What is the longest river in Antarctica?

The Onyx

The Onyx, defying the extremes, flows in one of the most inhospitable environments on Earth: Antarctica. Unique for its seasonal flow reversal, it reflects the paradoxes of a frozen continent harboring resilient life. Its existence underscores the importance of research on life adaptations in extreme conditions and the impacts of climate change in vulnerable regions. The Onyx reminds us of the austere beauty of our planet and the importance of preserving ecosystems as fragile as they are exceptional.
