Astrobiology: The Search for Life Beyond Earth | Marta Filipa Cortesão | TEDxUniversityOfPorto

What other environments are there in our solar system and beyond? Could they support life? What would that life look like? In this talk Marta tells us more about the science of Astrobiology and what we can expect in the next space missions to Mars or Jupiter´s moon Europa.
Marta is passionate about Astrobiology and science outreach. Holding a masters degree in Cellular and Molecular Biology from the Faculty of Science of the University of Porto, she did her master thesis at the Centro de Astrobiología (CAB) in Madrid. Currently she is doing a PhD in Space Microbiology at the German Aerospace Center (DLR) in Cologne.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

    Thanks to Marta Cortesão, I am able to find ideas for my research to seek Life outside Solar System. A simple talk, that drives me to understand a little more about how Life emerged in the beginning. 😇

    Some astrobiologists think that we might not recognize alien life if we found it. If that is true, could things on earth be alive that most people think just undergo chemical reactions like crystals?

      It is not unthinkable, as there are many different definitions of what life is exactly. A virus for example, it can not replicate without a host cell and does'nt really have metabolic processes, therefore under one defitition it would not be considered alive. If you take the ability of growth and replication as a defining factor of life. A Virus very well might be considered as beeing alive, because oncce it has taken over a cell it can replicate its own DNA. So because of the lack of a clear definition, there could be a lot of things we have not found yet on our planet. I am no expert however, so please take my word with a grain of salt ;)

      Honestly you'd know if that was your path....right? Like only a soccer player knows how to become a pro soccer player or someone who wants to be a firefighter knows to volunteer and take school on it. Id say naturally you'd do that research wouldn't you?

    Very interesting discussion. I am always open to comment on my GRgone channel regarding microbes in low/zero gravity. Thx. Also, Space Medicine and Biology Visionaries on Facebook.

      Library of Oral Health in Microgravity Space medicine? As in finding vaccines or cures for potentially harmful microbes in space? I've always wanted to be a medical scientist and astrobiology has always been a passion of mine. Is there a career choice that includes both of those?

    Unless God intended for there to be life on other planets, then Earth is the only life containing planet in our universe. ISAIAH 45 verse 18.

      michael cintron I feel kinda bad tbh. Can you imagine having such a limited worldview that you can't and don't want to even imagine life existing elsewhere in the universe and ignoring blatant evidence? With how massive the known universe is, how can anyone even think to believe that we're alone? My future profession literally depends on aliens existing lmao.
