Astronomers spot what might be Earth’s chilly twin just 146 light-years away: Earth-sized, orbiting a dim Sun-like star, probably locked in a perpetual deep freeze at -90°F or worse. Sure, it could theoretically have a super greenhouse atmosphere to thaw things out and host liquid water (51% optimistic odds!), but right now it’s giving “frozen Mars but with worse lighting” vibes. Pack your parka and CO? tanks if you’re booking a ticket—confirmation pending, but this “habitable” candidate is basically the universe’s idea of a cold shoulder.
