The discovery of a planet in deep space that might support human life has long been a staple of science fiction, but little else.
However, as more and more exoplanets are being found throughout the universe, a large number of new contenders for the ideal Earth 2.0 have emerged.
For instance, Newsweek reported in February 2022 that astronomers had discovered two mini-Neptune exoplanets, which may be evolving into so-called “super-Earths” as they lose their voluminous atmospheres.
However, have any exoplanets been discovered that we could potentially call home? If so, how can we tell from where we are now?
