JUST IN: Harvard Scientists Found the First Atmosphere Around an Earth-Like World

Scientists may have just made one of the biggest exoplanet discoveries in history.

For the first time, Harvard astronomers have detected a confirmed atmosphere around a rocky planet in the habitable zone of another star. The planet, LHS 1140 b, located about 48 light-years from Earth, is now considered one of the most promising candidates in the search for another Earth.

In this video, we'll explore how scientists first predicted this discovery using theoretical calculations, why they selected LHS 1140 b from thousands of known exoplanets, how they detected helium in its atmosphere, and why this discovery is such a major milestone in the search for life beyond Earth.

We'll also discuss what makes LHS 1140 b so similar to Earth, whether it could have oceans or a nitrogen-rich atmosphere, why astronomers are so excited about its potential, and whether humanity could ever travel to this fascinating world.

Could this be the closest thing to a second Earth we've ever discovered? Watch till the end to find out!
