Cambridge astronomers identify new hycean class of habitable exoplanets, which could accelerate search for life
Signs of life beyond our solar system may be detectable within two to three years, experts have said after rethinking the kinds of planets that may be habitable.
Researchers have mostly looked for planets of a similar size, mass, temperature and atmospheric composition to Earth. But University of Cambridge astronomers believe there may be more promising possibilities after recent work suggested that a “mini-Neptune” more than twice the radius of Earth and more than eight times as massive may also be habitable.
