So far, none have looked quite like Earth. If an Earth-like planet was orbiting another star, however, it may look different than our precious pale blue…

    We’ve Underestimated Our Ability to Spot Alien Signals From Exoplanets

    An encouraging new study has found that the interference from exoplanets—planets that orbit stars outside our solar system—has been overestimated in searches for extraterrestrial signals. The results from the study, released last week in The Astronomical Journal, mean that scientists can concentrate on finer frequency shifts, markedly improving the potential effectiveness of campaigns to sniff…
