Our planet’s oceans generate tell-tale light signatures when sunlight reflects off them. Exoplanets with significant ocean coverage may do the same. Can we use the Earth’s reflectance signatures to identify other Earth-like worlds with large oceans? We should be able to, eventually. A new study examined light signatures reflecting off of Earth’s oceans and explored …
