Thanks to a new remote sensing technique, astronomers may soon be able to detect the presence of multicellular life (like trees) on planets outside of the Solar System.Excitingly, we’ve been able to detect the composition of atmospheres on a handful of planets orbiting other stars. But if next-generation space observatories go online within the next couple of decades, some scientists propose using a new technique to determine details such as tree-like multicellular life on extrasolar planets.
