The slow, invisible leak turning our blue planet red
In short: Earth is losing its atmosphere to the vacuum of space every single minute. Astrophysicist Anjali Tripathi explains the mechanics of atmospheric escape and why our planet could eventually mirror the desolate landscape of Mars.
About 400 pounds of hydrogen plus roughly 7 pounds of helium flee our planet's atmosphere towards deep space each minute. This constant process of atmospheric escape is a fundamental astronomical phenomenon that shapes the evolution of planets over vast timescales.
Tripathi explores how these gradual losses could fundamentally alter Earth's composition. Over a period of a few billion years, this depletion of gases may eventually transform our vibrant blue world into a dry, red environment similar to Mars.
