In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar. Hosted on Acast. See acast.com/privacy for more information.
On October 19th of 2017, an interstellar object was observed in our solar system for the very first time. Observed through Hawaiian telescopes, scientists named it Oumuamua. What has followed, is a curious exploration into what, in fact, this interstellar visitor actually is. The topic of of borderline scientific brawls, new Harvard papers this week suggest the possibility that Oumuamua is in fact a solar sail, hull, or ship-based alien probe. This week, on The What If? Podcast, we dive into what makes this object so different from the comets and asteroids we're familiar with, and why the hypothesis of some very smart people lead us down a line of questioning, that entertains the possibility of alien life.

En octobre 2017, l'astrobiologiste Karen J. Meech a reçu le genre d'appel attendu par tout astronome : la NASA avait aperçu le tout premier visiteur venu d'un autre système stellaire. La comète interstellaire — un objet de 400 mètres de long qui a été baptisé ‘Ouamuamua, « éclaireur » ou « messager » en hawaïen — a soulevé des questions étonnantes : serait-ce un morceau de roche d'un nouveau système stellaire, un reste broyé provenant de l'explosion d'une supernova, la preuve d'une technologie extraterrestre ou quelque chose de complètement différent ? Dans cette conférence captivante, Meech raconte comment son équipe a couru contre la montre afin de trouver des réponses à ce cadeau surprise venu de loin.

2017년 10월, 천체생물학자인 캐런 미치는 천문학자라면 누구나 기다렸을 전화 한 통을 받았습니다. NASA가 다른 항성계로부터 온 최초의 방문객을 목격했다는 전화였죠. 약 800 m 길이의 물체인 이 성간 혜성은 하와이 말로 '정찰병' 혹은 '전령'이라는 뜻의 '오우무아무아(Oumuamua)'라고 이름 붙여졌으며, 여러가지 흥미로운 의문들을 낳았습니다. 이것은 새로운 항성계에서 온 바위 잔해일까요? 아니면 외계인의 기술일까요? 어쩌면 양쪽 모두 일까요? 이 흥미로운 강연에서 미치 박사는 멀리서 온 이 뜻밖의 선물에 대한 답을 찾기 위해 자신의 연구진이 어떻게 시간과 싸웠는지 이야기합니다.
Im Oktober 2017 erhielt die Astrobiologin Karen J. Meech den Anruf, von dem jeder Astronom träumt: die NASA hatte den allerersten Besucher aus einem anderen Sternensystem entdeckt. Der interstellare Komet von 0,8 km Länge wurde nach dem Hawaiianischen Wort für Kundschafter oder Bote „’Oumuamua“ genannt und hat faszinierende Fragen ausgelöst: War er ein Gesteinsbrocken aus einem neuen Sternensystem, zerkleinertes Material einer explodierten Supernova, der Beweis für außerirdische Technologie oder doch etwas ganz anderes? In diesem fesselnden Vortrag erzählt Meech die Geschichte, wie sie mit ihrem Team gegen die Zeit arbeitete, um Antworten zu diesem unerwarteten Geschenk aus der Ferne zu gewinnen.
Em outubro de 2017, a astrobióloga Karen J. Meech recebeu a ligação que todo astrônomo espera receber um dia: a NASA tinha detectado o primeiro visitante de outro sistema solar. O cometa interestelar, que tinha quase um quilômetro de comprimento e foi chamado 'Oumuamua, palavra havaiana que significa "escoteiro" ou "mensageiro", levantou questões intrigantes: seria um destroço de um novo sistema estelar, um fragmento da explosão de uma supernova, evidência de tecnologia alienígena ou nada disso? Nesta palestra fascinante, Meech conta a história de como a equipe dela correu contra o tempo para buscar respostas sobre o presente inesperado de algum lugar distante.

El cometa interestelar, un objeto de casi 800 m de longitud que luego bautizarían como 'Oumuamua, "explorador" o "mensajero" en hawaiano, generó preguntas intrigantes: ¿era acaso el resto rocoso de un nuevo sistema estelar, material que se desprendió con la explosión de una supernova, tecnología extraterrestre, o algo totalmente distinto? En esta fascinante charla, Meech nos cuenta la historia de cómo su equipo trabajó día y noche para encontrarle respuesta a este inesperado regalo proveniente de sitios remotos.
