Глосер, астрофизик NASA.

Исследователи подсчитали уровень атмосферной потери кислорода с учетом информации о возрасте красного карлика и Proxima b. Ученые вычислили, что планета очень часто подвергается солнечным штормам, атакующим ее атмосферу примерно каждые 2 часа. Вероятно, запас ее кислорода полностью закончится примерно через 10 миллионов лет.

 

Напомним, что ранее специалисты NASA назвали 2016 год самым жарким в истории за все время наблюдений, начиная с 1880 года.
