The Real SETI Signal: Not a Message, but a Molecule

Life on Venus? That outrageous-sounding probability understandably made headlines a few weeks in the past. In element, the information grabbed people’s awareness for the reason that Venus seems like these an unlikely place to discover anything alive. The surface area temperature there averages 460 levels C, and the pressure at sea stage is a crushing 93 moments the atmospheric pressure on Earth–except, of course, there is no genuine sea on Venus.

There was another startling element of the life-on-Venus tale, nevertheless: the character of the evidence alone. There are no rovers rolling across Venus. We do not have any samples of Venusian rocks to put less than the microscope. The research for life was conducted from afar making use of radio telescopes, and the hints of life arrived in the type of an really slight radio shadow indicating the presence of an obscure molecule recognised as phosphine.

Jane Greaves, an astronomer at Cardiff University in Wales, and her colleagues utilized the James Clerk Maxwell Telescope in Hawaii and the ALMA radio observatory in Chile to scan for phosphine in Venus’s atmosphere. To their shock and delight, the identified the sign they were being seeking for.

Phosphine on Venus??

What is a biosignal. Challenge of identifying.

Biosignals on Mars? Dunno. Venus, Enceladus, Europa? Genuinely dunno.

What about exoplanets? Could be life in all places.

Will end up with a future entire of odds-makers & no responses.

May well have to settle for the statistics.
