“We give off waste heat (from industry and homes and so on) and artificial light at night, but perhaps most significantly, we produce chemicals that fill our atmosphere with compounds that wouldn’t otherwise be present. These artificial atmospheric constituents just might be the thing that gives us away to a distant alien species scanning the galaxy with their own powerful telescope.”https://phys.org/news/2022-02-webb-telescope-civilizations-air-pollution.html
Or, as Futurism puts it: “SCIENTISTS ALREADY PLOTTING HOW James Webb COULD DETECT ALIEN CIVILIZATIONS WHOA.”

Scientists have proposed aiming the James Webb space telescope the Trappist system, specifically Trappist-1e.
Really hope this isn’t what they find…
