ESOcast 87: Planet found around closest Star

This is the ESOcast that no viewer will want to miss. We discuss the result of the quest to find a planet around the closest star to the Solar System.

The Pale Red Dot campaign aimed to find a planet orbiting our nearest stellar neighbour, Proxima Centauri. Incredibly, the quest succeeded and the team did indeed find a planet. Even more excitingly, the planet, Proxima b,  falls within the habitable zone of its host star. The newly discovered Proxima b is by far the closest potential abode for alien life.

In this ESOcast, the results of this groundbreaking research are explained in detail, providing insights into the following points:

* The extensive verification process the team went through to ensure this result was accurate.
* The factors for and against the possibility of life on Proxima b.
* The nature of a “habitable zone” around a star.

The discovery of Proxima b is a major science result, making this ESOcast a must for those of you curious about one of the most intriguing questions in astronomy — “are we alone?”

  1. humans just arn't innovative enough this is one of the greatest discoveries in the history of mankind and if a video of Kim Kardashian twerking was uploaded it would have millions more views and be much more talked about and noticed its sad really we are going to get no where like this.

  2. I wish Yank women would cop a clue from how this woman talks. She does not block her nose and sound like a nasal drip. She uses her mouth AND her nose to speak, and she sounds wonderful. Note also the complete absence of vocal fry, also beloved of Yank women. Yuk!!! Enough with those whiney, croaking Yank women.

  3. Too much radiation. 400 times more than on the Earth. It's much worse than one giant Pripyat Stalker zone there, it's not habitable. And practically useless for humanity. So relax your butts fellas.

  4. It blows my mind that this type of discovery isnt going viral. THIS IS HUGE!!! im so excited to be living in this time period despite all the bs politics and govt.

  5. Estaremos sós neste vasto universo?? Uma pergunta que ainda não obteve resposta!!! Somos os únicos seres inteligentes? Acreditar ou não eis a questão?? Existir ou não existir?? No entanto há certos retratos extra que intrigam …como pinturas rupestres…rudimentares mas muito perceptíveis…como na idade média quadros pintados …O foco é Graal das pesquisas que nunca mais se detenha a continuidade de conhecimento e de desistir de encontros com outras vidas!! Que nos trará esta busca??

  6. It's probably tidally locked, so there'd be a habitable band around the terminator. Winds would be high from temperature differentials between perpetual noon and perpetual midnight. Life is still feasible, though.

  7. I personally do not believe a planet like Earth will exist so close to us.
    People also believed Venus would be Earth-like, they were wrong, very, very, wrong….

    and if you take the distance Venus is from Earth, and also take into account the technological progression from that time(which was not linear, more exponential-based)….It makes me feel it will be another Venus-scenario, that place will not be Earth-like….

    OR at its best:

    I'm thinking it will be like Mars.
    Waiting for 26/30 years for a maybe is pretty sh*t, its better if you take into account that in space there are so few maybes to begin with (its a pretty empty void type place where pretty much everything is not like Earth), I hope humanity is not pooling too much resources in this "maybe"……..
    It feels like everyone is over-excited, and getting themselves ready for heart-breaking disappointment (here's a tip: stop being excited about anything, that way your heart beats slower and you live longer)….

  8. Since life begins human intrested exploring planet. We come to proxima b. From a different planet where life started. And thay had some space ship to fly to proxima b.then to planet Mars to the planet of earth.🔭🙂
