The Seven Wonders of Exoplanets Ep7 How far is the closest exoplanet to us 25.12.2023

Il più vicino è un esopianeta che orbita intorno alla stella Proxima Centauri. La luce, che è la cosa più veloce nell’universo, impiega 4 anni ad arrivare a Proxima Centari. I nostri razzi viaggiano molto più lentamente della luce e quindi, con la tecnologia di oggi, impiegheremmo 135,000 ad arrivare a Proxima Centauri. Abbiamo bisogno di razzi più veloci! The closest is an exoplanet orbiting the...

The Seven Wonders Patrick Ep7 Planetary Defense Research 25.12.2023

Le risque d’impact d’astéroïde est en fait un sujet fascinant. Pas tellement angoissant, puisque pour l’instant nous n’avons aucune menace, mais fascinant, parce qu’il porte sur des objets qui sont absolument excitants pour les scientifiques : ils évoluent dans un environnement qui est très différent de celui de la Terre et qui défie encore notre intuition. On l’a vu avec les missions récentes, la...

The Seven Wonders Patrick Ep6 Planetary Defense Communication 25.12.2023

Comme tous les sujets qui portent sur une menace, la communication est extrêmement importante. On peut dire très vite n’importe quoi et il faut faire attention à ce que le public comprenne ce que l’on dit et puisse comprendre si la menace est réelle ou pas. Tout ça n’est pas facile, donc nous nous entrainons à communiquer avec le public cette notion de risque d’impact d’astéroïde et à être transpa...

The Seven Wonders Patrick Ep5 Planetary Defense Coordinated International Response 25.12.2023

Le risque d’impact d’astéroïde est un problème qui concerne le monde entier. Pour l’aborder, il faut avoir une réponse internationale coordonnée à ce problème. C’est pour cela que l’on a mis en place, sous l’égide de l’ONU, des groupes de travail qui s’intéressent à définir une réponse coordonnée. Si un objet nous arrive dessus, qui va monter la mission ? Qui va sauver le monde ? Tout ça doit se d...

The Seven Wonders Patrick Ep4 Planetary Defense Avoidance 25.12.2023

Se protéger de l’impact d’un astéroïde nécessite que l’on puisse faire en sorte que si un objet nous arrive dessus il évite la Terre. Pour ça, il faut définir des techniques qui permettent de dévier la trajectoire d’un astéroïde qui nous arrive dessus. Il y a plusieurs méthodes qui marchent sur le papier, certaines sont d’ailleurs très élégantes, mais très complexes à mettre en œuvre. En gros, il...

The Seven Wonders Patrick Ep3 Planetary Defense Protection 25.12.2023

Pour se proteger du risque d’impact, comme on dit il vaut « mieux connaitre son ennemi ». Meme si les asteroides sont plutot nos amis, mais comme ici ils nous menacent on va les considerer comme un ennemi. Pour le connaitre il faut le caracteriser, c’est-a-dire comprendre quelles sont les proprietes physiques qui constituent ces objets. Est-ce que ce sont des roches monolithiques, des agregats, de...

The Seven Wonders Patrick Ep2 Planetary Defense Observation 25.12.2023

Pour pouvoir se proteger du risque d’impact, il y a d’abord une chose a faire, c’est de decouvrir ces objets et de predire leur arrivee sur Terre. Cela n’est pas simple car ce sont de tous petits objets qui emettent une tres faible luminosite, donc cela necessite une tres grande couverture du ciel. On le fait depuis la Terre avec telescopes, et on a rescense la plupart des corps de plus d’un kilom...

The Seven Wonders Patrick Ep1 Planetary Defense Risk of impact 25.12.2023

Je suis Patrick Michel, astrophysicien, directeur de recherche CNRS à l’Observatoire de la Côte d’Azur en France. Voici les sept merveilles de la défense planétaire. Le risque d’impact d’asteroide est l’un des moins probables mais il a de hautes consequences. Il a un avantage : c’est le seul que l’on peut predire et eviter avec des moyens raisonnabes et realisables que l’on est en train de mettre...

The Seven Wonders of Exoplanets Ep6 How we discover exoplanets 25.12.2023

Il più vicino è un esopianeta che orbita intorno alla stella Proxima Centauri. La luce, che è la cosa più veloce nell’universo, impiega 4 anni ad arrivare a Proxima Centari. I nostri razzi viaggiano molto più lentamente della luce e quindi, con la tecnologia di oggi, impiegheremmo 135,000 ad arrivare a Proxima Centauri. Abbiamo bisogno di razzi più veloci! The closest is an exoplanet orbiting the...

The Seven Wonders of Exoplanets Ep5 What are super Earths 25.12.2023

Non esistono super-Terre intorno al sole, ma sono tra gli esopianeti più comuni. Ci sono molti tipi di super-terre, tra cui “grosse” Terre, o “grosse” Veneri o piccoli Nettuni, ma anche pianeti più esotici come “i pianeti oceano”, interamente coperti da oceani in superficie, con molta più acqua di quanta abbiamo sulla Terra. There are no super-Earths around the sun, but they are among the most com...

The Seven Wonders of Exoplanets Ep4 Why are exoplanets so diverse 25.12.2023

Non lo sappiamo con certezza, e vogliamo scoprirlo nei prossimi anni. Pensiamo sia dovuto a come si formano e alla loro storia. Per esempio, abbiamo scoperto molti “Giovi caldi” che orbitano molto vicino alla loro stella, ma si sono formati lontano e poi sono migrati successivamente. We don't know for sure, and we want to find out in the coming years. We think it's due to how they form and...

The Seven Wonders of Exoplanets Ep3 How long does it take for a planet to complete an orbit aroud 25.12.2023

Dipende da quanto è distante il pianeta dalla stella. Per esempio la terra ci mette circa 365 giorni. Altri pianeti nel sistema solare ci mettono molti anni perché più distanti dal sole. Alcuni esopianeti, mettono meno di un giorno per completare un’orbita intorno alla propria stella, e sono così caldi che le rocce in superficie sono fuse. It depends on how far the planet is from the star. For exa...

The Seven Wonders of Exoplanets Ep2 How do we discover exoplanets 25.12.2023

Circa 5000, ma il numero di pianeti conosciuti cresce ogni giorno. I primi esopianeti furono scoperti nel 1992 intorno ad una stella “morta”, da uno scienziato polacco e uno canadese (Wolszczan e Frail). Nel 1995 fu scoperto il primo esopianeta intorno ad una stella simile al nostro sole da due scienziati svizzeri (Mayor e Queloz), che hanno recentemente ricevuto il premio Nobel per questa scopert...

The Seven Wonders of Exoplanets Ep1 What is the sun 25.12.2023

Il sole è una stella, come quelle che brillano in cielo la notte. Le stelle sono fatte di idrogeno, l’elemento più comune nell’universo e sono caldissime, perché al loro interno l’idrogeno viene bruciato. Negli ultimi vent’anni abbiamo scoperto che quasi tutte le stelle hanno pianeti che orbitano intorno, come fa la Terra col il nostro sole. Li chiamiamo esopianeti. The sun is a star, like those t...
